SAN DIEGO — The number of COVID-19 cases in San Diego County increased by 84 to 603 Monday, but the number of deaths remained at seven.

The figures released Monday were skewed by the inability to send test results to the county government on weekends, according to Dr. Eric McDonald, San Diego County’s epidemiology director.

There are 118 San Diego County residents hospitalized because of the coronavirus, including 51 in intensive care, according to figures released by San Diego County.

The diagnoses announced Monday included a second San Diego Police Department officer, Mayor Kevin Faulconer said. Four San Diego lifeguards and one San Diego Fire-Rescue Department firefighter have also been diagnosed with the coronavirus, according to Faulconer.

The largest group of cases reported Monday was the 148 among people ranging in age from 30-39, while the second-largest was the 121 among people ages 20 to 29.

People between the ages of 20 and 49 make up 62% of the county’s cases. Four positive results have been found in children under the age of 9, including two infants. Twenty-nine residents over 80 years old have tested positive.

Of the 603 cases, 256 were female and 345 were male, with two patients listed as “unknown” in the data.

County health officials have seen the results for 8,129 tests, San Diego County Supervisor Nathan Fletcher said, but likely more had been performed before the county required the results of all tests to be reported.

Dr. Nick Yphantides, San Diego County’s chief medical officer, reported that four “congregate living sites” — which can be assisted living facilities, prisons or anywhere where large groups of people congregate in one living location — have tested positive for 33 cases and include two of the county’s deaths from the illness.

Those sites were under strict health protocols and under further investigation, he said.

The risk of contracting the coronavirus disease can increase from vaping and smoking, McDonald said.

“Any lung disease or condition would put you at risk,” McDonald said. “We don’t have specific cases so far, but our strong recommendation is to use this opportunity to quit.”

Despite concerns over hospital space, residents with cardio-vascular troubles or stroke symptoms should immediately seek emergency medical attention, Yphantides said.

“Don’t be reluctant to seek care if you need it,” he said.

The county will issue a new public health order extending indefinitely all closure orders that were set to expire Tuesday, Fletcher said.

The closure order applies to schools, nonessential businesses, restaurants, gyms and fitness centers, he said, and anyone 65 or older should continue to quarantine themselves at home.

Parks in Vista closed Monday in an attempt to limit the spread of coronavirus by encouraging social distancing. The North County city announced the decision on Sunday and had 10 confirmed cases of COVID-19 as of Saturday.

The closures include all parks, trails, public restrooms, the South Buena Vista off-leash dog area, athletic fields, basketball courts, pickleball courts, playgrounds, skate parks and tennis courts.

Carlsbad, Del Mar, Encinitas, San Diego, Solana Beach, Imperial Beach and the Port of San Diego closed all beaches, trails and parks in their respective cities early last week.

San Diego County health officials reported Sunday that five food handlers have tested positive for COVID-19 — four restaurant employees and a grocery store employee.

The grocery store employee who tested positive is from an Albertson’s store in Escondido, Fletcher said, adding that the store did the right thing by closing, alerting county environmental health officials, following sanitation protocols, then re-opening to customers.

“If you have a sick worker, they must stay home,” Fletcher said, urging employers to call 858-505-6814 to report any sick workers.

Co-workers of the Albertson’s employee who display any symptoms of the coronavirus infection will be sent home, but there are no tests pending in this case, McDonald said.

Health officials also stressed that there is no evidence of COVID-19 association with food. They cited the U.S. Centers for Disease Control and Prevention guidelines.

The county is increasing inspections of the many food facilities in the region, Fletcher said.
