23 – Source Control

Source control focuses on covering the nose and mouth to keep your respiratory droplets out of the air because this is the main way that the virus that causes COVID-19, SARS-CoV-2, gets from person to person. Masks that fit snuggly around the cheeks and our chin are the main way to do source control for COVID-19. A mask that fits well covers your nose and your mouth and blocks those respiratory droplets which are traveling in the air when you breathe, and which have virus in them if you’re infected. This means that those droplets when they’re covered up with that mask are much less likely to reach other people around you and then infect them.
