Maybe I'm way off base.  My impression is that if you test positive for Covid they send you home and do nothing.  Then if you get really sick you can try to get a bed in the hospital.

Why don't they give you one of the 3 medications that they use to treat the really sick people before they become the really sick people?  I've read of cases that people weren't terribly sick but died from the virus. 

It seems that there is no definite and sure way to predict the outcome of having this disease.
