>>11891221>Ok, so why should we keep wearing these face diapers?Because the "science" is conclusive that they do work. Real world scenarios show us this. The very first freaking paragraph in your link is incorrect.
"The main transmission path is long-residence-time aerosol particles (< 2.5 ?m), which are too fine to be blocked"
It's because of physics that they can block particles much finer than their pore size. You don't even have to look at the physics, just look at the studies challenging masks with particles of .1 microns. Even homemade cotton masks do a decent job.
"and the minimum-infective-dose is smaller than one aerosol particle"
We frankly don't know what that dose is for any virus, but there's clearly a threshold, and the body can prevent infection below a certain threshold, otherwise something like measles (which is extremely infectious) would have a 100% infection rate, which it doesn't. One particle may find a cell, and a thousand might not. Even if a cell or several cells are infected, there's no guarantee that it will set off a chain reaction. There's been studies in the past where attempts were made to infect people with respiratory viruses, inserted straight into the sinuses, and some subjects remained uninfected. We have antiviral factors in our mucus, and cilia that push viruses down to the stomach where they're denatured by stomach acid. The smaller the dose, the higher the likelihood those protective mechanisms will work.
His argument about humidity is somewhat correct, the only problem is it's clearly still spreading in countries with high levels of humidity whereas influenza is basically non-existent. Obviously there's some variation between viruses, with some more hardy than others.
