Lung CT of a 40-year-old patient, 6 weeks after Covid-19 infection, subjectively he feels well, with exertion (5 squats) a drop in oxygen saturation as a sign of a lung shunt. Massive consolidations and infiltrates on both sides.

Then you are fortunate to have 60 face masks that you can use over a 2-month period. Lucky you. All the stores I have seen are flat out of disposable face masks and none are to be found. I was talking about all the people I see re-using face masks for days on end. I don’t know how you managed to stockpile 60 face masks or more going into this crisis that came at us out of the blue, but lucky you.
You are intelligent enough to use enough in a rotation that any potential viruses would be dead by the time you go back to each mask. That is perfectly fine. Just remember that by the 5th or 10th use, a re-used N95 mask is starting to lose its shape and the straps are starting to stretch out so the critical fit you need to maintain gets more and more difficult with each use, until it doesn’t fit well enough to filter out that 95% of particles designed to do so. For myself, I find it hard to get that “right” fit on my face with a brand new perfect mask. I have trouble the most with the nose bridge, and I usually have to adjust it a few times to get that good fit all around. With one used 10 times, that fit is just not going to be available at all.
I don’t use a mask at all out and around, so I am not claiming people using masks poorly are going to be dropping like flies. What I am saying is, IF people were genuinely being exposed frequently to the Covid 19 virus, the vast majority would become infected due to generally incorrect use, fit, and storage of masks and other hygiene practices.
People keeping good social distancing, washing their hands frequently, and not touching their hands to their faces after touching strange surfaces, are not going to expose themselves to the virus, so they don’t need a mask at all. So all these people mis-using masks are good to go. They are not being exposed at all and it is a waste of using masks 99.9% of time.
If I have to wear something on my head to mock them then I'm going as Mr. Apocalypse in 9/8
