My grandparents got the virus, I think, they didn't get tested, but the symptoms were pretty much textbook corona ones. They're feeling okay now, my grandfather was a bit worse he had 39C fever. I'd say the biggest problem is not that you can't recover from it, but that hospitals are overwhelmed and can't give you the appropriate care if you need it. My grandparents luck was that my aunt is a nurse and took care of them at home, but if they were to go to the hospital who knows how it could have turned out?
