The county Health and Human Services Agency reported 388 new cases of COVID-19 and 10 additional deaths Thursday.
Thursday's data increased the county's cumulative totals to 379,629 infections and 4,311 deaths since the pandemic began.
A total of 28,103 new tests were reported to the county on Thursday, and the percentage of new positive cases over the past week was 3.2%, according to the county.
San Diego County public health officials said Wednesday they were supporting those choosing to get COVID-19 vaccination boosters, following California Department of Public Health recommendations for those 18 and older.
People who completed the Pfizer or Moderna vaccine series more than six months ago are eligible for a booster shot. Those who received the Johnson & Johnson one-dose vaccine more than two months ago are also eligible to get a booster shot.
"I encourage everyone who is eligible for a booster to make time soon to get their shot," said Dr. Wilma J. Wooten, county public health officer. "As we begin to attend more gatherings for the holidays, the booster dose can help better prevent infection and slow the spread of COVID-19."
The number of coronavirus patients in San Diego County hospitals decreased by 16 to 261 Wednesday, and the number of those patients in intensive care increased by five to 85, according to state data.
The number of county residents who have received at least one shot of a COVID-19 vaccine is now nearly 2.61 million — or 82.9% of residents 5 and older. More than 2.33 million, or 74.3%, are fully vaccinated. Close to 345,000 San Diegans 18 years of age or older have received a booster dose.
