While the Delta strain of COVID-19 remains dominant in the region, the County Health and Human Services Agency is reporting an additional four local cases of the Omicron variant, bringing the total to six.

The two previously reported cases were fully vaccinated and received their booster shots, while the four cases reported today were fully vaccinated but had not received booster shots.

Overall COVID-19 cases are also on the rise, with an additional 646 cases reported today.

“The holidays and colder temperatures mean San Diegans are spending more time indoors, where COVID-19 spreads more easily,” said Wilma J. Wooten, M.D., M.P.H., County public health officer. “I urge our community to continue taking the recommended precautions so that we can all have a safe and happy holiday season.”

In light of the increase in cases and hospitalizations, and the spread of the Omicron variant, the California Department of Public Health has implemented a new statewide mask mandate, which went into effect Wednesday.

The mandate requires that Californians age two and older wear a facial covering in all public indoor spaces. The indoor face covering mandate is scheduled to last at least through Jan. 15, 2022 and will be reevaluated.

In addition to wearing a mask indoors in public places, the following measures also help to protect against all varieties of COVID-19, including the Omicron variant:

  • Get vaccinated and get a booster if you qualify. The vaccine is widely available in the region, including at health care providers, retail pharmacies and community clinics. You can also make an appointment or find a site near you by calling (833) 422-4255 or visiting the My Turn website.
  • Wear a mask, especially in public indoor settings, regardless of vaccination status.
  • Get tested if you’ve traveled or have any symptoms, whether you’ve been vaccinated or not. You can make a free test appointment or find a walk-up test clinic at
  • Get CA Notify to receive alerts if you were in close contact with someone who tests positive for COVID-19.
  • Wash your hands frequently and stay home if you’re sick and distance yourself from others.
