SAN FRANCISCO, Calif. (KRON) — The California Department of Public Health created a COVID-19 watchlist to better monitor the novel coronavirus by each county.

CDPH is working with local health departments to identify what steps need to be taken to help mitigate the spread of the virus.

Bay Area counties currently being monitored, are:


Alameda County was added to the states monitoring list on July 12 after seeing an increase in COVID-19 cases recently.

Alameda County Health Services say that the increase in cases are due to people interacting with others while not wearing a face covering or not following physical distance.

Contra Costa

Contra Costa County is experiencing elevated disease transmission and increasing hospitalization. There is a concerning rise in the number of people hospitalized. This is in parallel to a rise in overall cases.


Marin County is experiencing elevated disease transmission, increasing hospitalizations, and limited hospital capacity. Drivers of this include county experiencing an outbreak at San Quentin State Prison within their jurisdiction; increased community transmission among essential workers; and outbreaks in congregate settings and Latinx neighborhoods
