Coronavirus/COVID-19: Face masks actually CAN help. Also beware the threats from restroom hand dryers, poop & toilet flushing

Note: proper-frequent hand-washing and other public health warnings should be followed, but there exist other significant considerations that can add to those. Several of those, are below, along with links to peer-reviewed scientific papers (and a couple of well-sourced articles from the media and government sources)

Like most people, you you you touch your face a lot. From 16 to 23 times per hour.

That means that the overwhelming proliferation of public health warnings that wearing face masks will n0t protect you from contracting COVID-19 are wrong/incomplete.

However, masks are a physical barrier to that contact, and can be a psychological reminder to avoid eye touching. Wearing glasses is yet another reminder/barrier.

Public restrooms are not your friend

Modern flush toilets and hot air hand dryers can spread bacteria — including e. coli and other fecal germs and viruses. The flushing turns part of the toilet contents into an aerosol which can be breathed in, and also recirculated by the hand dryers.

This would not be as much a problem if a toilet lid were closed before flushing. But almost all public toilets lack lids,
