The mask guidance is confusing as well. I get they are trying to preserve masks for medical staff. But, they also say it's mainly spread by coughing, sneezing, and resulting spray of bodily fluids. Surely even a scarf around your face would have some benefit? Yes, I get that the virus is small enough to pass through, but some deflection is better than none.
I was wondering the same. I'm by no means professional but it seems to be better than nothing, especially for people who sneeze. In China, it's pretty much contained now, and everyone wears masks on the street -- The thing is, there are 1.3 billion people, of course there are a lot of people couldn't buy or afford surgical masks, let alone N95 masks. It turns out people wear regular masks, or even they don't have any…
Sorry to nitpick, but it's N95 respirators not masks. There's be a lot of terminology confusion on this topic, and I think it's making communication significantly more difficult on this topic.
