From Bertorelli: “My view was always that mitigations such as masks and distancing were weak at best, but just worth doing.” Worth doing? Yes! “Weak at best”? Totally not true. As we all know, the devil is in the details. Wearing a properly fitted N-95 mask is incredibly effective. That is why doctors and nurses wear them when caring for active tuberculosis patient. The problem comes with the square (usually blue) surgical masks whose inhalation filtration is negligible, and they don’t fit closely enough (especially around the nose) to be protective. They were designed to keep moisture ladened exhaled bacteria from infecting the surgical site. And we also know that distance works. The more space between you and an infected individual, combined with masking, is very effectiver
