My roommates (likely) had it while I quarantined for a few months in a different location early on in this pandemic.

Their experience was extreme fatigue (totally exhausted going up two flights of stairs), moderate cough, and a very high fever they’re both healthy early-30s.

Everything I have read seems to indicate the severity is heavily tied to your viral load. If you get a lot of the virus your body has to fight harder than a small amount. This is part if the reason masks and avoiding indoor spaces seems to help.

Edit: They both recovered but one roommate says it took about eight weeks to feel “normal” again. No apparent long term damage, but we shall see.
