While everybody from local drug stores to Amazon are selling out of surgical masks, the Center for Disease Control says you don't need one to prevent catching the dreaded Coronavirus or COVID-19.

From the CDC webpage:

CDC does not recommend that people who are well wear a facemask to protect themselves from respiratory illnesses, including COVID-19. You should only wear a mask if a healthcare professional recommends it. A facemask should be used by people who have COVID-19 and are showing symptoms. This is to protect others from the risk of getting infected.
