MASKS
One comment about masks and nonlinearities that these imbeciles are not getting.

Reducing exposure to viruses by 30% thanks to an "imperfect" mask does not mean reducing risk of contracting the disease by just 30%. By convexity, it must be more than 30%, can even be 95%.
That's for an individual. If everyone wore *VERY BAD* masks, I guess the number of deaths would drop by a yuuuge factor, maybe 90%. Why? p is probability of infection, look at 1-p^n because everyone is reducing.

For 2 pple masks act a 2-way filter, 1-p^2. Yuuge.
