Masks: Do they work, and how to use them right (or wrong!)
There may be some confusion around masks and how well they work to prevent the spread of a virus such as COVID-19. Some worry that masks just aren’t effective, also that they are uncomfortable, and even that carbon dioxide could build up in your mask as you breathe.
In the end, everyone from the Centers for Disease Control (CDC), major medical journals and associations such as the National Center for Immunization and Respiratory Diseases (NCIRD), Division of Viral Diseases , as well as the World Health Organization (WHO) have all reviewed the data and come to the conclusion that masks do in fact work.
We now know that transmission of the coronavirus can occur through respiratory droplets that are released when people speak, sneeze, or talk. Masks create a physical barrier to prevent these droplets from spreading into the surrounding air. But it also prevents you from breathing droplets that might already be in the air.
Masks also prevent transmission because you may accidentally touch a surface with the virus on it; then touch your nose or mouth, and these areas are portals for entry of germs. The bottom line is that research demonstrates, face masks are recognized as one of the most affordable and effective ways to slow the spread of the virus.
But, there is a correct way to use masks and an incorrect way. From the CDC content below, please review these RECOMMENDED and NOT RECOMMENDED mask solutions.
Non-medical disposable masks
Masks that fit properly (snugly around the nose and chin with no large gaps around the sides of the face)
Masks made with breathable fabric (such as cotton)
Masks made with tightly woven fabric (i.e., fabrics that do not let light pass through when held up to a light source)
Masks with two or three layers
Masks with inner filter pockets
Masks that do not fit properly (large gaps, too loose or too tight)
Masks made from materials that are hard to breathe through (such as plastic or leather)
Masks made from loosely woven fabric or that are knitted, i.e., fabrics that let light pass through
Masks with one layer
Masks with exhalation valves or vents
Wearing a scarf/ski mask as a mask
