There is a currently circulating MYTH suggesting masks don’t work to prevent spread of COVID-19. The myth uses a @CDCMMWR published Sept 11, 2020 to back the assertion.

Ironically, the MMWR actually demonstrates the risks of not wearing a mask...

REALITY: Masks are recommended as a simple barrier to help prevent respiratory droplets from traveling through air and onto other people when the person wearing the mask coughs, sneezes, talks, or raises their voice. This is called source control. i.e. My mask protects you.

COVID-19 spreads mainly among people who are in close contact with one another (within about 6 feet), so the use of masks is particularly important in settings where people are close to each other or where social distancing is difficult to maintain.

The @CDCgov cites 19 peer-reviewed, scientific journals demonstrating the effectiveness of face masks as a means of source control, appearing in such journals as New England Journal of Medicine, Lancet, Science, Annals of Internal Medicine- from scientists across the globe.

So please understand- when you can’t guarantee social distancing, wearing a mask whenever and wherever you can is now widely recognized as an evidence based way to limit #COVID19 spread. 😷

Your mask protects me, and my mask protects you. Masks keep our country open! 😷
