The U.S. Centers for Disease Control and Prevention (CDC) on Friday, January 14, updated information about wearing masks for the American public, including clarifying that certain types of masks and respirators provide more protection against coronavirus than others. The CDC information on wearing masks was last updated in October last year.

"Masks are an essential public health tool for preventing the spread of COVID-19, and it's important to remember that any mask is better than no mask," the CDC said in a statement quoted by CNN.

The updated guidelines advise Americans to wear N95 and KN95 respirators. In addition, it is noted that disposable masks provide the least protection against the omicron variant of the coronavirus. Recently, more Americans are opting for masks with a higher level of protection against the backdrop of a sharp increase in the number of cases of infection with a deadly infection, specifies Reuters.

Recall that the United States leads the world in the number of deaths from COVID-19 - about 850 thousand cases. The situation is compounded by the refusal of some Americans to vaccinate. President Joe Biden said on Thursday that the federal government plans to provide Americans with "high quality masks" for free. In addition, the White House said the government will begin shipping 500 million COVID-19 tests to Americans for free at the end of January.
