Long Covid makes the pandemic even scarier

Unless you learned Latin and Greek or went to medical school, words such as sequelae, encephalopathy or anosmia probably mean nothing to you. That may be about to change, at least if you try to keep up with the literature about Covid-19. And if youre like me, the more you learn, the more you’ll worry.

Sequelaeare the after-effects of a disease. Encephalopathyis sickness of the brain. But brain fog is just one sequela, or potential long-term condition, of Covid-19 being observed.

Others include damage to the heart, lungs or nervous system, as well as general aching and fatigue. The possible consequences also include a lasting loss of smell (anosmia) or taste (ageusia), and more.

We are not even a year into studying SARS-CoV-2, and yet we keep bumping into surprises. To me, though, this one is the scariest so far: This coronavirus unlike its cousins, the common colds, or most seasonal flu’s apparently likes to linger.

How long these symptoms can stay in our systems remains to be seen. One German study showed that about two in three patients had heart inflammation 71 days after officially recovering from Covid-19. Other researchers found many people with damaged lungs three months after getting well. And this pandemic is less than a year old.

What we want to know is how all those people will fare in five years, or 20. Will they breathe, run, think and taste wine as they used to? But well have to wait for those studies. What does this uncertainty mean for us in 2020?

One thing it means is that we cant simply focus on mortality when assessing Covid-19s risk. For most of this year, those of us who are youngish and free of preexisting conditions respected but didnt dread SARS-CoV-2. After all, if my children or I get it, we’ll probably survive. And then we will be rid of it and immune for a while. Right?

Long Covid challenges that logic. Should I therefore worry more now? What isthe right way to think about all this?

I’ve long been fascinated by the proven inability of Homo Sapiens to assess risks rationally. The likes of Daniel Kahneman and Amos Tversky have documented, sometimes hilariously, how we keep falling into mental traps in our everyday lives. We regularly panic over things that are banal and ignore risks that are grave.

Personally, Ive always been amazed that many people are afraid of cellphone radiation even as theyre merrily fiddling with their iPhones while driving. The risk of the former is negligible (because the radiation isnt ionizing). The risk of the latter is huge, because our brains cant cognitively handle the distraction while also focusing on the road.

The risks

And yet the two risks present themselves differently. The radiation is invisible and does something to us inside, with effects that might become evident only over time. We feel we have no control. The effects of distracted driving are visible and immediate: Either we cause a crash or we dont. And we feel we have control because, after all, we didnt crash yesterday or the day before.

Psychologically, short and long Covid are analogous. When I thought the disease was short and binary you had it or you no longer had it it seemed like distracted driving. I put on a mask and washed my hands in the same way as I put on my seat belt, and kept the illusion of control.

The prospect of long Covid feels more like the risk of radiation or of lead in our paint chips or all the other toxins out there. It can get into us and then stay, stealthily causing unknowable harm. SubjectivelyI feel worsebecause I no longer have the illusion of control. And unlike non-ionizing cellphone radiation, long Covid actually may be serious.

I first wrote about Covid-19 in January, when we didnt even have a name for it. Since then Ive repeatedly pondered why were so at each others throats about how to deal with this pandemic lockdowns or not, masks on or off, schools open or closed, and so forth.

Its because we just dont know how to weigh the relevant risks.The risk that I die against the risk that I give it to you and you die. The risk that by doing too much to stop the virus we plunge too many into poverty 150 million, according to the World Bank who may then suffer and die from something else. The risk that by trying to save the lives of some we condemn others to depression that makes life unlivable.

The realization that Covid-19 can be a chronic disease makes all these decisions even harder because it adds another risk conundrum. We now have to weigh the dangers not only of lives ended but also of lives permanently limited. I have no easy answers. But I`m more worried about SARS-CoV-2 than I was before.
