MARTINEZ (CBS SF) — As COVID cases continue to spike in the Bay Area and California, Contra Costa County health officials on Tuesday issued a new health order requiring mask-wearing indoors in all public indoor places without exceptions.

To reduce spread, cases and hospitalizations, we all need to wear masks anytime we are in an indoor public setting.”
