Epidemiological research studies into Long Covid, currently defined by prolonged symptoms after SARS-CoV-2 infection, have reported widely varying prevalence estimates. As well as rapidly evolving scientific knowledge of Long Covid, these differences are partly driven by substantial methodological heterogeneity between studies, including the outcome definition of Long Covid; duration of follow-up; study design, period and population; sampling frame; data source; and the statistical techniques employed.

Having a robust understanding of the prevalence of and risk factors for Long Covid is essential for informing treatment pathways, service provision and policy decisions.

In preparation for the public health response to future epidemics and pandemics, this review outlines key epidemiological and statistical considerations and recommendations when designing studies of emerging post-acute infection syndromes, focussing on Long Covid as a case study.

After a rough overview, this isn't all bad, but all of this was well-known by the time Covid came along, and none of that advice was actually followed. There is no reflection on the fact that all of this went completely wrong as a matter of choice, all made especially worse by focusing on UK studies, when the country has been outstandingly bad for the most part. What hubris to present an example of total failure as the basis for future success.

Of course all of this is very difficult, but nothing here is surprising or new, and it doesn't take into account how this very issue was, and remains, highly controversial, with lots of actors pushing back, successfully, against doing any of this, including some of the people in some of the studies they cite, like the Clock study, whose lead researcher was advising the UK government that LC is just a fad, nothing to worry about.

So this is all a sort of post-disaster report that does not acknowledge that a disaster took place, that most of what went wrong was entirely a choice, mostly consisting of ignoring all of this advice, all of which was well-known from day 1.

Obviously none of this will be followed the next time around. We are in year 7 of LC and it's still a total disaster for the current "case study", for which nothing is improving or even moving, so the idea of preparing for the next with advice that no one bothered following, in fact resisted, keep resisting, is just fantasy.

All of this was a choice. Yes, yes, it is all very difficult to deal with, even in ideal circumstances, even when following a carefully-crafted plan. But everything is still totally broken because all of this advice remains explicitly resisted, with the very clear intent to cover it all up. All the institutions of public health and medicine remain entirely part of the problem, refuse to change or adapt, unable to acknowledge that mistakes were made because those mistakes remain in effect.

And, of course, predictably, zero mention of ME/CFS or anything like it, which, with a focus on the UK, is especially unforgivable. It wasn't just predictable, it was predicted, people did come forward with roughly this set of recommendations, and everyone in charge, people who knew all of this, said no, absolutely not, not going to happen.

A cover up in plain sight.
