On the one hand is the view shared by Dr. William Schaffner, a professor in Vanderbilt University’s Division of Infectious Diseases, who says that medical masks commonly worn by members of the public do not fit snugly around the nose, cheeks and chin.

David Hui, a respiratory medicine expert at the Chinese University of Hong Kong who studied the 2002 to 2003 outbreak of severe acute respiratory syndrome (SARS) extensively, says it’s “common sense” that wearing a mask would protect against infectious diseases like COVID-19.
“If you are standing in front of someone who is sick, the mask will give some protection,” Hui says. “The mask provides a barrier from respiratory droplets, which is predominantly how the virus spreads.”
He also says that the role of a face mask may be especially important in the epidemic due to the nature of the virus. Patients with COVID-19 often have mild or even no symptoms, and some researchers believe it can also be transmitted when patients are asymptomatic
