On this account, I'll not talk about politics, not even an ounce related to COVID policies. Talking about politics is defensive. Now we're going offensive.

In general, I think people know about the hazard of COVID infections, but most don't understand the difference between airborne pathogens (i.e. receptors in the nose/mouth/airway) and others with different transmission routes. The key is dosage, which enhances survival rate.

In this regard, we depend more on innate immunity to airborne pathogens than others, since high dosage -> high replication -> high chance for viral reservoirs. We just can't wait 10+ days for adaptive T/B cells to join in.

So consequently we need to reduce burden on innate immunity, by eliminating as much viral/bacterial load in the air as possible, in efficient ways.
