The Centre for Disease Control (CDC) in the United States has warned that facial hair can interfere with face masks and respirators, which are being used around the world in an effort to combat the global spread of coronavirus, a.k.a 2019-nCoV.
The CDC has come up with an infographic, which displays assorted styles of beards, and showing the ones that are compatible with masks and respirators.
The main idea is that the hair should not cross the respirator sealing surface.
Health officials said some types of facial hair can keep the exhalation valve from working properly, Punch Healtheports, quoting the CNN News.
Styles such as side whiskers, handlebar mustaches, and several others are okay, but styles such as mutton chops and full beards are not recommended.
Punch reports that things like goatees and villain mustache are okay, with caution.
