I get really bad throat infections with flu-like symptoms a few times a year and they're very unpleasant for a few days to a week but as with the flu young/healthy people will likely get over it. It just seems to be mostly killing the already nearly-dead with underlying health conditions anyway and they're probably the ones that need to self-isolate unless it starts killing anyone else.
Yesterday, a 48 year old woman died with no known preconditions in self quarantine.
I have read reports of deaths of formerly healthy doctors and nurses in wuhan, died of covid in their early 30's.
Don't be too sure...
