If that's what they mean by "growing evidence" I'm not very impressed.vnatale wrote: ↑Mon Jul 20, 2020 9:54 am Researchers say the benefits of widespread mask use were recently seen in a Missouri hair salon, where two stylists directly served 139 clients in May before testing positive for Covid-19. According to a recent report published by the CDC, both wore either a double-layered cotton or surgical mask, and nearly all clients who were interviewed reported wearing masks the entire time.
After contact tracing and two weeks of follow-up, no Covid-19 symptoms were identified among the 139 clients or their secondary contacts, the report found. Of the 67 who were willing to be tested, all were negative for Covid-19.
And what's this with all the testing about how far a cough will travel? If you have a cough shouldn't you be staying at home? In my own experience I don't recall anyone ever coughing when I went to the store. If they did I'm sure they would get lots of dirty looks. And is there a study that shows what percentage of people would venture out with a cough thinking that wearing a mask will prevent them from spreading the disease?
