COVID-19 Update to Board of Supervisors 

Dr. Matt Willis provided a brief update to the Board of Supervisors regarding the status of Marin County Public Health’s COVID-19 response. His update included a review of current COVID-19 case and hospitalization rates, vaccination progress.  Dr. Willis also covered the rollout of COVID-19 booster shots and the recommendation for older adults who are most vulnerable for breakthrough infection and hospitalization. Dr. Willis reviewed anticipated federal vaccine authorizations slatted to occur this month, including additional boosters and pediatric vaccines. 

Finally, Dr. Willis reviewed the criteria for ending the local mask mandate and safety tips for upcoming Halloween and Dia de Los Muertos celebrations.

Marin’s Community Transmission Rate Improves 

This afternoon, Marin moved into the “moderate” or yellow level of the CDC’s Community Transmission Tracker. Currently, Marin County is the only county in California with the yellow classification.  

This tracker is updated daily and looks at rates and testing positivity for the prior week. Because Marin County is on the margin of the orange (“substantial”) and yellow levels, we anticipate some fluctuation in rates, meaning Marin may move back to orange temporarily until our data stabilizes at a consistently lower rate.   

Marin County Public Health will continue to use the CDC tracker to monitor local transmission rates. This measurement is one of three criteria required to lift the local indoor mask requirement. If Marin remains in yellow for three weeks consecutively, the local indoor mask requirement will cease and default to the state’s current mask mandate. For more information about masking requirements and the full criteria to lift the local mandate, visit the masks and face coverings webpage.
