Can face masks help prevent the spread of the coronavirus that causes COVID-19? Yes, face masks combined with other preventive measures, such as frequent hand-washing and social distancing, help slow the spread of the virus.

So why weren’t face masks recommended at the start of the pandemic? At that time, experts didn’t yet know the extent to which people with COVID-19 could spread the virus before symptoms appeared. Nor was it known that some people have COVID-19 but don’t have any symptoms. Both groups can unknowingly spread the virus to others.

These discoveries led the U.S. Centers for Disease Control and Prevention (CDC) to do an about-face on face masks. The CDC updated its guidance to recommend widespread use of face coverings to help prevent transmission of the virus by people who have COVID-19 but don’t know it.

Asking everyone to wear masks can help reduce the spread of the coronavirus by people who have COVID-19 but don’t realize it. And countries that required face masks, testing, isolation and social distancing early in the pandemic seem to have had some success slowing the spread of the virus.

Here are a few pointers for putting on and taking off a mask:

  • Place your mask over your mouth and nose.
  • Tie it behind your head or use ear loops and make sure it’s snug.
  • Don’t touch your mask while wearing it.
  • If you accidentally touch your mask, wash or sanitize your hands.
  • Remove the mask by untying it or lifting off the ear loops without touching the front of the mask or your face.
  • Wash your hands immediately after removing your mask.

N95 masks

Actually a type of respirator, an N95 mask offers more protection than a surgical mask does because it can filter out both large and small particles when the wearer inhales. As the name indicates, the mask is designed to block 95% of very small particles. Some N95 masks have valves that make them easier to breathe through. With this type of mask, unfiltered air is released when the wearer exhales.

Health care providers must be trained and pass a fit test to confirm a proper seal before using an N95 respirator in the workplace. Like surgical masks, N95 masks are intended to be disposable. However, researchers are testing ways to disinfect N95 masks so they can be reused.
