Just watching a video of john campbell were he says that, one of the "Long term" side effects of getting covid19 is supposedly Diabetes.
Its only anecdotal so far, ei. people have noticed what appears to be a uptrend in diabetes, amoung people that have had covid19 and recovered.
(this doesnt mean everyone that gets covid, gets diabetes, just the chances of you developeing it, rise afterwards, like it can trigger it)
Apparently they also saw this same trend when they did experiments with infecting mice, with covid19.
Time to invest in a drug company that makes insulin I guess.
Also pulmonary fibrosis (lunge scarring).
Which is apparently common, even if you barely have symptoms, and recover, afterwards your lunges arnt as great as they were before you got covid19.
