How do face masks protect against the spread of COVID‑19?

Parent helping child with maskCOVID‑19 spreads from person-to-person, meaning that it can spread when an infected person coughs, sneezes or talks in close contact with another person. To help prevent this spread, the Centers for Disease Control and Prevention (CDC) recommends wearing a well-fitted face mask over your nose and mouth as one way to prevent the spread of COVID‑19.

Some types of masks may provide more protection than others, but any face mask is better than no mask if you choose to wear one.

"The main purpose of using a mask is what we call source control," says Carla Garcia Carreno, M.D., Pediatric Infectious Disease Specialist at Children's Health℠. "This means that the person who is wearing a mask will prevent spreading respiratory particles into the air and to other people."

Wearing a face mask is an additional step that can help prevent the spread of COVID‑19. It's important to still take other precautions.

Who should wear a face mask – and when?

The CDC recommends that all people ages 2 and older wear a face mask when in public indoor places if you live in an area with a high COVID‑19 community level. You can check your COVID‑19 community level on the CDC website. You may choose to wear a mask more often if you are immunocompromised, at high risk for severe illness or not fully vaccinated.

"Families should choose whether or not to wear a mask based on their local COVID‑19 community level, risk for severe disease and personal comfort level," says Dr. Garcia Carreno. "Parents should also check with their pediatrician for further guidance since they will know your child’s medical history."

In addition, you should always wear a mask if you have symptoms of or test positive for COVID‑19 and need to be around others. Learn more about recommendations of when to wear a mask. It’s important to know that guidance may change if cases rise or a new variant spreads.

How do I properly wear a mask?

When wearing a mask, make sure it:

  • completely covers your nose and mouth
  • fits snugly on your face and is secured
  • includes multiple layers of fabric
  • is breathable
  • can be washed and machine dried without changing shapes

When removing your mask, avoid touching your eyes, nose and mouth and wash your hands immediately after removal. You should also routinely wash your face mask after use if its washable.
