Face coverings can be an effective means of slowing the spread of the infectious agent for many respiratory illnesses and may help slow the spread of COVID-19. Wearing a face covering does NOT provide complete protection and does not replace other ways of slowing virus spread such as:

  • Staying away from public places and group gatherings

  • Washing hands and using hand sanitizer often

  • Avoiding touching eyes, nose and mouth

• Practicing physical distancing


  • Masks and cloth face coverings should be handled assuming they are contaminated with the virus causing COVID-19.

  • Face coverings should be removed without touching the inside. They should be immediately placed with dirty laundry, or stored in a plastic bag until they can be properly cleaned.

  • Wash your hands after handling a used face covering or use hand sanitizer if hand washing is not an option. If possible, wash your face after removing a face covering.

• Cloth face coverings should be washed after each use. Follow CDC guidelines at


  • Proper use may restrict the spread of virus from an infected person, or prevent a healthy person from becoming effective.

• Facemasks are tested for their ability to trap viruses in respiratory droplets moving at high velocity, such as in a cough or sneeze.


  • Cloth face coverings can be uncomfortable to wear. A proper fit is tight over the nose, mouth and chin.

    • Shaving is not necessary for cloth face coverings or surgical masks.

  • Cloth face coverings can help reduce disease transmission but wearing one does not provide absolute protection.

  • According to CDC, wear cloth face coverings whenever interacting with the public or when caring for someone who is sick or may be infected.

  • It is not necessary to wear a face covering while at home or outside for exercise.
