March 8, 2021: Mask Remain Critically Important

MASKS REMAIN CRITICALLY IMPORTANT: GET THE MOST OUT OF YOURS

Wearing a mask is essential during the COVID-19 pandemic. Even if you are vaccinated you still need to wear a mask, it will help prevent both you and others from getting COVID-19. This is more important than ever with new, more easily transmitted variants of COVID-19 on the rise. 

 CDPH has issued Guidance on the Use of Face Coverings, which broadly requires the use of face coverings for both members of the public and workers in all public and workplace settings where there is a high risk of exposure.

 An effective mask has both good fit and good filtration. A well fitted mask has no gaps between the face and mask, such as above the nose or at the sides. With gaps, air that has virus particles can easily leak in or out around the sides of the mask. Good fit forces the air that you breathe out and breathe in to go through the mask and be filtered. Good filtration blocks the virus particles from going through the mask itself. You can get good filtration with the right materials and by using more layers.

 Good fit and filtration improve protection for others if you are infected and protection for you if you are exposed to an infected person.

 "Double masking" is an effective way to improve fit and filtration. A close-fitting cloth mask can be worn on top of a surgical/disposable mask to improve the seal of the mask to the face. Layering more than two masks is not recommended as this could be difficult to breathe through. Also, it is not recommended to wear two medical masks, or to wear a medical mask on top of a KN95 or an N95. Double masking may be appropriate where improved fit and filtration are especially important, and some situations where this may be considered are listed below.

 Regardless of the mask type, it is only effective if it is worn over your mouth and nose.
