Marin County Public Health Status Update for December 22, 2023, includes Rapidly Spreading Variant Likely Present in Marin; Fall Vaccine Progress; Pertussis Circulating in Marin; Travel Advisory: Dengue Fever; and COVID-19 Data Update. 

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.

Rapidly Spreading Variant Likely Present in Marin 

A fast-spreading COVID-19 variant, JN.1, now constitutes over 20% of cases nationally. Though not detected in Marin samples yet, it’s likely that JN.1 has begun to circulate locally. This could fuel a period of increased transmission lasting weeks. JN.1 is related to Omicron and shares symptoms and severity with existing strains. The current COVID vaccine remains effective against JN.1. 

Fall Vaccine Progress 

California's first pediatric flu death this season highlights the need to protect eligible residents from seasonal viruses. Older residents are at highest risk for mortality. As of this week, for Marin residents over age 60, 56% have received the flu shot, 49% received the COVID-19 vaccine, and 19% the RSV vaccine. While these are among the highest in the state, a majority of older residents are still unprotected. Visit  

Pertussis Circulating in Marin 

Pertussis, or whooping cough, is a vaccine preventable bacterial pneumonia that can cause death in infants. Eight pertussis cases have been reported to Marin Public Health this fall. While none were hospitalized, this signifies ongoing local transmission. From 2010-2015, Marin had among the highest pertussis rates in the nation. With increased vaccinations, Marin’s last outbreak was in 2018. Youth get their final pertussis vaccine in 7th grade as a school requirement. Pertussis vaccine is recommended for pregnant women and any adult in close contact with infants. Obtain the vaccine through your healthcare provider. 

Travel Advisory: Dengue Fever 

Marin residents traveling to tropical climates should be cautious of rising Dengue Fever risk. Dengue is transmitted through mosquito bites. Nearby destinations like Mexico have high infection rates, and California saw its first locally acquired case in Pasadena in October. The Pan American Health Organization attributes a regional surge to climate change and resource limitations, with 4.2 million cases reported.
