Is it possible to get more protection against coronavirus by wearing two masks?
Experts believe that this is not always the case, but in some cases two masks are useful. The American Center for Disease Control and Prevention (CDC) recommends a cloth mask that has two layers and can cover the mouth and nose. The agency recommends that the masks be made in such a way that there are no cracks on either side of the nose.
According to Dr. David, an epidemiologist at Boston University, wearing a mask is often enough if it is not loose. “It’s better to start with a good mask.”
But some people want more protection where they stay longer in enclosed spaces, such as during air travel. In this case, Dr Monica Gandhi, an epidemiologist at the University of California, says one solution is to wear a cloth mask as well as a surgical mask. He says that in such a case, protection like N95 mask can be obtained. He says the solution is useful in situations where the epidemic is spreading rapidly and people have to stay in confined spaces for longer.
He says the second solution is to wear a two-layer cloth mask that contains filter material.
They say that for everyday use if a cloth mask is made up of two layers and the cloth is made of more fine fabric, it can be difficult for the particles that carry the virus to fall out of it.
