Thanks for the well wishes.
Yes, post viral syndrome has always existed in a small minority of people with flu and glandular fever et al. But proportionally speaking long covid is a much, much bigger problem. Collectively, there are a quarter of a million people in the UK living with ME/CFS - there are already more than that with long covid, after only 2.5 years of its existence. The workforce has been rapidly depleted in a way that has never happened with a flu outbreak.
Plus, like a pp said, the risks are different. With data coming out about increased stroke and cardiac risks even after recovery, the long term consequences of covid infections seems to be far, far greater in the general population than something like the flu ever was, even setting long covid aside (which, ya know, I'd rather we didn't.)
