I was reading studies that it is the aerosol parts of viruses that get sucked way deep in the lung that makes it so bad - which is what we see with the Wuhan virus.
Other reports though might have shown that the aerosol viruses don't last that long - although they admitted that the way they detected them (on a paper filter) might have “killed” them - the paper sucks the moisture out of the cell and they aren't viable anymore.
It’s all new to me. I never thought the surgical masks were going to do much, honestly.
Oh, another news item that this explains, the “aerosolized” virus upon flushing toilets one doctor/specialist was describing.
Problem is when you breath out the moisture in your breath makes the mask damp.
UPDATE: China’s National Health Commission reports 441 new cases of coronavirus and 7 new deaths, adding to the 2,147 cases and 81 new deaths reported 2 hours ago
