Holiday Precautions Urged as COVID-19, Omicron Cases Spike Up

San Diego, California - An increasing number of COVID-19 cases, more upcoming holiday celebrations and the growing spread of the Omicron variant are prompting County health officials to urge San Diegans to do their part to keep the coronavirus spread from increasing even more.

A total 1,856 COVID-19 cases were reported in the region on Dec. 21. A figure that high has not seen since Aug. 26, 2021, when 1,865 infections were reported.

Also, an additional 16 Omicron cases were reported in the past week (Dec. 15 through Dec. 21), bringing the region’s total of known cases to 22. Furthermore, the first hospitalization due to Omicron was reported in the region.

The County and the Hospital Association of San Diego and Imperial Counties today issued an advisory urging San Diegans to take every precaution necessary to fight the increase of COVID-19 cases and the accompanying stress on the medical care system.

“For those unvaccinated or in need of a booster, please get vaccinated now as an early New Year’s resolution,” Wilma J. Wooten, M.D., M.P.H., County public health officer, said in the advisory issued today. “I know many are weary of the pandemic, but we all need to pull together for one another and take the simple steps we know work, especially with the more transmissible omicron variant.”

Unlike the surge this time last year, the region now has plenty of COVID-19 vaccines and booster doses, which remain the best long-term protection against COVID-19 hospitalizations and deaths. The overwhelming number of people in the hospital with COVID-19 are San Diegans who are not fully vaccinated.

There are more than 400 vaccination sites that include pharmacies, medical providers, clinics and County locations, the region has the capacity to meet demand.
