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.
Marin COVID Level and Mask Choices
Dr. Matt Willis takes a fieldtrip to Central Marin Sanitation Agency and explains how local COVID wastewater levels and hospitalizations describe current COVID risk for the community. Marin COVID Level is a new index, using local data sources, for timely and accurate information to guide personal COVID precautions.
State-mandated masking ends this week
On April 4, high risk settings such as hospitals will no longer be mandated by the state to require face covering indoors. However, many institutions in Marin will continue to require masks in certain settings. Marin COVID Level is medium, signifying ongoing transmission within the community and hospitalization rates matching historical averages. Residents accessing healthcare settings should be aware of and respect institutional policies to prevent virus spread.
XBB variant gaining dominance in Marin
Marin County laboratory surveillance has revealed that the XBB strain of SARS-CoV-2 has emerged as the dominant local strain. Of the past 16 local samples analyzed in the last month, 14 (88%) were the XBB strain. This follows national trends and ends a several month interval where three main varieties—XBB, BA.5, and BQ—were equally prevalent. This bivalent booster has proven efficacy against XBB.
Marin County Ranked Healthiest in State, while gaps remain
This week, results of the annual Robert Wood Johnson Foundation County Health Rankings were released. Marin County was ranked the healthiest among California’s 58 counties, based on factors like life expectancy, access to high quality healthcare, and air and water quality. However, a single ranking can hide important disparities within Marin and important gaps remain. Addressing health inequities is a priority for Marin County Public Health.
