As we learn more about the nature of the coronavirus, evidence is mounting for the effectiveness of cloth face coverings in reducing its transmission. When we wear facemasks, the droplets and aerosols emitted when we cough, sneeze, laugh, sing or talk cannot travel as far. Coronavirus primarily is spread when these tiny, even microscopic particles containing the virus travel through the air and enter the eyes, nose or mouth of another person. Without a mask, droplets can travel six feet or more and aerosols can hang in the air. By wearing one, we limit the distance of any infectious particles travel to a few inches.
