Face Mask: Should everyone wear it to fight COVID-19 (READ DETAIL)

The Centers for Disease Control and Prevention (CDC) may soon agree with this assessment; the agency currently states that healthy people do not need to wear face masks unless they are caring for someone who is ill with the new coronavirus. But an anonymous federal official said that the CDC may change these guidelines, in effect encouraging people to cover their faces in public, The Washington Post reported on March 30.

That said, the public does not need to wear face masks most of the time, said Dr. Otto Yang, a professor in the Department of Medicine and the Department of Microbiology, Immunology and Molecular Genetics at the David Geffen School of Medicine at the University of California, Los Angeles.

If you're out for a walk - in essence, going to a setting where you can be at least 6 feet (1.8 meters) from other people, "then I think that not having a mask is fine and that fits the CDC recommendations," Yang said.

But, in his opinion, "If you have to be in a crowded situation, perhaps on a plane or waiting in line at the airport, it might make sense to wear a mask," Yang told Live Science.

The discussion about face masks has become a national conversation. Many people in the public are buying face masks to protect themselves. But health care experts have urged against hoarding, since these supplies are desperately needed in hospitals. Even the U.S. surgeon general tweeted "Seriously people - STOP BUYING MASKS!"
