Data Dashboards Now Provide Greater Clarity on San Quentin Numbers

The County of Marin has unveiled a refreshed look for its COVID-19 data webpage. Marin’s primary source for COVID-19 data, available at, now includes new charts that provides greater clarification of COVID-19 activity between Marin residents and people incarcerated at San Quentin. This includes a new chart that illustrates daily census of COVID-19 patients in Marin County hospitals during the COVID-19 pandemic, distinguishing Marin resident cases from San Quentin cases and identifying related impacts on local Intensive Care Units (ICU). Marin’s map charting cases across the County has also been updated to reflect current San Quentin numbers.

While the state’s California COVID Assessment Tool (CalCAT) groups data for Marin residents and San Quentin population together, Marin Public Health chose to list data for the two groups separately. COVID-19 cases occurring in the community have different implications for community spread and health department contact tracing compared to cases occurring in San Quentin State Prison.

“Every outbreak has its own characteristics, and we need to look at each separately to tailor prevention, outreach, and treatment to each setting,” said Dr. Matt Willis, Marin’s Public Health Officer. “We’re always sorting the data to learn where the virus is circulating and to guide our response. We think it’s important for our community to see these patterns with as much detail as we can offer.”

Other data sets available on Marin’s Data & Surveillance page include:

  • Daily Trends: review total cases, recovered cases, hospitalizations and deaths by the date they were reported.
  • Percent Positive by Test Date: review Marin’s percent positive test trends during the pandemic and 14-day average.
  • Positive and Negative Results:  compare the number of positive to negative tests based on the date the tests were performed.
  • Newly Reported Cases: browse trends in newly reported positive test results by the date the results were reported.   
  • Daily Tests Conducted: see how many tests were performed daily and a 7-day rolling average of tests performed.
  • Cases by Geographic Location: review an interactive map that shows the cumulative number of confirmed COVID-19 cases and the rate of cases per 100,000 residents by city/community in Marin County, including San Quentin prison.
  • Trends by Age, Gender, and Race/Ethnicity: compare demographic information for confirmed cases, hospitalizations and deaths, and see which groups may be more impacted by COVID-19 than others.
  • Other Impacts: In addition to reviewing documented cases of COVID-19, review data tracking deaths from any cause and severe respiratory illness to see early signs of how COVID-19 might be affecting Marin County.

“The fight against COVID-19 is far from over and we need our residents to remember that the virus is continuing to spread,” said Benita Mclarin, Director of Health and Human Services. “This data helps inform decisions within each community, including when travel may be allowed once again or when certain business industries can reopen.  We want to make sure our residents understand the status of COVID-19 in their local area.”

COVID-19 cases occurring in San Quentin State Prison are formally under the jurisdiction of the State of California and the California Department of Corrections. Marin County Public Health supports and collaborates with San Quentin State Prison during outbreak responses at their request. For up to date information on COVID-19 in state run correctional facilities please visit the CDCR Population COVID-19 Tracking Report.

UPDATED INFO! Reporting Public Health Order Violations

We know this is a challenging time. Those wishing to report a public health order violation by a business can submit their concerns to Please include the business name, address, and as much detail as possible regarding the perceived health order violation. Reports will be forwarded to the appropriate governing agency for review and investigation.

Visit Marin Recovers Status list for information on business openings and guidelines and the current health order for information on face covering requirements, shelter-in-place and more. Keep in mind that the goal of the order is to educate and keep our community safe. While violations of the public health order are misdemeanors, making arrests continues to remain a measure of last resort for local law enforcement. It will only be considered after all education and voluntary compliance efforts have failed.

Be a role model and follow the order while encouraging others to do the same. If you see a business out of compliance, you can speak directly to the owner, and offer the link or a copy of the COVID-19 Site-Specific Protection Plan as well as information about the Marin Recovers website. We’re all in this together and we all need to do our part.
