How are the various styles of masks working?
Surgical Mask
Often known as a medical mask, a surgical mask is a loose-fitting disposable mask that covers the nose and mouth of the wearer from contact with droplets, splashes, and sprays that may contain germs. The surgical mask often removes huge objects out of the air. Surgical masks can protect others by reducing the exposure of the mask wearer to saliva and respiratory secretions.

The U.S. at this time. Food and Drug Administration has not licensed any form of surgical mask explicitly designed to protect against coronavirus, although these masks provide some protection when N95 masks are not available.

Clothe masks
A fabric mask is designed to capture droplets that are emitted while the wearer speaks, coughs, or sneezes. Asking everybody to wear cloth masks will help minimize the transmission of the virus to those who have COVID-19 but don’t know it.

Cloth face coverings are more likely to minimize the transmission of the COVID-19 virus as individuals are commonly used in public settings. And countries that needed face masks, testing, quarantine, and social distance early in the pandemic have effectively delayed the spread of the virus.

While surgical and N95 masks can be in short supply and should be reserved for health care providers, face cloth and masks are easy to find or make and can be cleaned and reused.

Masks may be made from traditional materials, such as sheets of closely woven cotton. The directions are easy to find on-line. Cloth masks should contain several layers of fabric. The CDC website also provides instructions for no-saw masks made from bandannas and t-shirts.
