From here:
https://www.cdc.gov/coronavirus/2019...r-use-faq.html- The role of facemasks is for patient source control, to prevent 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 patient does not need to wear a facemask while isolated.
Why do medical workers wear masks if the patients are already sick? The masks work both ways. To help filter the pathogens and to prevent sick people from infecting others.
