> How are they able to determine that 'long covid' is a thing? Long COVID "a thing" because studies have found that it's common for at least one disease symptom to persist well beyond the initial phase of the illness. > In this systematic review of 45 studies including 9751 participants with COVID-19, the median proportion of individuals who experienced at least 1 persistent symptom was 73% https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8155823/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8155823/

Here’s a larger study of ~30,000. https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2785832 https://jamanetwork.com/journals/jamainternalmedicine/fullar... > Findings suggest that persistent physical symptoms after COVID-19 infection should not be automatically ascribed to SARS-CoV-2; a complete medical evaluation may be needed to prevent erroneously attributing symptoms to the virus. It seems to me that we basically don’t know anything about Long COVID, up to and including its potential existence.

This study does not address my comment. Symptoms included in your quoted stat include "any symptom", "generalized discomfort", depression, anxiety, headache, and a bunch of other that aren't even symptoms of covid. Anxiety is evidence of long covid symptoms? This is absurd, why do you bother to go find some terrible study to quote without having read it?

  Sorry you don’t feel like this meta analysis addresses your comment. To answer your follow-up question about anxiety, severe Covid-19 presentations commonly exhibit neuroinflamation that may damage the nervous system and may manifest as a variety of psychiatric disorders, including anxiety. This is likely why the authors of the original meta included these neuropsychiatric symptoms in their analysis.
