What is the last recommendation about the type of mask to use?

It depends on your situation, but health authorities say that you should cover your nose and mouth, and adjust so that there are no gaps on the sides of your face.

The Centers for Disease Control and Prevention (CDC) also recommends opting for face masks with two or more layers and with a wire that fits over the nose to prevent air from escaping over the top. . They suggest holding it up to the light to verify that it blocks your path, which means the fabric is likely to leak more particles.

If you want additional protection, experts suggest using two masks or pairing them with an adapter to ensure there are no gaps.

Finding a chinstrap that is comfortable is also important to ensure that it is actually worn, said Laura Kwong, an associate professor of environmental health sciences at the University of California, Berkeley.

If availability is available, you can opt for disposable N95 masks for personal use, the CDC noted in an update to its recommendations. This model is considered the most effective in blocking virus particles. The agency previously said they should be reserved for health workers, but the supply has since increased.

Alternatives such as transparent or fabric masks with plastic panels on the front are recommended for people with hearing problems. Health authorities say that transparent medical masks should be prioritized for health personnel and for patients who need them.
