Caution - This mask is NOT rated for disease control. The Center for Disease Control (CDC) has provided the following information regarding homemade face masks: The role of facemasks is for patient source control, to reduce contamination of the surrounding area when a person coughs or sneezes. Patients with confirmed or suspected COVID-19 should wear a facemask until they are isolated in a hospital or at home. The new virus can be spread through saliva droplets emitted during a cough, sneeze, or even talking, and having a mask to capture those drops would presumably keep sick, especially asymptomatic, coronavirus carriers from spreading the disease. The CDC currently recommends keeping six feet apart, among other social distancing practices, and washing hands frequently and thoroughly for 20 seconds.
