JackFlorey said:If that were true, once one person got a virus in a hospital everyone would have it. Yet, 99% of the time, they do not get it. Why?neptronix said:However these particles will still be diffusing through the air. None of these masks filter them. Poor fitment makes this even worse. A common HVAC system will have them circulating throughout a building. A large number of people hanging out in a building will result in a lot of transmission. This is a huge problem in hospitals actually.
Because, as always, you're wrong, one in the hospital will not give it to everyone for reasons that are well known.
. . . .therefore, the infectious dose may be hundreds of particles, Dr. Rasmussen said.
Generally, people who harbor high levels of pathogens — whether from influenza, H.I.V. or SARS — tend to have more severe symptoms and are more likely to pass on the pathogens to others.
But in the case of the new coronavirus, people who have no symptoms seem to have viral loads — that is, the amount of virus in their bodies — just as high as those who are seriously ill, according to some studies.
And coronavirus patients are most infectious two to three days before symptoms begin, less so after the illness really hits.
Some people are generous transmitters of the coronavirus; others are stingy. So-called super-spreaders seem to be particularly gifted in transmitting it, although it’s unclear whether that’s because of their biology or their behavior.

Adam Tooze said:As we have learned during the COVID-19 pandemic, one of the main functions of a face mask is to remind oneself of invisible dangers and to signal to others that one is taking those risks seriously. In the United States they have become something like an article of faith, a way of indicating publicly that one belongs to those who take “the science” seriously.
