SANTA ANA (CNS) — Orange County's COVID-19 hospitalizations dipped down Friday, offering more evidence of an easing of the delta variant-fueled surge.

Hospitalizations ticked down from 371 Thursday to 367 Friday, with the number of patients in intensive care increasing from 102 to 108, according to the Orange County Health Care Agency.

"Basically, we're looking pretty good, but, obviously, lower is always better, but we're considerably lower than earlier in the summer," Andrew Noymer, an epidemiologist and UC Irvine professor of population health and disease prevention, told City News Service on Friday. "We're as good as we expected to be, but I'd like to see lower still. I hope we're not finding a floor of 350 hospitalizations. I'm not a zero-Covid advocate. I don't think we're going to see zero Covid hospitalizations any time soon, but the numbers do look good to me and the percent positivity is down, which suggests we should find a lower floor sometime next week."

Noymer was disappointed that a Food and Drug Administration panel rejected a plan for proposed booster shots to the general public 16 and older.

"I'm in favor of boosters, so this is a big disappointment," Noymer said. "I don't know why they're being so cautious, honestly. I'm kind of shocked actually."

The weekly averages, released on Tuesdays, showed that the county's case rate per 100,000 residents dropped from 16 to 15.3, while the testing positivity rate fell from 5.4% to 4.7%.

The county's Health Equity Quartile positivity rate, which measures progress in the county's low-income communities, dropped from 5.8% to 5.1%.

The county had 20.7% of its ICU beds available and 64% of its ventilators.

The county logged seven more COVID-related deaths Friday, raising the cumulative total to 5,344. Six of the fatalities occurred in September, raising the death toll for this month to 18 so far.

One other fatality occurred in August, raising the death toll for last month to 133.

That figure stands in stark contrast to the rest of the summer.

The death toll for July was 22, 18 in June, 23 in May, 45 in April, 199 in March, 615 in February, 1,579 in January — the deadliest month of the pandemic — and 975 in December, the next deadliest.

The OCHCA also reported 394 new infections Friday, raising the cumulative total to 292,844 since the pandemic began.

There has been a recent jump in the number of infected inmates in the county's jails, but nowhere near what it was like during an outbreak in the winter wave in December.

The number of infected inmates jumped from 28 earlier this week to 50 on Thursday, with 39 in general population and 11 from newly booked inmates, said Assistant Sheriff Joe Balicki. It declined to 48 on Friday.

The rise in cases appears to be isolated two a dorm in the Men's Central Jail in Santa Ana and half of a barrack in the Theo Lacy Facility in Orange, Balicki said.

Sheriff's deputies are working closely with Orange County Health Care Agency officials on contact tracing and testing to tamp down the spread, Balicki said. Inmates are put into medical isolation of they test positive.

"In the past, these mitigation efforts worked very well for us," he said.

About 45% of the jail population is inoculated, Balicki said. Every inmate is offered a vaccine when booked and they are continued to be offered a shot during medical calls, he added.

Many of the positive tests are breakthrough infections of inoculated inmates, Balicki said. Many of the inmates who do test positive are asymptomatic.

Nine sheriff's employees are at home with infections.

The number of fully vaccinated residents in the county increased from 2,043,693 last week to 2,069,128 as of Thursday. That number includes an increase from 1,908,595 to 1,932,614 of residents who have received the two- dose regimen of vaccines from Pfizer or Moderna. The number of residents receiving the one-dose Johnson & Johnson vaccine increased from 135,098 to 136,514. 

There are 220,138 residents who have received one dose of Pfizer or Moderna vaccines.

According to the OCHCA, the largest distributor of inoculations is the agency, at 27.10%. CVS has dispensed the second most in Orange County at 18.10%. Walgreens has doled out 6% of the shots, just ahead of Kaiser Permanente at 5.6% and UC Irvine Health at 2.8%.

Walmart has inoculated 1.8% of Orange County residents, Safeway, Vons and Pavilions have doled out 1.20% of shots and the Families Together of Orange County has dispensed 1.1% of shots. All other health care providers were under 1%.

The county's case rate for fully vaccinated residents as of Sept. 11, the latest figures available, was 4 per 100,000, but 22.9 per 100,000 for the unvaccinated.
