Who do masks protect from COVID-19: the wearer, others, or both?
See full answerWe’ve known for some time that masks help prevent people from spreading the coronavirus to others. Based on an analysis of existing information, a new study contends that masks may also protect mask wearers from becoming infected themselves.Different masks, writes the study author, block viral particles to varying degrees. If masks lead to lower “doses” of virus being inhaled, then fewer people may become infected, and those who do may have milder illness.Researchers in China experimented with hamsters to test the effect of masks. They put healthy hamsters and hamsters infected with SARS-CoV-2 (the COVID-19 coronavirus) in a cage, and separated some of the healthy and infected hamsters with a barrier made of surgical masks. Many of the “masked” healthy hamsters did not get infected, and those who did got less sick than previously healthy “maskless” hamsters.

How are N95 face masks intended to be disposable?
Like surgical masks, N95 masks are intended to be disposable. However, researchers are testing ways to disinfect and reuse them. Some N95 masks, and even some cloth masks, have valves that make them easier to breathe through. Unfortunately, these masks don’t filter the air the wearer breathes out.
Why are face masks banned in some places?
But because the valve releases unfiltered air when the wearer breathes out, this type of mask doesn’t prevent the wearer from spreading the virus. For this reason, some places have banned them. A cloth mask is intended to trap droplets that are released when the wearer talks, coughs or sneezes.
