The recent study where they intentional infected a bunch of paid volunteers and tracked what happened over the next year is really concerning. All of them have lasting brain damage and none of them can tell this occurred. The Long Covid studies are struggling to find healthy controls because there are a lot of people now walking around with the metabolic and vascular problems that are found in Long Covid but appear asymptomatic. This virus is doing a lot of damage and everyone is one infection away from their life being destroyed by Long Covid.
The studying I am referring to https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(24)00421-8/fulltext
Bare in mind it's one in 400k such studies showing the damage of Covid it's no outlier it's just really dumb.
