SAN DIEGO — Twelve additional cases of coronavirus were reported Tuesday by San Diego County public health officials, bringing the region’s total number of cases to 242.

The additional cases include the second death of a county resident and the first two cases of the illness in infants.

The resident who died was in their late-70s and had “many” underlying health issues, county Public Health Officer Dr. Wilma Wooten said. No further details on the death or infant cases were made available. A full report with all additional cases would be released later Tuesday, she said.

“We are seeing positive tests continue to rise,” San Diego County Supervisor Nathan Fletcher said.

“And due to increased testing, we should expect that to continue and even to accelerate. The reality is at this point we still don’t know how long we will continue on this trajectory.”

Wooten said she and other county health officials believed the crest of cases had not yet passed. On Tuesday, county data showed 242 cases, an increase of 12 from the day before — the fewest additional daily cases in nearly a week.

Wooten reminded people who are showing symptoms that unless they were extremely ill, to stay at home and avoid going to a hospital to help save beds for an influx of patients.

“Eighty-one percent of those who get COVID-19 have mild to moderate symptoms,” Wooten said.

Wooten said that if you were exhibiting symptoms, it was safest to self-quarantine if possible, and avoid leaving the home until three days after the last signs of a fever or cough, and at least a week after the initial onset of symptoms.
