[MatteasM (OP)]

Are there any theories of what exactly is happening after the Covid-19 virus enters the system and the mechanism by which it kills? I have only come across one reasonable theory on SSRN that discusses mast cell degranulation. Almost all other scientific presentations seem to be data sets of symptoms and morbidities and genetic analysis of the virus and its receptors.

Our medical establishment has nothing more than shots in the dark, hoping for a lucky hit. It seems that despite the trillions poured into setting up research superstructure, we are not even sure anymore if we should be using anti-parasite and/or antibiotic treatments to deal with a virus! Or even whether  a mask will help or not?

Where is the medical theory? Where are the old school immunologists?
