The U.S. Centers for Disease Control and Prevention (CDC) has updated its mask guidance on Friday, advising more Americans to wear masks such as N95 or KN95 masks, a type of respirators largely used by health care workers.

The federal health agency removed concerns it previously addressed that those kinds of masks are in short supply and should only be used by those in the medical sector.

In the updated guidance, the CDC underscored that properly fitted N95 and KN95 masks offer the most protection against COVID-19, saying that the shortages are no longer a concern.

White House COVID-19 response coordinator Jeff Zients said during a news conference on Jan. 12 that CDC Director Rochelle Walensky recommends Americans to wear "a well-fitting mask," which can include multiple-layered cloth masks, N95s, K95s, or other types.

Zients added that N95 masks are currently "widely available" in the United States and the government "has a strong stockpile of over 750 million masks."

"One of the first things we did when we entered office was to significantly improve our manufacturing and stockpile of all PPE," he said.

Despite the change in the agency's mask recommendation, Walansky said that the CDC continues to advise Americans that any mask is better than no mask.

The latest CDC guidance notes that there is a special category of "surgical N95" masks that are specially designed for protection against blood splashes and other operating room hazards. Those are not generally available for sale to the public, and should continue to be reserved for health care workers, the agency said.

The CDC and health experts have evolved mask guidance's throughout the CCP (Chinese Communist Party) virus pandemic.

In an earlier update, CDC officials said disposable N95 masks could be used in certain situations if supplies allow it. The agency included being near a lot of people for extended periods of time on a train, bus, or airplane; taking care of someone in poor health; or being more susceptible to severe illness.

Compared to more commonly worn surgical masks or cloth face coverings, when worn properly, N95s fit more closely to the face and provide at least a 95 percent protection level against airborne viruses, according to the CDC.

Meanwhile KN95s, which work similarly to N95 masks, are regulated by Chinese authorities. They were authorized by the CDC as a suitable alternative for N95s due to shortages during the onset of the pandemic last year, although some have previously raised concerns that the majority of non-certified KN95 masks from China do not meet U.S. standards for effectiveness.

Earlier this week, President Joe Biden said the government will launch an effort soon to make "high-quality masks" available to Americans for free.

"So, next week, we’ll announce how we’re making high-quality masks available to American people, the American people, for free," said Biden, who wasn’t wearing a mask while speaking inside the Eisenhower Executive Office Building in Washington on Jan. 13.

The Biden administration, which has been grappling with a surge in COVID-19 cases and hospitalizations in recent weeks, is responding by expanding access to COVID-19 tests and sending military medical teams to hospitals, among other initiatives.
