Hello /sci/, there's a hypothesis by leading German virologist Christian Drosten which could explain the apparent disparity in Covid-19 case severities and fatalities among young, healthy patients. Here's the gist of it:
If you get the virus from surface contacts, it will first multiply in your throat which gives healthy people time to produce antibodies by the time the virus reaches the vital organs such as heart and especially lungs.
If some Boomer coofs the virus directly into your face and you inhale it into your lungs, there's barely any response time and even a young healthy person can succumb to it.

Seems reasonable to me. Is this a novel hypothesis or have virologists already accounted for it - I imagine it would be difficult to test.
