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 when in the community can prevent transmitting droplets. Most community members should not wear medical masks, which should be reserved for health care workers. Heath care systems need to optimize supply of N95 Respirators. Cloth face masks are a useful alternative that can be made at home.
