Since the start of the coronavirus outbreak some places have fully embraced wearing face masks, and anyone caught without one risks becoming a social pariah.But in many other parts of the world, from the UK and the US to Sydney and Singapore, it's still perfectly acceptable to walk around bare-faced.
-
the official advice from the World Health Organization has been clear. Only two types of people should wear masks: those who are sick and show symptoms, and those who are caring for people who are suspected to have the coronavirus.

a mask is not seen as reliable protection, given that current research shows the virus is spread by droplets and contact with contaminated surfaces. So it could protect you, but only in certain situations such as when you're in close quarters with others where someone infected might sneeze or cough near your face.
