COVID-19 Status Update for 11/04/2022

Marin County COVID-19 Status Update: November 4, 2022

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.

Mental Health & Fentanyl Crisis

In this video Dr. Willis invites community members, leaders and parents to join us in tackling this Mental Health Crisis together. In the past two years of the pandemic, we have seen an increases in substance use and overdose.

Recent data from Marin County Public Health show that the county is on track for another record year of overdose related deaths. The trend is directly tied to the increased availability and use of the powerful synthetic opioid fentanyl. In response to the growing crisis, Public Health and the RxSafe Marin coalition are hosting a gathering of agencies, community members, parents, and school leadership to end preventable overdoses in Marin.

The Marin County Overdose Prevention Summit is scheduled for 4 p.m. Tuesday, November 15, 2022 at Embassy Suites in San Rafael (101 McInnis Parkway). Online registration is open for this free event. Space is limited.

Register for the event.

Rapid increase in BA5 sub variants in Marin 

After about four months with Omicron BA5 as the dominant pandemic strain in Marin, the pattern is changing again.  There were nine distinct subvariants found among the 15 samples reported this week. This is the largest number of distinct strains ever reported in Marin in a single week since the start of the pandemic. The pattern of increasing diversity of circulating strains is being seen globally. The updated booster is effective against Omicron BA5 and is expected to be effective against its “offspring”, which make up the majority of new strains. Marin County Public Health works closely with the California Department of Health to monitor the evolution of the virus to guide our pandemic response and will continue to provide updates.

Updated Booster is Preventing Serious Illness in Marin 

Preliminary data from Marin County show the updated booster formulation, first available September 1, is effectively protecting our residents. Of those over age 65 who are eligible, 45 percent have received the updated booster. There have been 22 hospitalizations in this age group over the same period - none of those hospitalized had received the updated booster. This means the hospitalization rate for those who have received the updated booster is zero in Marin, so far.

Residents who may have been waiting for more local, real-world evidence of the effectiveness of the updated booster now have it and should feel reassured. Find your updated booster at

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.
