Scientists warn people to throw away surgical masks consisting of single layer

As the increase in Omicron cases continues at a record level around the world, scientists have urged people to throw away their surgical masks consisting of a cloth and a single layer. They comment that such masks for protection from Omicron which can also infect vaccinated people, do not work.

Actually, single-layer cloth masks which many prefer for convenience and style, are able to block larger droplets carrying the coronavirus. However, according to infectious disease experts, they are not so effective at blocking smaller aerosols or particles carrying the coronavirus.

On the other hand, most recent guide manual of the U.S. Centers for Disease Control and Prevention (CDC) have advised people to wear multi-layered and tightly woven fabric ones masks to fit the face properly and with adjustable wire for nose The manual says that it is recommended to wear a disposable mask under a cloth mask, while N95 masks should be left to health workers.
