      Problem is, by its nature this research is pretty exploratory. Most studies enroll people who are engaged and interested, and thus the population is very selected

      For example, one of the best sources of information is the COVID Symptom Study, which uses an app to log details. By their very nature, apps exclude some people from using them https://covid.joinzoe.com/about

      Some of my research shows this for chronic disease - lots of people stop using apps even if they are beneficial, and this pattern is non-random https://www.jmir.org/2020/9/e20283/

      What we'd need to really understand the prevalence of #LongCovid in populations is to enroll a large group of people - including asymptomatic cases and people who don't have COVID - and follow them over time to see what happens

      We'd also need to try and get data from pretty much everyone at every time point, because it's likely that those who drop out are different to those who don't in ways that may be all but impossible to measure

      Unfortunately, that's really hard to do, so we are left to interpret the observational data that gives us, at best, a biased view of the situation

      Whenever you see a proportion being proposed (i.e. 1 in 20 people have Long COVID) it's important to understand the denominator Is it everyone? Only those in one study? Who did that study enroll?

      Important note - it's possible I've missed a large prospective study that does answer this question, I've tried to look but please do let me know if one has been published

      Important note #2 - this bias could easily bias the results IN BOTH DIRECTIONS, meaning that there could be less or far more #LongCovid than reported. There are reasonable arguments both ways!

      What’s the reasonable argument for more long Covid? That’s highly unlikely and I think you probably know that....

      The most disadvantaged people are the most likely to not engage with the surveys that have been done so far, and also the most likely to experience long-lasting symptoms. If they are truly underrepresented, the proportion could easily be higher

          While this is true I seriously doubt this effect outweighs everything mentioned above. Maybe it does but I think it’s highly unlikely. Furthermore many are arguing that even mild cases can lead to long Covid in which case those would be reflected in the surveys mentioned above.

          I am a cardiologist and it infuriates me that people with no medical degrees get on this app and postulate that we will have a whole bunch of people dropping dead from heart failure in the years to come. We do see cardiomyopathy often but this is also WAY more common with viruses

          Than people realize. We have followed up on patients with this and it almost universally resolved itself within two months (vast majority of time sooner) with no sign of anything abnormal in follow up imaging.

          This is a problem with research design generally: those who are housebound/bed bound, need to stop start surveys, have symptoms that interfere with communication/transport/screen use etc? Massive attrition & being put off participating. @JadeBarclay has great insights on this
