Long Covid: A Parallel Pandemic

Covid-19 is a vascular disease. Turns out several organs (not just lungs) have a lot of vascular area.

Similar to, say, an ABI but more so, there's no reason to think that cases would present identically. Complex systems-of-systems in homeostasis can be expected to have breakdown behaviour that clusters around some targets with a very very long tail of other less common features.

Anyone know of any good population based studies that quantify the real amount of people with long COVID-19?
