Omicron Surge has Begun in Marin 

Less than one week after the first case of the Omicron variant was detected in Marin County, public health officials are witnessing the beginning of the anticipated surge of cases tied to the new variant.  This spike in cases is prompting Marin County Public Health to encourage action by both the public and local clinicians.  

112 new cases were reported in Marin County on Tuesday, December 21, the highest daily case count since January 13, 2021. The highest daily count during the summer surge driven by the Delta variant was 86. 

In Northern Europe and the Eastern United States, the Omicron variant overtook the Delta variant as the dominant strain over a short period of one to two weeks. That shift is now occurring in Marin.  

“We’re deep into the transition to Omicron” said Dr. Matt Willis, Marin County Public Health Officer. “Given the detection in Marin wastewater last week, increased number of confirmed cases regionally, yesterday’s spike in cases, and the emerging national data, we should assume new cases are most likely due to Omicron.” 

The Omicron variant is significantly more contagious than previous strains. This makes infection more likely to happen through encounters in indoor public settings, including social gatherings and even retail or restaurant settings. Continue reading the full news release


Marin Voice: Next Steps As Omicron Variant Spreads 

By Dr. Matt Willis (December 23, Marin Independent Journal) 

We’re at an important junction in our pandemic response. 

Just one week after detecting the first case of the new COVID-19 omicron variant in Marin County, we’re witnessing a surge in cases due to its spread in our community. This surge could be the largest since the start of the pandemic. 

While this is alarming, it’s important to ground our understanding in the best available evidence, as we have in every chapter of our response. 

Two critical features of omicron, neither of which is fully understood, will determine our pandemic experience over the coming weeks. These are the severity of illness caused by the variant and the level of protection offered by the COVID-19 vaccine.  Continue reading at 


A Call to Providers to Act On COVID-19 Prevention, Vaccination and Treatment Strategies  

Today, Marin Department of Health and Human Services issued a public health advisory to local healthcare providers in response to spread of the Omicron variant. With a spike in cases locally, healthcare providers should anticipate an increase in the volume of patients seeking advice or evaluation for COVID-19 infection.  

In sum, Marin Public Health is calling on local healthcare providers to take action in the following areas 

  • Prevention: Provide education to unvaccinated and unboosted patients regarding the risks associated with travel and indoor gatherings in light of Omicron. In addition, encourage frequent testing and emphasize the need for COVID-19 positive patients to properly isolate and notify close contacts.  
  • Vaccination:  All Marin primary and urgent care providers should enroll in California’s COVID-19 vaccination program (if they have not yet already) with the goal of offering clinic-based COVID-19 vaccines and boosters by early January. In addition, clinicians should identify unvaccinated and unboosted patients and offer a vaccine as soon as possible. 
  • Treatment: Stay abreast of the current COVID-19 treatment guidelines, including outpatient monoclonal antibody therapy and treatment.  

A recent survey of Marin residents found that most residents get tested for COVID-19 for symptoms, and most seek isolation and quarantine guidance from their health care provider. This finding reinforces the essential role that healthcare providers play as a trusted resource to patients during the pandemic response.
