Re: the mutations. This may be why there have been reports of various types of damaged human parts and systems.

From The Lancet

Quote : Not only capable of causing pneumonia, COVID-19 may also cause damage to other organs such as the heart, the liver, and the kidneys, as well as to organ systems such as the blood and the immune system.
Patients eventually die of multiple organ failure, shock, acute respiratory distress syndrome, heart failure, arrhythmias, and renal failure.
We should therefore pay attention to potential multi-organ injuries and the protection and prevention thereof in the treatment of COVID-19.

This is why a one shoe fits all approach to treatment of infection symptoms does not work. As above, stay in, wait for a safe and effective vaccine. Keep in mind the more people (currently 430k+) that get infected the more opportunity for mutations. The tide is turning, lets not let it get out of hand by going back to "usual" activities, The Doctors will ultimately figure it out, hopefully before it mutated to where they need to start over. It's like catching a rat, got to get it cornered.
