I think a lot of the insistence on the “long covid “ terminology is just wanting acceptance that covid-19 can cause these post-viral symptoms, which a lot people still don’t accept, as demonstrated in this thread with people saying it’s just the stress of lockdown.

The medical community seems to take the problem(s) seriously, but has very little idea how to treat it. Hopefully the high profile of the problem will lead to increased research in this area over the next few years.
