Wear a Face Mask Or Not Wear One? After reading comments and answering questions regarding face mask here is my opinion. There are several possible routes to infection. An infected person can cough, sneeze or breathe while within about two metres of another person, and the virus lands in the other person's eyes, nose or mouth (1). Another route is when an infected person coughs or sneezes onto their hand or onto a surface. The uninfected person then shakes the hand (2a) or touches the surface (2b), and transfers the virus to their own eye, nose or mouth. It is possible that an infected person can also cough or sneeze to create an airborne spread (3) beyond the close contact range – but it is controversial whether this last route is a major means of transmission. We don't know how much transmission occurs by each of these routes for COVID-19. It's also unclear how much protection a mask would offer in each case. Current best evidence To resolve this question, we analysed 14 randomised trials of mask wearing and infection for influenza-like illnesses. (There are no randomised trials involving COVID-19 itself, so the best we can do is look at similar diseases.) When we combined the results of these trials that studied the effect of masks versus no masks in health-care workers and the general population, they did not show that wearing masks leads to any substantial reduction of influenza-like illness. However, the studies were too small to rule out a minor effect for masks. #workfromhome #coronavirus #healthcare #deliverydriver #jobsearch #ridesharedriver #hiringevents #foodservices
