The Marin County COVID-19 Status Update is published weekly and as needed to share important news and resources related to the COVID-19 pandemic response. We remain here for you.

Post-Holiday Bump in all Winter Viruses in Marin

Wastewater samples from January 4 confirm that over the Christmas and New Year’s holidays winter virus activity increased in Marin. Compared to the prior week, wastewater levels for COVID-19, Influenza, and RSV increased by 19%,13% and 88%, respectively. Flu and RSV levels had been declining through late December. COVID-19 wastewater levels continue their upward trend, to the highest measured levels since wastewater sampling was initiated in 2021. Marin County Public Health will be monitoring hospitalization rates closely to determine the impact of this trend on incidence of severe illness. This is a reminder that the risk of infection in our community remains high and is increasing. The best protection remains the vaccine. Please refer to our main COVID Surveillance page to view updated wastewater dashboards for COVID, Flu and RSV.

At-Home COVID-19 Test Expiration Dates Extended

The expiration dates for at-home QuickVue COVID tests provided by Marin County Public Health, have been extended four months. For example, those with expiration dates in February now expire in June. To confirm expiration dates, check the FDA handout: Quickvue At-Home OTC COVID-19 Test ( In addition, the California Department of Public Health endorses the use of all FDA approved over-the counter COVID-19 Tests beyond their original expiration date. To ensure your at-home test has not expired, follow these three easy steps. One, take the test. Two, wait the allotted time per the test instructions. Three, watch the control line appear. The visible control line indicates a good test. If the control line is not visible after waiting the instructed time, then the test has likely expired.

Monitoring Developments in China

China recently ended its "Zero-COVID" policy and reports indicate widespread surges in COVID cases and hospitalizations. While data are limited, it’s possible that millions of residents may be newly infected over a short interval, as the virus moves through previously unexposed and under-vaccinated populations. Booster vaccine access in China has been low. Genomic data suggests the BA.5 variant, which dominated in Marin through the summer and fall, is driving surges in China. The impacts on the global pandemic remain uncertain and will be monitored closely. Starting yesterday, January 5, the CDC is requiring travelers to the U.S. from China to show proof of a negative test.  

Know your COVID-19 Community Level

The CDC’s COVID-19 Community Levels are a tool to help communities decide what prevention steps to take based on the latest data. Levels can be low, medium, or high and are determined by looking at hospital beds being used, hospital admissions, and the total number of new COVID-19 cases in an area. Take precautions to protect yourself and others from COVID-19 based on the COVID-19 Community Level in Marin or other community in which you live, work or visit.

  • If you are at high risk of getting very sick, wear a high-quality mask or respirator (e.g., N95) when indoors in public
