My wife had COVID-19 in April with a medical precondition. She was in bed for three weeks. Symptoms were completely different from flu, mostly just feeling completely exhausted and weak. She went back to work after about a month, and now her health is back 90% I would say. A few year agao I had a bad case of flu. Temperature rose again after a few days, which indicated a bacterial superinfection, which got treated with antibiotics. I was back at work after two weeks. But I have the feeling that these two weeks had changed by body. It took me about half a year to fully recover, i would say. We often discuss who was hit worse, my wife with COVID-19 or me with the flu. Probably my wife, but she had her medical precondition, so we have not come to a final conclusion.
