So it seems they don’t actually know why 20% of the cases go south. All they know is who’s at risk of being in that 20% 🤔

Well, this video gives an explainer... This is the most informative video I've yet seen.
2 ways it seems: either from requiring ventilation & there being none, or by exhausting your immune system so much it's prone to bacterial infections.

My sense from other sources was that the main proximate cause is simply the viral infection becoming well established in the lower lungs, rather than just the upper respiratory tract.

I recall reading there’s a suspicion that the virus can invade nervous system / cross blood/brain barrier and there may be a higher chance of this happening if it happens to arrive intranasally

There's also no clear number to tell us what portion of that 20% will die once hospitals are truly overwhelmed and they cannot receive care. As the wave crests, death rates could end up being higher than we've been told.

Studying this virus started 3 months ago. But there's more. 4 different corona-type viruses are in the wild, they cause about 15% of common colds (all mild cases). But there is more. Of the other 200 viruses that cause the common cold, 30% were never studied.
