The Marin County Public Health Status Update is published weekly to share news and resources related to pandemic response and recovery, emergency preparedness, and other public health priorities.

RSV Season Begins in Marin 

The amount of Respiratory Syncytial Virus (RSV) in Marin County wastewater has increased five-fold in the past two weeks. This signifies the onset of RSV season, with increased risk of exposure expected to last through fall and winter. RSV can cause severe respiratory illness among infants and older residents. In Marin, only 8% of eligible residents over age 60 have gotten the new RSV vaccine. The vaccine is highly protective starting about one week after receiving the shot.  

Combatting the Fentanyl Crisis with Education  

Accidental drug overdose is the leading cause of death in residents aged 55 and under in Marin. Fentanyl is responsible for most deaths, especially for those under age 25. On November 7, Marin County Office of Education and OD Free Marin, in collaboration with Song for Charlie, are hosting an in-person screening of “Drugs in the Age of Fentanyl” followed by a panel discussion. Topics will include how to talk with your children about this emerging threat, steps being taken in Marin, and how to protect yourself and loved ones. RSVP here.  

Preparing for a Global Gathering  

San Francisco is hosting the 2023 Asian Pacific Economic Cooperation (APEC) conference November 11-17. APEC members include 21 of the world’s major economies. The event will bring dozens of dignitaries into the region along with their motorcades, and parts of San Francisco will be closed to traffic. Marin County Public Health is engaged with hospitals and emergency response agencies to mitigate risks associated with this global gathering. Residents should stay connected to AlertMarin for relevant updates.  

Dengue Found in CA – a Rare Mosquito-Borne Illness  

Two locally acquired dengue cases have been reported in Southern California. Efforts are underway to reduce mosquito breeding sites and raise awareness of dengue symptoms, as local transmission in California had never occurred before. With a warming climate, the range for mosquitoes that carry tropical diseases is expanding northward. Prevent dengue and other mosquito-borne illnesses like West Nile Virus by avoiding mosquito bites and following CDC’s recommendations on how to control mosquitos inside and outside of your home. 

Mobile Mammography Promotes Access to Screening 

Breast cancer screening can detect disease early when it’s more easily cured. Mammogram rates are lower among low-income women in Marin, partly due to reduced access to radiology services. A mobile mammography vehicle supported by Partnership HealthPlan recently visited Ritter Center and Marin City Health and Wellness Centers, screening 71 low income or unhoused women for breast cancer in two days. This highlights the value of innovative approaches to close gaps in healthcare access in our community.
