After “recovering” from Covid-19, many people have suffered lingering malaise: labored breathing, foggy thoughts, chronic fatigue.
It’s awful, and it’s ill-understood. Trials are ongoing to try to help people, but, honestly, medical doctors don’t know what to do. Akiko Iwasaki, an immunologist at Yale, has been investigating Long Covid since late 2020 and has a long list of experimental therapies that her team would like to test.
In an interview with Jennifer Couzin-Frankel for Science magazine, Iwasaki said “As a basic scientist, of course I’d like to have all the pieces of the puzzle” before giving people untested therapies, “but the patients, they cannot wait.”
Unfortunately, longstanding prejudice in the medical community about what counts as a “real” disease has meant that a promising medication, Prazosin, apparently isn’t even on the list of therapies to try.
Full recovery from an upper respiratory infection like influenza or Covid-19 often takes months. This timeline is very noticeable among athletes, whose performance is exquisitely sensitive to any disturbances in breathing. Even though young people recover from many illnesses much more quickly than others, an elite high school athlete who catches a bad respiratory infection will often suffer for an entire sports season.
This is after the acute phase of coughing and viral production has passed: bodies can take a long time to heal.
Diabetes, heart damage, and a wide range of autoimmune conditions can also be triggered by viral infections (or, often, a body’s immune response to viral infection). Even after a virus has been cleared from a person’s body, the collateral damage caused by the infection or the person’s immune response can result in lingering maladies.
We shouldn’t be surprised that a wide range of persistent problems would appear after the vast majority of the world’s population just had their first encounter (and second, and third …) with a novel coronavirus.
Also, common symptoms of Long Covid – sleep disturbances, muddled thoughts, chronic fatigue, unexpectedly low cortisol, “odd” immune responses, gastrointestinal distress – match common symptoms of PTSD. For many people, Long Covid probably is PTSD.
Please note that I’m not saying that Long Covid isn’t real!
PTSD is real. PTSD causes real physical effects. But for some reason – perhaps because PTSD has a partly psychological origin – PTSD is often considered a less meaningful condition by both the professional medical community and our society at large.
In an opinion essay for the New York Times – “If You’re Suffering After Being Sick with Covid, It’s Not Just in Your Head” – sociologist Zeynep Tufekci inadvertently perpetuates this prejudice, the idea that conditions that have mental causes aren’t as important. I don’t believe that this was Tufekci’s intent – after all, she does an excellent job listing many conditions that the medical community incorrectly discounted in the past.
But conditions that target the brain matter, too! Honestly, it shouldn’t be a hard sell to convince people that brains are at least as important to the human experience as kidneys, lungs, livers, or arteries.
And yet, here we are, living in a world where migraines, depression, or PTSD are considered less “real” than other conditions.
Most likely, what we’ve been calling Long Covid will turn out to be a variety of different conditions. Some people have suffered inflammation or damage to their hearts or lungs that will last a long while after viral clearance. Some people are experiencing the opportunistic reactivation of other latent viruses.
But many cases of Long Covid are probably PTSD. Which is a real condition, with real physiological effects, and there are real medications – like the blood pressure medication Prazosin – that can help in recovery.
We shouldn’t let prejudice about which conditions count keep people from the treatments they need.
During the first year and a half of the Covid-19 pandemic, the local county jail wouldn’t admit volunteers. Incarceration in the United States sounds crummy most of the time, but most of the people I’ve communicated with have said that things were even worse during the pandemic: more fear, more tension, fewer opportunities to do much of anything either than sit & worry.
Around that time, the Midwest Pages to Prisoners Project – an organization that sends free books to people who are incarcerated – received many letters like this:
“The prison I am at has us on 23 hour a day lockdown due to the coronavirus threat. We also lost access to most jobs around the prison, visits, library, and a lot of other things that help relieve stress, like sports, walking track, weight-lifting, church, etc.
So books will be a huge help, we are three-deep to a cell and I can’t say I always enjoy the company.”
And also –a la Baudelaire’s “oasis of horror in a desert of boredom” – we received some terrifying stories from people who got very sick:
“On Sept 1st I was Covid-positive, on Sept 4 shortly after 6 a.m. I was rushed to the hospital. I was on a ventilator & in paralytic coma for 6 ½ days. Both lungs free of pneumonia, I have now been diagnosed with stress-induced cardiomyopathy due to Covid. I am back at the prison. My voice sounds like a man (LOL).”
There are almost always communicable diseases circulating through the jails and prisons. That’s certainly still been true during the Covid-19 pandemic: in southern Indiana, vaccine uptake is relatively low, especially among the population of people usually targeted for incarceration. Still, volunteers began visiting the jail again as soon as we were allowed – during stressful times, people need more support and kindness than usual, not less.
For the past few months, the administration has been letting us bring equipment to record people reading books for their kids. Then librarians at our excellent local library send the video and a paper copy of the book to the person’s kids.
After a Sunday morning recording session, someone was telling me a bit about her recent experience:
“We’ve got three levels of security in the women’s block right now, so we’re on lockdown about 22 hours a day. They only let us out to the common area one level at a time.”
“Breakfast at 4:30, why I was feeling a sleepy. They do have coffee at commissary, instant coffee. Commissary’s a little tough, the prices of everything have gone up but they didn’t raise the weekly cap, so you can get a little less each week. My parents have been putting money in my commissary, but you can’t do more than the cap.”
“My parents have been taking good care of me, thank God, not that I deserve it.”
Which always breaks my heart to hear somebody say. She deserves help. We all do.
I doubt there’s anyone among us who would be pleased to have people always associate us with the worst things we’d ever done. Or have our worst moments mulled over by judges and prosecutors and public defenders, then written up in someone else’s words and stored in a permanent file.
I’ve certainly done bad things & broken laws: I had the good fortune to not be caught. (Good fortune, plus pale skin, masculine frame, upper-class accent, apartments in wealthy, less-policed areas …) I drove with drugs in my car. And I definitely hurt people – started petty arguments, callously trampled feelings – in ways that aren’t illegal, but I’d still feel awful having those moments replayed again and again, discussed in a courtroom, treated as though those smallest, meanest moments were the essence of me, the most important thing for somebody to know about me.
In Just Mercy, lawyer Bryan Stevenson writes that:
“I thought of the victims of violent crime and the survivors of murdered loved ones, and how we’ve pressured them to recycle their pain and anguish and give it back to the offenders we prosecute. I thought of the many ways we’ve legalized vengeful and cruel punishments, how we’ve allowed our victimization to justify the victimization of others.”
“But simply punishing the broken – walking away from them or hiding them from sight – only ensures that they remain broken and we do, too. There is no wholeness outside of our reciprocal humanity.”
“I frequently had difficult conversations with clients who were struggling and despairing over their situations – over the things they’d done, or had been done to them, that had led them to painful moments. Whenever things got really bad, and they were questioning the value of their lives, I would remind them that each of us is more than the worst things we’ve ever done.”
“I told them that if someone tells a lie, that person is not just a liar. If you take something that doesn’t belong to you, you are not just a thief.”
In jail that day, I tried to say something vaguely similar. But at the end of our recording session, I got to return to my loving family. I got to read a book to my children while hugging them.
She went back to the block, waiting for us to mail a DVD of her reading & a copy of the book to her kids. Which isn’t the same, and isn’t enough.
Public education is almost always contentious in this country: Evolution! The pledge of allegiance! The Founding Fathers’ complicity in felonious (oft murderous) abduction & torture!
Now, we’re also arguing over whether it’s safe for schools to be open at all!
At the school board meeting, a white woman stood up at the podium, ripped off her mask, and said “I can’t breathe.”
(Unfortunately, I assume the resonance with the BLM protests was intentional. When I went to pick up my kids from school last week, a white mother was wearing a t-shirt with the traditional white on black BLM layout that said “Drunk Wives Matter.” My hometown is within a half hour’s drive of the national KKK headquarters.)
As is the way of things in our country right now, about half the parents in attendance were aghast. The other half cheered.
“The masks don’t work! Everybody knows the masks don’t work!” people shouted.
Oddly enough, though, the people saying “the masks don’t work” are actually correct. But so are the people who say that masks work. The word “work” is pretty nebulous!
As Joseph Allen & Helen Jenkins wrote in a recent New York Times editorial, many well-meaning people have been unhelpfully vague when defining goals for our pandemic response. Are we trying to minimize lifelong harms from all causes? Are we trying to minimize the number of deaths that occur this year? Are we trying to eradicate the virus that causes Covid-19?
Each of these goals would require that we take a different set of actions.
Masks “work” in the sense that when people are wearing face masks, there’s a lower probability of Covid-19 transmission during any interaction.
Masks reduce the number of viral particles that exit a person’s airspace as they speak or exhale. Of course, this presupposes that the person wearing a mask actually is shedding viral particles. But that’s the tricky thing about Covid-19 (or influenza)! Some people feel fine!
Masks also might reduce the likelihood of transmission when an unexposed person who is hoping to avoid or delay illness wears a mask. (Masks probably help with this, but it’s less well tested.)
Universal mask requirements are a great tool to delay transmission!
When worn selectively – for instance, only during hospital visits, or only when inside nursing homes – masks can also skew the demographics of transmission. With Covid-19, skewing the demographics of transmission is a great goal!
Even back before we had safe, effective vaccines, we could’ve saved huge numbers of lives by skewing the demographics of transmission! Some people are much more likely to recover from Covid-19 safely than others! (Major risk factors include advanced age, diabetes status, and probably smoking status. But there are also unknown risk factors – we don’t know why certain young healthy people can get so sick from this.)
Masks don’t “work,” though, if the goal is to prevent cases of Covid-19.
By May of 2020, it was already clear that Covid-19 would become endemic. We’d spread the virus too widely by then. The virus will never go away. Cases will never fall to zero.
Everyone alive today, and everyone born in the future, will be exposed to Covid-19 eventually. (With the possible exception of people who happen to die of other causes within the next few years.)
There’s still a strong argument for using masks to delay Covid-19 transmission: with more time, more people can be vaccinated! The vaccines work, by which I mean that the vaccines save lives.
Everyone will be exposed to Covid-19! The people who have been vaccinated are much more likely to survive! This front page article in my local newspaper is fear mongering; it’s a sort of fear mongering that I wholeheartedly endorse!
Vaccination is a safe, effective, time-tested medical practice. The principles behind vaccination were independently discovered centuries ago by scientists and healers in Africa, India, and China. Their discoveries were the basis for Edward Jenner’s smallpox vaccine.
When scientists say that vaccines “work” – vaccines save lives – we mean something very different than when we say that masks “work” – masks delay exposure!
In conjunction with vaccination, masks can be helpful!
Which is why the argument that children should currently wear masks in school is reasonable. Covid-19 tends not to be very dangerous for children, but occasionally it’s deadly. There’s a definite cost to wearing masks in school – muffled voices, hidden facial expressions, increased hassle – but children could be kept safer by delaying their exposure to Covid-19 until after a vaccine is approved for them.
(I feel lucky that my kids have already safely recovered from Covid-19 – I’m not beset by the same fear over this that other parents are navigating. But I understand their concern: raising children often feels terrifying because my heart would shatter if anything happened to these tiny, willful, fragile creatures.)
Most of the people who say “masks don’t work” are planning not to get the Covid-19 vaccine. Which means, weirdly, that they’re right! Without the end goal of eventual vaccination, masks don’t work! Even if universal masking policies were kept in place forever, Covid-19 is so infectious that everyone would still be exposed eventually!
The vaccines can save lives; masks cannot.
Obviously, I’m not arguing that you should ignore local mask requirements: I’m currently wearing a face mask as I type this! And there are lots of people who do want to be vaccinated who don’t have access yet – this isn’t much of an issue for adults in the United States, but vaccine access is an incredible privilege for most of the world’s population.
Because Covid-19 can be transmitted by people who feel fine, wearing a mask is a way to protect others. And personal preference isn’t a good reason to endanger the lives of the folks around us! That’s why we have traffic laws! Even if I think it’d be fun to go out driving while buzzed on booze, or to cruise on the left-hand side of the road, I shouldn’t be allowed to do it!
But also, I think it’s worth acknowledging that, within the full context of their actions, people’s denunciations of masks are actually scientifically accurate.
“Follow the science” is an unhelpful slogan – scientific analysis doesn’t result in a monolithic set of inarguable conclusions. At the heart of any policy, there are goals and priorities. These are set by philosophical or ethical considerations, not scientific fact.
“Follow the scientific findings that help us all achieve my goals for the world” doesn’t have the same pithy ring to it, though.
For people whose past cultural experiences have led them to associate mint smells with sweet tastes, pairing the scent of mint with a sip of sucrose solution makes them believe that the drink is more sugary than it really is. When mint scent is paired with a sip of mildly acidic water, the drink seems less sour than it really is.
This experiment didn’t assess people’s perception of alcoholic drinks, but people in the United States probably make the same mistake about the bourbon in a mint julep.
Our assumptions – particular to our own cultural experience of the world – can powerfully deceive us.
A mint julep mixed perfectly for someone from the United States would taste bitter to someone from Vietnam.
Viet Thanh Nguyen – author of The Sympathizer, which I’ve written about previously – strives to draw attention to our cultural blindness. The way our minds’ innate self-deceptions allow us to overlook or misinterpret the experiences of others.
My spouse and I have often felt grateful for Nguyen’s work. His essay about the sinking sensation he felt after teaching his child to read was particularly beautiful. (I linked to it in my own essay about teaching a child to read.)
Which is why we felt so dismayed by Nguyen’s most recent New York Times editorial.
Nguyen explains why he enjoys teaching over Zoom. He’s prompted with students’ names; he can see their reactions up close; student voices contribute to the lecture from the same up-front position of power as his own; typed remarks can overlap without distracting; lectures are recorded for students to review later.
All well and good. Nguyen is quite intelligent. If he thinks Zoom is good for lectures, I’m inclined to believe him.
But lectures aren’t the best way to learn.
For many subjects, project-based learning is a more effective way to educate students. Many of my spouse’s resources – designed primarily for teaching college-level biology and introductory Earth & space science with a social justice bent – are available on her website, here.
For the better part of a decade, I’ve hosted a poetry class in the county jail. We read poems and discuss how they make us feel. Our discussions touch upon contemporary scientific research, mythology, economics – all safe enough topics, for most folks – but also religion, addiction, trauma, violence, relationships, loss – which can be tough for anyone to talk about, let alone a room full of men who won’t get to see their families for months.
Because people cycle through the county jail, I never know who will be coming to class each week until I get there. For a few months, I might be with mostly the same group of men. Other weeks, I won’t have met any of the dozen or so people previously.
And there’s a huge difference between what we can accomplish – between what sorts of things feel safe to discuss – when the people in class haven’t met me before, and haven’t been in a class like that with each other. If we haven’t built the necessary emotional connection, we can do less. The class is worse for all of us.
Recently, the jail has allowed a small number of classes over Zoom. But Zoom doesn’t let you make the same emotional connection.
People sometimes complain about the supposed invasiveness of Zoom – the camera snatches up your personal surroundings, the pictures on your wall, the books on your shelves, your family in the background – but it’s by no means the intimacy of being there.
My spouse says, “Over Zoom you can’t tell who’s hungry.”
It would be nice if she meant this metaphorically – that it’s hard to tell who’s eager to learn. But, no. Many students aren’t eating enough. They are hungry.
Worse, we read Nguyen’s paean to Zoom on a snow day.
Streets near my spouse’s high school school were well-salted and plowed, but we live in a sprawling, semi-rural area – the school district serves families from a mix of socioeconomic backgrounds. There are hills and valleys – not everyone can get a satellite signal at home. And the for-profit cable companies certainly haven’t connected those families to the modern world with wires.
Still, the pandemic has made “e-learning days” seem like a reliable alternative. If it snows, kids learn from home.
“What’s Zoom supposed to do,” my spouse asked, “for my students with no heat?”
This isn’t (only) a concern for fluke events like the avarice-fueled power outages and heat losses in Texas. My spouse grew up in Albany, New York. Every winter was cold. The infrastructure to heat homes there was secure – for children whose families had money.
My spouse’s family didn’t. Her father failed to pay the electric bill. The power was shut off. And then the district called a snow day.
If my spouse and her sibling had gone to school, it wouldn’t have been so bad. Warm classrooms, a hot meal.
Instead they were stuck at home, shivering. Wanting so badly to go to a neighbor’s house. But then the neighbors would know.
In the United States, where poverty is often stigmatized as a moral failing, people hide the ache of want.
Which is why Zoom is so horrible. Zoom makes it easy. When you only have to disguise a small corner of your life, you can convey the illusion that things are okay.
Elizabeth Kolbert’s lovely essay in the New York Review of Books, “Chemical Warfare’s Home Front,” describes Fritz Haber’s contribution to the use of toxic gas in war.
Haber orchestrated the use of chlorine to suffocate all animal life – including soldiers – downwind of his nation’s troops. And his plan succeeded. After unleashing 300,000 pounds of chlorine gas, huge numbers of people died. Soldiers– some of whom suffocated, some whose lungs burned, some who committed suicide when enveloped by the gas – as well as horses, cows, chickens, wildlife.
Chemical warfare is horrible, but Haber’s battlefield “experiment” was considered a success. Military researchers then concocted more dangerous chemical agents, like DNA-crosslinking mustard gas and muscle-clenching Sarin nerve gas.
Fritz Haber’s other ideas were seemingly more beneficial for humanity. Haber was awarded the Nobel Prize in chemistry for making synthetic fertilizer.
Synthetic fertilizer let us grow more crops.
We could feed billions more people!
The global population soared.
If we hadn’t invented synthetic fertilizer, the global population would still be under four billion people.
Climate change would still be a huge problem – the most outrageous polluters haven’t been the most populous nations. Climate change was caused primarily by the United States and other wealthy nations, whereas overpopulation will first devastate equatorial nations.
A seemingly good idea – more fertilizer! – has greatly exacerbated the scale of suffering.
Kolbert discusses the invention of chlorofluorocarbons, which seemed like great coolants. With CFCs, Frigidaire could build cheaper refrigerators! Regular families could keep their ice cream cold without spending as much on electricity.
Unfortunately, CFCs also dissolve our ozone layer. More dangerous ultraviolet radiation began to reach us from the sun, causing horrible skin cancers.
CFCs seemed like a good idea — they do work great as coolants — but they caused awful problems as part of a bigger system.
Kolbert quotes the chemist F. Sherwood Rowland, who said, in reference to his studies of CFCs, “The work is going very well, but it looks like the end of the world.”
Anthropologist Joseph Tainter argued civilizations collapse when overwhelmed by complexity.
Like the children’s nursery rhyme about the old lady who swallowed a fly — then a spider to catch the fly, then a cat to catch the spider — our complicated solutions can create new, perhaps worse, problems.
This is the theme of Jenny Kleeman’s Sex Robots and Vegan Meat. Kleeman investigates several industries that purport to solve our world’s problems – You can eat meat without killing animals! You can make a baby without a mother’s body! – without addressing the fundamental causes of these problems.
Describing her travels, Kleeman writes:
I head back to my hotel as the reassuring cloak of darkness falls on Las Vegas. I’m exhausted. Music is thumping out of huge speakers mounted on the building’s exterior: throbbing, pounding beats that are supposed to entice gamblers into the hotel’s casino. I wipe my key card and flop down on the giant bed.
On the bedside table, there’s a metal dish full of individually wrapped pairs of earplugs: wax ones, foam ones, silicone ones – a profusion of solutions supplied by the management to the noise pollution problem caused by the management.
They could just switch the music off, of course, but they have provided a little piece of technology instead so they don’t have to.
My head is full of Eva, [a prototype interactive sex doll] who has the body of a real woman, but can be beaten without feeling a thing. Rather than dealing with the cause of a problem, we invent something to try to cancel it out.
Perhaps we should eat different foods. Perhaps our attitudes about sex or the importance of a sociable community are making our lives worse. Perhaps if we addressed these issues directly, we wouldn’t need sex robots or vegan meat.
Clean meat is one of many possible futures of food, so long as we continue to eat meat. We will always have the power to not want it anymore, or to want it much less.
That is where the real power lies: in harnessing our desires, rather than in mastering technology. Until we do, we will be even further removed from where our food comes from, and will feel even less responsible for it.
We will be perpetuating the kind of thinking that caused the meat mess in the first place.
In April 2020, I described two major drawbacks to our efforts to “slow the spread” of Covid-19 instead of providing targeted protection for the people at high risk of severe illness.
2.) Each infection encompasses some number of viral replications and thus genetic drift. If a population of 20 people transfers a virus between themselves one by one, rather than all catching it from the same initial carrier, the virus has 20-fold more generations to mutate and better evade our immune systems.
Admittedly, my April 2020 prediction about the timeline for vaccine development was quite wrong – I thought this might take three to five years. I’m thankful that I was wrong. I’m obviously grateful for the fantastic work done by vaccine developers so far.
For these vaccines to effectively staunch viral transmission, we’ll need to vaccinate large numbers of people – immunity from prior infections won’t necessarily help much because immunity to this particular virus lapses so quickly, and because people’s prior infections were staggered in time. (Indeed, we’ll probably need to vaccinate large numbers of people repeatedly, because some of our data suggests that vaccine-derived immunity to this also lapses on a timescale of months.)
Unfortunately, we live in a country where large numbers of people distrust the medical establishment. Even if we had sufficient doses of the vaccines available today, I don’t know what percentage of our population would choose to get them.
Masks definitely reduce viral transmission. It was obviously a good idea for everyone to wear masks anywhere that high risk and lower risk people share the same space.
Cooperation definitely makes for a better place to live. In places that enacted mask orders, it’s obviously a good idea to follow them.
It’s worth remembering, though, that any fix – even something as simple as this piece of cloth covering my nose and mouth – can have unintentional consequences. New virus variants – which our current vaccines may be less effective against – are a predictable result of our effort to “slow the spread” with masks.
I volunteer with Pages to Prisoners, an organization that sends free books to people who are incarcerated. We’ve included a sheet of information about Covid-19 with each package recently, helping to explain that Covid-19 is not a hoax, that it’s a dangerous respiratory disease, that masks and social distancing can help people reduce their risk.
I’m currently revising this information sheet – it was put together months ago, when we understood less about this virus – and I’m still recommend that everyone wear masks.
Not just because prisons are places where many low risk and high risk people are confined together — although, they are. Outrageous sentencing practices have led to a large number of elderly people being stuck in prison.
But also, anecdotal evidence suggests that people are more likely to develop severe illness from Covid-19 when they are exposed to a large number of viral particles at once.
Viruses reproduce exponentially – you can get sick if you inhale even one capsid. But you’re more likely to get seriously ill if you inhale a whole bunch of viral particles. If you’re initially exposed to a small number of particles, your body will have more time to fight off the infection before it makes you feel sick.
Research studies from military bases have shown that Covid-19 will continue to spread even when everyone wears masks and tries to stay six feet away from each other. But we haven’t tested – an experiment like this would be totally unethical – whether we’re more likely to see asymptomatic or mild cases when people’s initial exposure is to a small number of viral particles.
It’s quite likely, though.
So, although I think our efforts to “slow the spread” weren’t the best plan last year, I’ll still be recommending masks.
From Emily Cox’s recent article in Bloomington, Indiana’s Herald Times:
[Scot Moore, a medical doctor on our school district’s Covid-19 metrics committee] said since the school year started, there have been zero pediatric admissions to IU Health Bloomington Hospital for Covid-19.
“Over the same time, I think it’s important to point out that we’ve admitted now 29 adolescents with intended or attempted suicide, which is 10 times what we do usually,” Moore said.
Many cite isolation and academic stress as factors for their decisions, he said.
Moore also said he thinks the [Covid-19] transmission rate in the schools is about zero.
Depression nearly killed me once, and it’s killed friends and neighbors and people I went to school with. The only thing that saved me was the knowledge that at some point my life had ceased to be my own property and had become the property of the people who loved me.
Although there’s not enough love in the world, chances are that somebody loves you, and you shouldn’t decide to kill yourself without consulting the person or persons doing the loving. The voice of your depression is going to tell you that they don’t love you, but you should ask them if that’s true. If they say they love you, believe them and stay alive for them.
From Gerry Duggan’s and Ian Doescher’s Deadpool #21 (which I’ve written about previously, here):
A young woman is standing at the ledge of a building. Deadpool tries to cheer him up, but his gallows humor only upsets her more. “What’s your problem?” she demands.
But then he takes her on an adventure …
… and, in a beautiful depiction of real-life heroism, Deadpool drives her to the hospital.
This is a hard time of year.
If you’re living in the Northern Hemisphere, the sun won’t stay up long enough. Then there are the holidays – even in the best of years, many people find they can’t muster up the joy and enthusiasm that seems expected of them.

There’s broad scientific consensus that school closures hurt children, probably making a significant contribution to future increases in premature death.
There’s also broad scientific consensus that school closures – particularly elementary school closures – aren’t helpful in slowing the spread of Covid-19. Children aren’t major vectors for this virus. Adults just have to remember not to congregate in the teachers’ lounge.
Worldwide, a vanishingly small percentage of viral transmissions have occurred inside schools.
And … our district just closed in-person school for all children.
In-person indoor dining at restaurants is still allowed. Bars are still open.
Older people are sending a clear message to kids: “Your lives matter less than ours.”
For at-risk children, school closures are devastating. A disruption in social-emotional learning; lifelong education gaps; skipped meals.
But for my (privileged!) family, the closure will be pretty nice. I was recently feeling nostalgic about the weeks in August when my eldest and I spent each morning together.
Our youngest attends pre-K at a private school. Her school, like most private schools around the country, (sensibly) re-opened on time and is following its regular academic calendar.
My eldest and I will do two weeks of home schooling before winter break. And it’ll be fun. I like spending time with my kids, and my eldest loves school so much that she often uses up most of her energy during the day – teachers tell us what a calm, lovely, hard-working kid she is. And then she comes home and yells, all her resilience dissipated.
Which is normal! Totally normal. But it’s a little crummy, as a parent, to know you’ve got a great kid but that you don’t get to see her at her best.
Right now she’s sad about not going to school – on Monday, she came home crying, “There was an announcement that we all have to switch to online only!” – but I’m lucky that I can be here with her. Writing stories together, doing math puzzles, cooking lunch.
Maybe we’ll practice magic tricks. She loves magic.
Last month, I was getting ready to drive the kids to school. T. (4 years old) and I were in the bathroom. I’d just handed T. her toothbrush.
N. (6 years old) walked over holding a gallon-sized plastic bag.
“Father, do you want to see a magic trick?” she asked.
“Okay, but I have to brush my teeth while you’re doing it.”
“Okay,” she said, and opened the bag. She took out a multi-colored lump of clay. It was vaguely spherical. Globs of red, white, and blue poked up from random patches across the surface, as though three colors of clay had been haphazardly moshed together.
“So you think this is just this,” she said, but then …”
She took out a little wooden knife and began sawing at the lump. “This is just this?”, I wondered. It’s an interesting phrase.
Her sawing had little effect. The knife appeared useless. I’m pretty sure this wooden knife is part of the play food set she received as a hand-me-down when she was 9 months old. “Safe for babies” is generally correlated with “Useless for cutting.”
She was having trouble breaking the surface of her lump.
I spat out my toothpaste.
She kept sawing. She set down the knife and stared at the clay intently. A worthy adversary.
I stood there, watching.
She grabbed the knife again and resumed sawing. More vigorously, this time. She started stabbing, whacking. This was enough to make a tiny furrow. She tossed aside the knife and pulled with her fingertips, managing to pry two lobes of the strange lump away from each other.
“Okay,” she said, “it’s hard to see, but there’s some green in there.”
T. and I crouched down and peered closely. Indeed, there was a small bit of round green clay at the center of the lump.
“Wow!” exclaimed T. “I thought it was just a red, and, uh, blue, and white ball! But then, on the inside, there’s some green!”
“I know!” said N., happy that at least one member of her audience understood the significance of her trick. “And look, I might even get it back together!”
N. started performing magic when she was four. T. was asleep for her afternoon nap.
“Okay,” she said, “you sit there, and I’ll put on a magic show. Watch, I’ll make, um … this cup! See this cup? I’ll make it disappear.”
“Okay,” I said, curious. We’d just read a book that explained how to make a penny disappear from a glass cup – the trick is to start with the cup sitting on top of the penny, so that the coin looks like it’s inside the cup but actually isn’t.
I had no idea how she planned to make the cup itself disappear.
“Okay, so, um, now you’re ready, and …” she looked at the cup in her hands. Suddenly, she whisked it behind her back. And stood there, looking at me somberly, with her hands behind her back.
“I don’t have it,” she said.
Magic – convincing an audience to believe in an illusion.
Our species is blessed with prodigious longevity, probably because so many grandmothers among our ancestors worked hard to help their grandchildren survive.
(The long lives of men are probably an accidental evolutionary byproduct, like male nipples or female orgasms. Elderly men, with their propensity to commandeer resources and start conflicts, probably reduced the fitness of their families and tribes.)
After we reach our seventies, though – when our ancestors’ grandchildren had probably passed their most risky developmental years – our bodies fail. We undergo immunosenescence – our immune systems become worse at suppressing cancer and infections.
We’re fast approaching flu season, which is especially harrowing this year.
We, as a people, have struggled to respond to this calamity. We have a lot of scientific data about Covid-19 now, but science is never value-neutral. The way we design experiments reflects our biases; the way we report our findings, even more so.
For example, many people know the history of Edward Jenner inventing the world’s first vaccine. Fewer are aware of the long history of inoculation in Africa (essentially, low-tech vaccination) that preceded Jenner’s work.
So it’s worthwhile taking a moment to consider the current data on Covid-19.
Data alone can’t tell us what to do – the course of action we choose will reflect our values as a society. But the data may surprise a lot of people – which is strange considering how much we all feel that we know about Covid-19.
Indeed, we may realize that our response so far goes against our professed values.
Spoiler: I think we shouldn’t close in-person school.
Since April, I’ve written severalessays about Covid-19. In these, I’ve made a number of predictions. It’s worthwhile to consider how accurate these predictions have been.
This, after all, is what science is. We use data to make an informed prediction, and then we collect more data to evaluate how good our prediction was.
Without the second step – a reckoning with our success or failure – we’re just slinging bullshit.
I predicted that our PCR tests were missing most Covid-19 infections, that people’s immunity was likely to be short-lived (lasting for months, not years), and that Covid-19 was less dangerous than seasonal influenza for young people.
In my essays, I’ve tried to unpack the implications of each of these. From the vantage of the present, with much more data at our disposal, I still stand by what I’ve written.
But gloating’s no fun. So I’d rather start with what I got wrong.
My initial predictions about Covid-19 were terrible.
I didn’t articulate my beliefs at the time, but they can be inferred from my actions. In December, January, and February, I made absolutely no changes to my usual life. I didn’t recommend that travelers be quarantined. I didn’t care enough to even follow the news, aside from a cursory glance at the headlines.
While volunteering with the high school running team, I was jogging with a young man who was finishing up his EMT training.
“That new coronavirus is really scary,” he said. “There’s no immunity, and there’s no cure for it.”
I shrugged. I didn’t know anything about the new coronavirus. I talked with him about the 1918 influenza epidemic instead.
I didn’t make any change in my life until mid-March. And even then, what did I do?
I called my brother and talked to him about the pizza restaurant – he needed a plan in case there was no in-person dining for a few months.
My next set of predictions were off, but in the other direction – I estimated that Covid-19 was about four-fold more dangerous than seasonal influenza. The current best estimate from the CDC is that Covid-19 is about twice as dangerous, with an infection fatality ratio of 0.25%.
But seasonal influenza typically infects a tenth of our population, or less.
We’re unlikely to see a significant disruption in the transmission of Covid-19 (this is the concept of “herd immunity”) until about 50% of our population has immunity from it, whether from vaccination or recovery. Or possibly higher – in some densely populated areas, Covid-19 has spread until 70% (in NYC) or even 90% (in prisons) of people have contracted the disease.
Population density is hugely important for the dynamics of Covid-19’s spread, so it’s difficult to predict a nation-wide threshold for herd immunity. For a ballpark estimate, we could calculate what we’d see with a herd immunity threshold of about 40% in rural areas and 60% in urban areas.
Plugging in some numbers, 330 million people, 80% urban population, 0.25% IFR, 60% herd immunity threshold in urban areas, we’d anticipate 450,000 deaths.
That’s about half of what I predicted. And you know what? That’s awful.
Each of those 450,000 is a person. Someone with friends and family. And “slow the spread” doesn’t help them, it just stretches our grieving to encompass a whole year of tragedy instead of a horrific month of tragedy.
Based on the initial data, I concluded that the age demographics for Covid-19 risk were skewed more heavily toward elderly people than influenza risk.
I may have been wrong.
It’s difficult to directly compare the dangers of influenza to the dangers of Covid-19. Both are deadly diseases. Both result in hospitalizations and death. Both are more dangerous for elderly or immunocompromised people, but both also kill young, healthy people.
Typically, we use an antigen test for influenza and a PCR-based test for Covid-19. The PCR test is significantly more sensitive, so it’s easier to determine whether Covid-19 is involved a person’s death. If there are any viral particles in a sample, PCR will detect them. Whereas antigen tests have a much higher “false negative” rate.
Instead of using data from these tests, I looked at the total set of pneumonia deaths. Many different viruses can cause pneumonia symptoms, but the biggest culprits are influenza and, in 2020, Covid-19.
So I used these data to ask a simple question – in 2020, are the people dying of pneumonia disproportionately more elderly than in other years?
I expected that they would be. That is, after all, the prediction from my claims about Covid-19 demographic risks.
For people under the age of 18, we’ve seen the same number of deaths (or fewer) in 2020 as in other years. The introduction of Covid-19 appears to have caused no increased risk for these people.
But for people of all other ages, there have been almost three times as many people dying of these symptoms in 2020 compared to other years.
In most years, one thousand people aged 25-34 die of these symptoms; in 2020, three thousand have died. In most years, two thousand people aged 35-44 die of these symptoms; in 2020, six thousand have died. This same ratio holds for all ages above eighteen.
Younger people are at much less risk of harm from Covid-19 than older people are. But, aside from children under the age of eighteen, they don’t seem to be exceptionally protected.
Of course, my predictions about the age skew of risk might be less incorrect than I’m claiming here. If people’s dramatically altered behavior in 2020 has changed the demographics of exposure as compared to other years – which is what we should be doing to save the most lives – then we could see numbers like this even if Covid-19 had the risk skew that I initially predicted.
I predicted that four or more years would pass before we’d be able to vaccinate significant numbers of people against Covid-19.
I sure hope that I was wrong!
We now know that it should be relatively easy to confer immunity to Covid-19. Infection with other coronaviruses, including those that cause common colds, induce the production of protective antibodies. This may partly explain the low risk for children – because they get exposed to common-cold-causing coronaviruses so often, they may have high levels of protective antibodies all the time.
Several pharmaceutical companies have reported great results for their vaccine trials. Protection rates over 90%.
So the problem facing us now is manufacturing and distributing enough doses. But, honestly, that’s the sort of engineering problem that can easily be addressed by throwing money at it. Totally unlike the problem with HIV vaccines, which is that the basic science isn’t there – we just don’t know how to make a vaccine against HIV. No amount of money thrown at that problem would guarantee wide distribution of an effective vaccine.
We will still have to overcome the (unfortunately significant) hurdle of convincing people to be vaccinated.
For any individual, the risk of Covid-19 is about twice the risk of seasonal influenza. But huge numbers of people choose not to get a flu vaccine each year. In the past, the United States has had a vaccination rate of about 50%. Here’s hoping that this year will be different.
Which means that elderly people will always be at risk of dying from Covid-19.
The only way to protect people whose bodies have gone through “age-related immunosenence” – the inevitable weakening of an immune system after a person passes the evolutionarily-determined natural human lifespan of about 75 years – will be to vaccinate everybody else.
Depending on how long vaccine-conferred immunity lasts, we may need to vaccinate people annually. I worry, though, that it will become increasingly difficult to persuade people to get a Covid-19 vaccine once the yearly death toll drops to influenza-like levels – 50,000 to 100,000 deaths per year in the United States.
(Note: you may have seen articles in the New York Times suggesting that we’ll have long-lasting protection. They’re addressing a different question — after recovery, or vaccination, are you likely to become severely ill with Covid-19? And the answer is “probably not,” although it’s possible. When I discuss immunity here, I mean “after recovery, or vaccination, are you likely to be able to spread the virus after re-infection?” And the answer is almost certainly “yes, within months.”)
And I wrote about the interplay between short-lived immunity and the transmission dynamics of an extremely virulent, air-born virus.
This is what the Harvard public health team got so wrong. When we slow transmission enough that a virus is still circulating after people’s immunity wanes, they can get sick again.
For this person, the consequences aren’t so dire – an individual is likely to get less sick with each subsequent infection by a virus. But the implications for those who have not yet been exposed are horrible. The virus circulates forever, and people with naive immune systems are always in danger.
It’s the same dynamics as when European voyagers traveled to the Americas. Because the European people’s ancestors lived in unsanitary conditions surrounded by farm animals, they’d cultivated a whole host of zoogenic pathogens (like influenza and this new coronavirus). The Europeans got sick from these viruses often – they’d cough and sneeze, have a runny nose, some inflammation, a headache.
In the Americas, there were fewer endemic diseases. Year by year, people wouldn’t spend much time sick. Which sounds great, honestly – I would love to go a whole year without headaches.
But then the disgusting Europeans reached the Americas. The Europeans coughed and sneezed. The Americans died.
And then the Europeans set about murdering anyone who recovered. Today, descendants of the few survivors are made to feel like second-class citizens in their ancestral homelands.
In a world with endemic diseases, people who have never been exposed will always be at risk.
That’s why predictions made in venues such as the August New York Times editorial claiming that a six- to eight-week lockdown would stop Covid-19 were so clearly false. They wrote:
Six to eight weeks. That’s how long some of the nation’s leading public health experts say it would take to finally get the United States’ coronavirus epidemic under control.
For proof, look at Germany. Or Thailand. Or France.
Obviously, this didn’t work – in the presence of an endemic pathogen, the lockdowns preserved a large pool of people with naive immune systems, and they allowed enough time to pass that people who’d been sick lost their initial immunity. After a few months of seeming calm, case numbers rose again. For proof, look at Germany. Or France.
Case numbers are currently low in Thailand, but a new outbreak could be seeded at any time.
And the same thing is currently happening in NYC. Seven months after the initial outbreak, immunity has waned; case numbers are rising; people with mild second infections might be spreading the virus to friends or neighbors who weren’t infected previously.
All of which is why I initially thought that universal mask orders were a bad idea.
We’ve known for over a hundred years that masks would slow the spread of a virus. The only question was whether slowing the spread of Covid-19 would cause more people to die of Covid-19.
And it would – if a vaccine was years away.
But we may have vaccines within a year. Which means that I may have been wrong. Again, the dynamics of Covid-19 transmission are still poorly understood – I’ll try to explain some of this below.
In any case, I’ve always complied with our mask orders. I wear a mask – in stores, at school pickup, any time I pass within six feet of people while jogging.
To address global problems like Covid-19 and climate change, we need global consensus. One renegade polluting wantonly, or spewing viral particles into the air, could endanger the whole world. This is precisely the sort of circumstance where personal freedom is less important than community consensus.
The transmission dynamics of Covid-19 are extremely sensitive to environment. Whether you’re indoors or outdoors. How fast the air is moving. The population density. How close people are standing. Whether they’re wearing masks. Whether they’re shouting or speaking quietly.
Because there are so many variable, we don’t have good data. My father attended a lecture and a colleague (whom he admires) said, “Covid-19 is three-fold more infectious than seasonal influenza.” Which is bullshit – the transmission dynamics are different, so the relative infectivity depends on our behaviors. You can’t make a claim like this.
It’s difficult to measure precisely how well masks are slowing the spread of this virus.
But here’s a good estimate: according to Hsiang et al., the number of cases of Covid-19, left unchecked, might have increased exponentially at a rate of about 34% per day in the United States.
That’s fast. If about 1% of the population was infected, it could spread to everyone within a week or two. In NYC, Covid-19 appear to spread to over 70% of the population within about a month.
(To estimate the number of infections in New York City, I’m looking at the number of people who died and dividing by 0.004 – this is much higher than the infection fatality rate eventually reported by the CDC, but early in the epidemic, we were treating people with hydroxychloraquine, an unhelpful poison, and rushing to put people on ventilators. We now know that ventilation is so dangerous that it should only be used as a last resort, and that a much more effective therapy is to ask people to lie on their stomachs – “proning” makes it easier to get enough oxygen even when the virus has weakened a person’s lungs.)
Masks dramatically slow the rate of transmission.
A study conducted at a military college – where full-time mask-wearing and social distancing were strictly enforced – showed that the number of cases increased from 1% to 3% of the population over the course of two weeks.
So, some math! Solve by taking ten to the power of (log 3)/14, which gives an exponential growth rate of 8% per day. Five-fold slower than without masks.
But 8% per day is still fast.
Even though we might be able to vaccinate large numbers of people by the end of next year, that’s not soon enough. Most of us will have been sick with this – at least once – before then.
I don’t mean to sound like a broken record, but the biggest benefit of wearing masks isn’t that we slow the rate of spread for everyone — exponential growth of 8% is still fast — but that we’re better able to protect the people who need to be protected. Covid-19 is deadly, and we really don’t want high-risk people to be infected with it.
I’ve tried to walk you through the reasoning here — the actual science behind mask policies — but also, in case it wasn’t absolutely clear: please comply with your local mask policy.
You should wear a mask around people who aren’t in your (small) network of close contacts.
I’m writing this essay the day after New York City announced the end of in-person classes for school children.
A major problem with our response to Covid-19 is that there’s a time lag between our actions and the consequences. Human brains are bad at understanding laggy data. It’s not our fault. Our ancestors lived in a world where they’d throw a spear at an antelope, see the antelope die, and then eat it. Immediate cause and effect makes intuitive sense.
Delayed cause and effect is tricky.
If somebody hosts a party, there might be an increase in the number of people who get sick in the community over the next three weeks. Which causes an increase in the number of hospitalizations about two weeks after that. Which causes people to die about three weeks after that.
There’s a two-month gap between the party and the death. The connection is difficult for our brains to grasp.
As a direct consequence, we’ve got ass-hats and hypocrites attending parties for, say, their newly appointed Supreme Court justice.
But the problem with school closures is worse. There’s a thirty year gap between the school closure and the death. The connection is even more difficult to spot.
The authors link two sets of existing data: the correlation between school closures and low educational achievement, and the correlation between low educational achievement and premature death.
The public debate has pitted “school closures” against “lives saved,” or the education of children against the health of the community. Presenting the tradeoffs in this way obscures the very real health consequences of interrupted education.
These consequences are especially dire for young children.
The authors calculate that elementary school closures in the United States might have (already!) caused 5.5 million years of life lost.
Hsiang et al. found that school closures probably gave us no benefit in terms of reducing the number of Covid-19 cases, because children under 18 aren’t significant vectors for transmission (elementary-aged children even less so), but even if school closures had reduced the number of Covid-19 cases, closing schools would have caused more total years of life to be lost than saved.
The problem – from a political standpoint – is that Covid-19 kills older people, who vote, whereas school closures kill young people, who are intentionally disenfranchised.
And, personally, as someone with far-left political views, it’s sickening for me to see “my” political party adopt policies that are so destructive to children and disadvantaged people.
So, here’s what the scientific data can tell us so far:
We will eventually have effective vaccines for Covid-19. Probably within a year.
Covid-19 spreads even with social distancing and masks, but the spread is slower.
You have no way of knowing the risk status of people in a stranger’s bubble. (Please, follow your local mask orders!)
Schools – especially elementary schools – don’t contribute much to the spread of Covid-19.
School closures shorten children’s lives (and that’s not even accounting for their quality of life over the coming decades).
An individual case of Covid-19 is about twice as dangerous as a case of seasonal influenza (which is scary!).
Underlying immunity (from prior disease and vaccination) to Covid-19 is much lower than for seasonal influenza, so there will be many more cases.
Most people’s immunity to Covid-19 probably lasts several months, after which a person can be re-infected and spread the virus again.
So, those are some data. But data don’t tell us what to do. Only our values can do that.
We are wearing masks. At school, at work, at the grocery store. I jog with a bandanna tied loosely around my neck, politely lifting it over my face before I pass near other people.
Slowing the spread of a virus from which we have short-duration immunity is dangerous, as I’ve described at length previously, but one consequence of universal mask orders is unambiguously good – the herd immunity threshold to end the pandemic is lower in a world where people always wear masks around strangers.
We all want to get through this while causing as little harm as possible.
Covid-19 is real, and dangerous. Some of the data are complicated, but this much is not: to date, ~200,000 people have died from Covid-19.
Covid-19 is extremely easy to transmit. Because our behaviors so readily affect the health of others right now, we must decide collectively how to respond. My county has decided that we should wear masks. And so I do.
Only those with whom we are closest will see us smile in person. Family. If we’re lucky, a close group of friends.
We share the same air.
During the pandemic, those we love most are our conspirators.
Our conspirators are the select few whom we breathe (spirare) with (com).
I live in a college town. Last week, students returned.
Yesterday’s paper explains that dire punishment awaits the students who attended a Wednesday night party. In bold letters atop the front page, “IU plans to suspend students over party.”
In the decade that I’ve lived here, many parties have led to sexual assaults, racist hate speech, and violence. The offending students were rarely punished. But this party was egregious because “there were about 100 people there.”
IU officials “have seen a photo … that shows a large group of young people standing close together outside a house at night, many of them not wearing masks.”
I’ve seen the images – someone filmed a video while driving by. There they are – a group of young people, standing outside.
Science magazine recently interviewed biologist Dana Hawley about social distancing in the animal kingdom.
When spiny lobsters are sick, their urine smells different. Healthy lobsters will flee the shared den. Leaving is dangerous, since the lobsters will be exposed to predators until they find a new home, but staying would be dangerous, too – they might get sick. To survive, lobsters have to balance all the risks they face.
My favorite example of social distancing in the animal kingdom wasn’t discussed. When an ant is infected with the cordyceps fungus, it becomes a sleeper agent. Jennifer Lu writes in National Geographic that “as in zombie lore, there’s an incubation period where infected ants appear perfectly normal and go about their business undetected by the rest of the colony.”
Then the fungus spreads through the ants body, secreting mind control chemicals. Eventually, the fungus will command the infected ant to climb to a high place. A fruiting body bursts from the ant’s head and rains spores over the colony.
Infection is almost always lethal.
If an ant notices that a colony member has been infected, the healthy ant will carry the infected ant away from the colony and hurl it from a cliff.
The herd immunity threshold isn’t an inherent property of a virus – it depends upon our environment and behaviors. In prisons, we’ve seen Covid-19 spread until nearly 90% of people were infected. In parts of New York City where many essential workers live in crowded housing, Covid-19 spread until 50% of people were infected.
In a culture where everyone kissed a sacred statue in the center of town each morning, the herd immunity threshold would be higher. If people wear masks while interacting with strangers, the herd immunity threshold will be lower.
In a world that maintains a reservoir of the virus, though, someone who hasn’t yet been exposed will always be at risk.
The New York Times recently discussed some of the challenges that colleges face when trying to reopen during the epidemic.
Most schools ban … socializing outside “social pods” – the small groups of students that some colleges are assigning students to, usually based on their dorms.
Most administrators seem to believe that a rule banning sex is unrealistic, and are quietly hoping that students will use common sense and refrain from, say, having it with people outside their pod.
In 2012, The Huffington Post published a list of the “Top 10 sex tips for college freshmen.” Their fourth piece of advice (#1 and #2 were condoms, #3 was not having sex while drunk) is to avoid having sex with people who live too close to you. “Students in other dorms = fair game. Students in same dorm = proceed with caution.”
I had a big group of friends for my first two years of college. After a breakup, I lost most of those friends.
This is crummy, but it would be much worse if I’d lost my friendships with the only people whom the administrators allowed me to spend time with.
We can slow the spread of Covid-19, but slowing the spread won’t prevent deaths, not unless we can stave off infection until there is a highly effective vaccine. That might take years. We might never have a highly effective vaccine – our influenza vaccines range in efficacy from about 20% to 80%, and we have much more experience making these.
Our only way to reduce the eventual number of deaths is to shift the demographics of exposure. If we reach the herd immunity threshold without many vulnerable people being exposed, we’ll save lives.
A college would best protect vulnerable students and faculty by allowing the students who are going to socialize to host dense parties for a few weeks before mingling with others. This would allow the virus to spread and be cleared before there was a risk of transferring infections to vulnerable people.
I’d draft a waiver. Are you planning to socialize this semester? If so, come do it now! By doing so, you will increase your risk of contracting Covid-19. This is a serious disease – it’s possible for young, healthy people to die from it. But, look, if you’re gonna socialize eventually, please just get it over with so that you don’t endanger other people.
With this plan, some young people might die of Covid-19. But some young people will die of Covid-19 even if everyone practices social distancing – slowing the spread of infections doesn’t save lives, it delays deaths. And fewer young people would die of Covid-19 than die of influenza each year.
When confronting cordyceps, which is almost always fatal, ants throw sick colony members off cliffs.
When ants confront less lethal fungal infections, they protect the colony by shifting the demographics of exposure and by ramping up to the herd immunity threshold as quickly as possible.
Malagocka et al. discuss demographics in their review article, “Social immunity behavior among ants infected by specialist and generalist fungi.”
Outside-nest foragers, who have the highest risks of acquiring pathogens from the environment, have limited access to the brood area with the most valuable groups, and are recruited from older individuals, who are less valuable from the colony survival perspective.
Konrad et al. discuss intentional exposure in their research article, “Social transfer of pathogenic fungus promotes active immunization in ant colonies.”
When worker ants encounter an infected colony member, they intentionally inoculate themselves. “Social immunization leads to faster elimination of the disease and lower death rates.”
It feels disquieting for me to defend the behavior of frat guys. Personally, I’d like to see the whole fraternity system abolished. And in March, when we knew less about Covid-19, I was appalled that people went out partying over spring break. But I was wrong. Perhaps inadvertently, those young people were behaving in the way that would save most lives.
the nurse called back and told us to use bleach on anything we touch, she said wash everything in hot water, insisted we won’t treat you if you’re asymptomatic, we won’t, and made us an appointment anyway. so we waited and waited with the dog-eared magazines and recall posters
It’s horrible to face the end. It’s almost worse to know that the things you fear are harmless to others. All the asymptomatic cases are like a slap in the face to those whose friends and family have died.
Braun et al. recently published a study in Nature showing that a large number of people who’ve never encountered Covid-19 may already have significant immunity. Parts of the Covid-19 virus are similar to the viruses that cause common colds, and exposure to those viruses might provide the immunity that lets people recover without ever feeling sick.
I believe we should be doing more to protect young people. Gun control, ending farm subsidies, fighting climate change. Enacting privacy laws to reign in the surveillance capitalists. Breaking up monopolies. Providing good careers despite automation. Making sure that everyone has clean air to breathe and clean water to drink. Getting nutritious food into our nation’s many food deserts. Providing equitable access to health care.
But, punishing young people for socializing?
We’re not making them safer. And we’re not making ourselves safer, either.
Seriously, I know we humans are selfish, but we have to be able to handle an epidemic better than ants.
