My mother-in-law had an absolutely BRUTAL flu in early February. It was so bad my sister-in-law had to live with her for a while and take care of her. She had really, really bad fevers and an absolutely horrible dry cough that seems to have left some lasting damage even now. It took her about 3 weeks to get better. There's no evidence that it was Covid-19. But she is a nanny for a family of doctors in Boston so it's not impossible that it's it.
