The Marin County COVID-19 Status Update is now publishing five days a week (Monday through Friday) and as needed, in order to share important news and resources in our battle against COVID-19 and to keep our economy running. We remain here for you.


💩 Researchers Look to Sewage and Wastewater to Monitor COVID-19

It’s no secret: everybody poops. Marin County Public Health has partnered with local sanitary agencies and University of California Berkeley to do regular sampling of wastewater supplies in Marin County as part of broader COVID-19 outbreak surveillance. Anyone that is infected with COVID-19 is emitting the virus in their bodily fluids, which ends up passing as waste in the toilet. UC Berkeley scientists can detect RNA for the virus in wastewater. Dr. Matt Willis explains more about how the research project works and why its an important tool for the long-term response to COVID-19.

In Other News… (Non-COVID Updates)

While the following is not related to COVID, it is news from Marin County's Emergency Operations Center that we thought you should know about.


Participate in the Great Shake Out: COVID-19 Style.

Great ShakeOut Earthquake Drills, a worldwide earthquake safety movement, are involving 17.1 million people throughout 2020 (and counting). Most participate in ShakeOut by registering to practice “Drop, Cover, and Hold On,” and many do much more. Due to the COVID-19 pandemic, participants are adapting their ShakeOut activities through video-conferencing, choosing staggered or alternative dates, and following local health and safety guidelines (see

There is still time to join ShakeOut this year: register to participate on any day that works for you at Most take action on International ShakeOut Day each third Thursday of October, this year being October 15.  [Continue reading news release]


Spare the Air Alert extended through Thursday.

The Bay Area Air Quality Management District is extending the Spare the Air Alert due to wildfire smoke from the Glass Fire in Napa and Sonoma counties through Thursday, October 8, which bans burning wood, manufactured fire logs or any other solid fuel, both indoors and outdoors.

Wildfire smoke from the Glass Fire in the North Bay, in addition to smoke from other northern California fires, will continue to impact the region. While onshore winds will continue to blow smoke out of much the Bay Area, localized impacts near the Glass Fire and intermittent impacts in the broader Bay Area will continue. Expect Marin County’s AQI levels to reach Orange or “Unhealthy for Sensitive Groups” during this time.

Smoke from wildfires can affect health. The most common symptoms are eye and throat irritation, coughing, and difficulty breathing. Those with health problems, especially heart or respiratory conditions, should take extra caution.

Follow these precautions to protect your health:

  • Minimize outdoor activities.  Postpone/Reschedule intense outdoor cardio activities.
  • Stay indoors with windows and doors closed as much as possible.
  • Do not run fans that bring smoky outdoor air inside.
  • Run your air-conditioner only if it does not bring smoke in from the outdoors.
  • Avoid activities that create more indoor and outdoor air pollution, such as frying foods, sweeping, vacuuming, and using gas-powered appliances.
  • Consider leaving the area until smoke conditions improve if you experience symptoms related to smoke exposure.
  • Check on family, friends, and neighbors who may be sensitive to poor air quality and who spend much of their time alone.

Regarding Marin County’s October 6 data for the “Blueprint for a Safer Economy, yesterday’s Status Update incorrectly stated the new adjusted case rate as an “increase of 1.7 since last assessment,” when it should have read a “decrease of 1.7.” The web version of the October 6 Status Update has been updated to correct this typo.
