The concept of wearing the protective covering over your nose and mouth is to reduce the risk of novel coronavirus transmission, especially for asymptomatic carriers. Such people can transmit the disease to others without showing any specific signs or symptoms. Apart from that, the protective covers act as a barrier in a closed space. So, when people present in the room talk, laugh, cough, or sneeze, they can transmit the disease to others via contaminated droplets. While immediate viral exposure is reduced when you wear such protective cover, its effectiveness depends on the type you choose and how you wear it.
