So you stick to the party line despite vast evidence to the contrary?

My SIL has never been the same (her words) since she got it--note that she does *not* live in the US where it's a political issue.

The fundamental problem is that "Long Covid" is one of these "diagnoses" that are just a description of a widely varying set of symptoms and do not identify the actual problem. For a similar example consider AIDS. There we could at least identify the vector but until we discovered HIV we weren't very effective at dealing with it. This time around we know the underlying pathogen but not the mechanism of action.

SARS had many of the same lasting effects and was never thought to be hypochondria.

With measurement of known biomarkers corresponding to well-established symptoms from decently well understood physiological damage which stems from the ability of the virus to do this and that. For instance.

How do you get out of bed in the morning? Do you fall out our do you have someone to assist you?

When you have millions of formerly healthy, active people reporting the same thing, unable to get out of bed for more than a few hours a day, unable to do complicated tasks or do the things they enjoyed, something is clearly going on.

I had Chronic Fatigue Syndrome after getting Epstein-Barr virus as a teen. I was told by many doctors that it was not a real illness and it was all in my head. I tried to make myself believe that, and eventually convinced myself that I was indeed crazy. It took about a decade to recover enough that I can live life, but I still get exhausted easily. And during that time CFS became more widely accepted as a real illness.

Now doctors are saying there is a lot of similarity between CFS and Long COVID

The same way any other illness is, I guess

How is ignorance distinguished from stupidity??
