Excerpt From: We need to start thinking more critically — and speaking more cautiously — about long Covid
“Long Covid has no universal definition. It is instead often used as a catchall to describe individuals whose symptoms last more than a few weeks or months after the onset of Covid-19. That many individuals experience protracted symptoms after infection with SARS-CoV-2, however, should hardly be surprising. After all, critical illness of any cause can be devastating…
The symptoms of this condition are often, if not predominantly, non-respiratory in nature, and the people most affected seem to be relatively young, whereas those most susceptible to severe acute Covid-19 are, on average, older and sicker…
Reporting on long Covid needs to be more cautious for several reasons… First, at least some people who identify themselves as having long Covid appear never to have been infected with the SARS-CoV-2 virus… a survey organized by a group of self-identified long Covid patients that recruited participants from online support groups reported in late December 2020 that around two-thirds of those surveyed who had undergone blood testing reported negative results…
The symptoms reported as consistent with long Covid are associated with many conditions. Gastrointestinal symptoms, confusion and forgetfulness (“brain fog”), severe fatigue, hair loss, and headaches are surprisingly common, even in the general population… Add to that the fact that the past year has produced skyrocketing levels of social anguish and mental emotional distress… there’s no question that mental suffering can produce physical suffering…
But make no mistake: the suffering described by long Covid patients is debilitating and real. There will be, as is often the case, lack of clarity about the distinct cause of suffering in each individual; there may often be multiple causes, stretching from the virologic to the psychosocial.”

Excerpt from What is Long Covid?
I don’t think it’s any different from post-viral syndrome, a condition that affects some people after a viral infection but that usually clears up within a few months. I’ve been generally sceptical of claims of long covid as some distinct entity for a couple of reasons.
First, it’s generally impossible to separate out cause and effect from anecdote and observational data. If you have a respiratory infection and then you continue to feel tired afterwards, was it the respiratory infection that caused it or something else?
For those who have been seriously sick with covid and required intensive care, PTSD is also something that could easily be misinterpreted as long covid (PTSD is actually quite common after intensive care, affecting one in ten patients). Apart from that, some studies have found that almost 60% of people treated in intensive care (for any condition, not covid specifically) still have cognitive impairments twelve months after being discharged.
Second, covid is not some magical entity, it’s a coronavirus, and it behaves like other coronaviruses, and other respiratory viruses more generally.
Maybe it will turn out that long covid is a real entity after all (distinct from post-viral syndrome, PTSD, anxiety disorder, and so on) when better research is done down the line, but we can’t just assume it based on anecdote, fear-mongering, groupthink, and low quality science. That doesn’t benefit anyone, least of all people with other underlying health issues that are not properly investigated because it’s so easy to just blame everything on covid.
