Coronavirus Disease 2019 (COVID-19) is a viral disease cause by the SARS-CoV-2 virus. COVID-19 most often causes respiratory symptoms, but symptom severity and presentation can vary from person to person.

Face Coverings

You can buy or make face coverings, but keep in mind that different types of masks have different levels of protection. The Centers for Disease Control and Prevention (CDC) recommends people wear a mask with the best fit, protection, and comfort for them. To Learn more about face coverings, visit the CDC's Mask page.

Recommended Face Coverings

Face coverings should fit snugly over your nose and mouth and consist of multiple layers. If your mask or face covering only consists of one layer, consider doubling up. Information about choosing the right mask, and wearing it correctly, is available from the CDC. If you cannot buy face masks, you can: 

  • Make your own face covering. GetUsPPE has face covering patterns that have been reviewed by medical personnel.

Are clear face shields a good alternative to cloth face covering?

No, a face shield is not an acceptable substitute for a mask or cloth face covering because face shields do not fully cover the nose and mouth of the wearer, allowing air to freely escape or enter from the sides of the shield. People can wear face shields in addition to a mask or face covering to provide additional "splash" protection to the wearer from coughs and sneezes, but a face shield should never replace wearing a mask or face covering. 

How to Properly Wear Face Coverings

Proper use of face coverings impacts their effectiveness. If worn incorrectly or improperly, a mask will be less effective. Remember to wear a well-fitting face covering. 

  • Your mask should cover your nose and mouth at all times.
  • Always wash your hands with soap and water or use an alcohol-based hand sanitizer before you put on a face covering and after removing it.
  • Change your face covering when it gets moist.
  • Wash reusable face coverings after each use.
