Before any non-specialist attempts to write something on COVID-19, we should wonder: are any actual experts already writing on this, and if not, why not. Enough badly informed stuff has already been published by amateurs that before posting we should be certain we are actually being helpful. October 2022 UPDATE: I've removed the rest of this post. Turns out everyone (including me) was wrong, and we didn't understand pandemics of respiratory diseases very well.
