Current evidence suggests that viral respiratory disease is spread via droplets from infected individuals. Infection can be spread prior to a person being symptomatic. Wearing a mask can reduce transmission of disease when individuals are in the community or caring for ill family members at home. Masks should be made with two or three layers of a breathable, tightly woven fabric and fit snugly around the nose and chin with no large gaps. Health care systems need to optimize supply of N95 Respirators.
