The patient load in the county’s hospitals has been building day to day from 188 on Dec. 20 to 215 on Dec. 21.
Hospitalizations inched up from 1,071 on Wednesday to 1,072 on Thursday, but then soared to 1,154 on Friday, with the number of intensive care patients rising from 168 to 171, according to the Orange County Health Care Agency.
The county also logged 8,257 new positive COVID-19 tests Friday, increasing the cumulative total since the pandemic began to 430,675.
The county has 19.6% of its ICU beds available and 63% of its ventilators. Of those hospitalized, 86% are unvaccinated and 87% in the ICU are not inoculated, according to OCHCA.
“It’s good hospitalizations have plateaued — I’ll take that all day long,” Andrew Noymer, an epidemiologist and UC Irvine professor of population health and disease prevention, told City News Service on Thursday.
“But it’s too early to do a victory lap,” he added. “I was pretty sure this summer Delta (variant) would peak higher than it did. I actually don’t think that it is inconceivable that we’re finding the peak, but just for one day — you’ve got to give me more than that.”
No matter how much higher hospitalizations may go, the death toll may not match prior surges, Noymer said.
“I do think the mortality will be less,” he said. “First of all, Omicron is milder, which is not to say for the unvaccinated it’s anything to sneeze at, but Omicron is less severe clinically and even more so for the vaccinated but, also ventilation use is down and hospital stays are less number of days on average.
“This is not a silver lining, per se, but it’s a fact that there will be fewer deaths for hospitalized patients this time around compared to last January. But we’re all really in a wait-and-see period, so I’m not calling the peak.”
The county’s adjusted daily case rate per 100,000 residents inched up from 103.4 on Thursday to 108 Friday. The testing positivity rate inched up from 26.8% to 27.5%, and increased from 29.8% to 31% in the health equity quartile, which measures underserved communities hardest hit by the pandemic.
The number of fully vaccinated residents in Orange County increased from 2,341,562 last week to 2,357,761, according to data released Thursday.
That number includes an increase from 2,189,337 last week to 2,205,067 of residents who have received the two-dose regimen of vaccines from Pfizer or Moderna.

In the relatively recently eligible age group of 5 to 11 years old, the number of children vaccinated increased from 46,791 to 52,803 versus 215,777 who have not gotten jabbed. It’s the least vaccinated age group in Orange County. The next-worst vaccinated age group is 25 to 34, with 314,619 inoculated and 144,782 who have not gotten a shot.
The most vaccinated age groups are seniors.
The seven-day case rate per 100,000 for residents not fully vaccinated increased from 212.9 as of Jan. 1 to 290.1 on Jan 8, the latest data available. The case rate for the fully vaccinated without a booster shot increased from 189.2 to 220.4, and the case rate for the fully vaccinated with a booster went up from 72.2 to 91.9.
As of Thursday, the Orange County Jails had 178 infected inmates, 44 from newly booked inmates.
The county logged five more COVID-related deaths on Friday, including the first for 2022. One occurred in December.
The death toll for the new year stands at four.
The death toll for December is now 65. Deputy county health officer Dr. Regina Chinsio-Kwong said last Friday that 50 of those who died in December were unvaccinated and seven were seniors.
November’s death toll stands at 103. October’s death toll stands at 127, with 196 for September and 182 for August.
In contrast, the death toll before the Delta variant fueled a summer surge was 31 in July, 19 for June, 26 for May, 47 for April, 202 for March and 620 for February.
January 2021 remains the deadliest month of the pandemic, with a death toll of 1,598, ahead of December 2020, the next deadliest with 985 people lost to the virus.
