Masking & Prevention :: Public Health :: Contra Costa Health

Wearing a well-fitted, high-quality mask (KN94/95 or N95) is an easy way to help stop your respiratory droplets from reaching others and to avoid breathing in droplets from others.

Masking is no longer required for the general public, but it is recommended when COVID levels are high. The CDC's COVID-19 community levels can help guide your decision on when to wear a mask.

Regardless of the CDC's COVID-19 community levels, the State of California recommends:

Not all masks provide the same protection. Wear a mask with the best fit, protection and comfort for you. No matter which mask you choose, make sure it fits well with no gaps.
