WHO is not giving out the best advice these days. That Fauci statement was from 3/8 before shit really hit the fan in the US and he was trying to preserve supply for healthcare workers. Fauci is wearing a mask now in public. Cloth face masks are a good idea in indoor public spaces... it is about reducing the load of virus I would expel into a closed space if I am infected and don't know it yet. Also, it reduces the distance particles travel from my mouth when breathing or talking. These two things together reduce the risk for those around me in enclosed spaces. It also provides some moderate reduction in aerosol I inhale. This has been studied and well documented. We know now that transmission through common surface contact is minimal... not zero, but very low compared to aerosol transmission. The risk of touching your face more is not significant enough to offset the benefit of wearing a mask. I probably touch my face more without a mask on. That being said, it is important that your mask be comfortable so that the need to adjust it is minimal. I wear a mask at work and wash my hands and mask with warm very dish-soapy water for 20-30 seconds when I get home. I also wash my hands regularly during the day. Soap is very effective at inactivating most all virus; commonly wrecking their surface proteins (that they need intact to get into cells) or even destroying the capsid shell. FWIW: We are also running ozone generators at night where I work in the high traffic areas to provide a 2-3 log reduction of active surface virus (should any exist). I don't recommend doing this unless you really know what you are doing... exposure to high concentrations of ozone is really bad for you (read, can kill you if exposure is bad enough).

  Yes, I agree, when there was a big shortage of tests and ppe they said reserve ppe for first responders (docs, emt, hosp workers) and tests for really sick. Now we have more information and more medical masks.
