I was walking my eldest child toward our local elementary school when my phone rang.
We reached the door, shared a hug, and said goodbye. After I left, I called back – it was a friend of mine from college who now runs a cancer research laboratory and is an assistant professor at a medical school.
“Hey,” I said, “I was just dropping my kid off at school.”
“Whoa,” he said, “that’s brave.”
I was shocked by his remark. For most people under retirement age, a case of Covid-19 is less dangerous than a case of seasonal influenza.
“I’ve never heard of anybody needing a double lung transplant after a case of the flu,” my friend said.
But our ignorance doesn’t constitute safety. During this past flu season, several young, healthy people contracted such severe cases of influenza that they required double lung transplants. Here’s an article about a healthy 30-year-old Wyoming man nearly killed by influenza from December 2019, and another about a healthy 20-year-old Ohio woman from January 2020. And this was a rather mild flu season!
“One of the doctors told me that she’s the poster child for why you get the flu shot because she didn’t get her flu shot,” said [the 20-year-old’s mother].
These stories were reported in local newspapers. Stories like this don’t make national news because we, as a people, think that it’s normal for 40,000 to 80,000 people to die of influenza every year. Every three to five years, we lose as many people as have died from Covid-19. And that’s with vaccination, with pre-existing immunity, with antivirals like Tamiflu.
Again, when I compare Covid-19 to influenza, I’m not trying to minimize the danger of Covid-19. It is dangerous. For elderly people, and for people with underlying health issues, Covid-19 is very dangerous. And, sure, all our available data suggest that Covid-19 is less dangerous than seasonal influenza for people under retirement age, but, guess what? That’s still pretty awful!
You should get a yearly flu shot!
A flu shot might save your life. And your flu shot will help save the lives of your at-risk friends and neighbors.
For a while, I was worried because some of my remarks about Covid-19 sounded superficially similar to things said by the U.S. Republican party. Fox News – a virulent propaganda outlet – was publicizing the work of David Katz – a liberal medical doctor who volunteered in a Brooklyn E.R. during the Covid-19 epidemic and teaches at Yale’s school of public health.
The “problem” is that Katz disagrees with the narrative generally forwarded by the popular press. His reasoning, like mine, is based the relevant research data – he concludes that low-risk people should return to their regular lives.
You can see a nifty chart with his recommendations here. This is the sort of thing we’d be doing if we, as a people, wanted to “follow the science.”
And also, I’m no longer worried that people might mistake me for a right-wing ideologue. Because our president has once again staked claim to a ludicrous set of beliefs.
Here’s a reasonable set of beliefs: we are weeks away from a safe, effective Covid-19 vaccine, so we should do everything we can to slow transmission and get the number of cases as low as possible!
Here’s another reasonable set of beliefs: Covid-19 is highly infectious, and we won’t have a vaccine for a long time. Most people will already be infected at least once before there’s a vaccine, so we should focus on protecting high-risk people while low-risk people return to their regular lives.
If you believe either of those sets of things, then you’re being totally reasonable! If you feel confident that we’ll have a vaccine soon, then, yes, delaying infections is the best strategy! I agree! And if you think that a vaccine will take a while, then, yes, we should end the shutdown! I agree!
There’s no right answer here – it comes down to our predictions about the future.
But there are definitely wrong answers. For instance, our current president claims that a vaccine is weeks away, and that we should return to our regular lives right now.
That’s nonsense. If we could get vaccinated before the election, then it’d make sense to close schools. To wait this out.
If a year or more will pass before people are vaccinated, then our efforts to delay the spread of infection will cause more harm than good. Not only will we be causing harm with the shutdown itself, but we’ll be increasing the death toll from Covid-19.
On October 14th, the New York Times again ran a headline saying “Yes, you can be reinfected with the coronavirus. But it’s extremely unlikely.”
This is incorrect.
When I’ve discussed Covid-19 with my father – a medical doctor specializing in infectious diseases, virology professor, vaccine developer with a background in epidemiology from his masters in public health – he also has often said to me that reinfection is unlikely. I kept explaining that he was wrong until I realized that we were talking about different things.
When my father uses the word “reinfection,” he means clearing the virus, catching it again, and becoming sicker than you were the first time. That’s unlikely (although obviously possible). This sort of reinfection happens often with influenza, but that’s because influenza mutates so rapidly. Covid-19 has a much more stable genome.
When I use the word “reinfection” – and I believe that this is also true when most laypeople use the word – I mean clearing the virus, catching it again, and becoming sick enough to shed the viral particles that will make other people sick.
This sense of the word “reinfection” describes something that happens all the time with other coronaviruses, and has been documented to occur with Covid-19 as well.
The more we slow the spread of Covid-19, the more total cases there will be. In and of itself, more cases aren’t a bad thing – most people’s reinfection will be milder than their first exposure. The dangerous aspect is that a person who is reinfected will have another period of viral shedding during which they might expose a high-risk friend or neighbor.
If our goal is to reduce the strain on hospitals and reduce total mortality, we need to avoid exposing high-risk people. Obviously, we should be very careful around nursing home patients. We should provide nursing homes with the resources they need to deal with this, like extra testing, and preferably increased wages for nursing home workers to compensate them for all that extra testing.
It’s also a good idea to wear masks wherever low-risk and high-risk people mingle. The best system for grocery stores would be to hire low-risk shoppers to help deliver food to high-risk people, but, absent that system, the second-best option would be for everyone to wear masks in the grocery store.
Schools are another environment where a small number of high-risk teachers and a small number of students living with high-risk family members intermingle with a large number of low-risk classmates and colleagues.
Schools should be open – regions where schools closed have had the same rates of infection as regions where schools stayed open, and here in the U.S., teachers in districts with remote learning have had the same rates of infection as districts with in-person learning.
Education is essential, and most people in the building have very low risk.
A preponderance of data indicate that schools are safe. These data are readily accessible even for lay audiences – instead of reading research articles, you could read this lovely article in The Atlantic.
Well, I should rephrase.
We should’ve been quarantining international travelers back in December or January. At that time, a shutdown could have helped. By February, we were too late. This virus will become endemic to the human species. We screwed up.
But, given where we are now, students and teachers won’t experience much increased risk from Covid-19 if they attend in person, and schools aren’t likely to make the Covid-19 pandemic worse for the surrounding communities.
That doesn’t mean that schools are safe.
Schools aren’t safe: gun violence is a horrible problem. My spouse is a teacher – during her first year, a student brought weapons including a chainsaw and some pipe bombs to attack the school; during her fourth year, a student had amassed guns in his locker and was planning to attack the school.
Schools aren’t safe: we let kids play football, which is known to cause traumatic brain injury.
Schools aren’t safe: the high stress of grades, college admissions, and even socializing puts some kids at a devastatingly high risk for suicide. We as a nation haven’t always done a great job of prioritizing kids’ mental health.
And the world isn’t safe – as David Katz has written,
“If inclined to panic over anything, let it be climate change … Not the most wildly pessimistic assessment of the COVID pandemic places it even remotely in the same apocalyptic ballpark.”
