The County Health and Human Services Agency is reporting a sharp increase in new COVID-19 cases, adding 3,653 new cases in a single day today. This is the highest number of new cases reported since Jan. 7 of this year, when 4,550 cases were reported.

County health officials attribute the spike in cases to holiday gatherings and the more contagious Omicron variant.

While the majority of cases in the region are still Delta variant infections, an additional 69 Omicron cases were reported in the past week (Dec. 22 through Dec. 28), bringing the region’s total of known Omicron variant cases to 91.

Testing Resources

While testing demand is high, the overall testing system has the capacity to meet demand. Testing is available throughout the region, including at County testing sites and neighborhood pharmacies.

The County is recommending that people worried about COVID-19 infection and others seeking COVID-19 testing not go to a hospital to be tested, unless they have severe symptoms. This preserves hospital resources for patients who are critically ill.

Those with mild COVID-19 symptoms or other COVID concerns should contact their health care provider via phone or telehealth for guidance. Rapid antigen tests, which are available at many local pharmacies, are a good option if a testing site is unavailable.

Here’s a list of other locations where people can get COVID-19 tests.

Avoid Getting Sick

Meanwhile, County health officials are urging San Diegans to take every precaution necessary to avoid getting sick and slowing the spread.

“Given the significant uptick in COVID-19 cases, the continued spread of the more contagious Omicron variant, and the increased risks of spread that come with gathering with others, San Diegans must continue to make decisions with their own health and the public’s health in mind,” said Cameron Kaiser, M.D., M.P.H., County deputy public health officer. “As we close out this difficult year, the best resolution we can make for 2022 is to rededicate ourselves to the public health strategies that have been proven to work.”

Those strategies include:

  • Wearing the right kind of mask and wearing it correctly
  • Limiting indoor activities when gathering with people outside your household
  • If you have symptoms, get tested whether you’ve been vaccinated or not, and isolate until results are known
  • If you test positive, stay home, isolate and seek treatment if necessary

San Diegans who have not been vaccinated, or are overdue for their booster, are strongly encouraged to get vaccinated as soon as possible. There are more than 400 vaccination sites across the county, including at pharmacies, medical providers, clinics and County locations.
