There aren’t nearly enough masks to go around for the general population so it would be reckless to recommend people in the USA wear (commercial quality) them right now due to the need for all available supplies to go to healthcare workers.
> Hand washing (1.447, 1.274–1.644) and gargling (1.319, 1.183–1.471), however, were not associated with protection. In the natural setting, hand washing and gargling showed a negative association, which may have been due to inappropriate infection control measures or aggregating infected and non-infected children to conduct those measures.
So hand washing isn't effective and masks are? That's the opposite of what we're being told for a different disease. Are you going to say we shouldn't wash our hands?
