For the first time in a month, Orange County’s COVID-19 hospitalizations exceeded 200 patients as health officials warned again Wednesday of a winter surge and an entire sixth-grade class in Yorba Linda was forced to quarantine and do its classwork online.

The county recorded 314 new infections and logged 10 more fatalities Wednesday, raising the cumulative case number from throughout the pandemic to 318,066 and the death toll to 5,839.

Hospitalizations increased from 194 Tuesday to 206 Wednesday, with the number of patients in intensive care ticking up from 63 to 64.

The county has 24.5% of its ICU beds available and 70% of its ventilators. Of those hospitalized, 87% are unvaccinated and 89% in ICU are unvaccinated.

Travis Ranch School sixth-graders were sent home and learning via Zoom this week after a breakout of “dozens of cases,” according to the Placentia-Yorba Linda Unified School District.

Dr. Regina Chinsio-Kwong, the deputy county health officer, said the outbreak was similar to others nationally.

“Most of the people were not vaccinated or partially vaccinated,” Chinsio-Kwong told reporters. “It would have helped if more people at the school were vaccinated.”

Orange County Health Care Agency officials were still investigating what happened, but, “What we do know is there was potentially one adult who was not vaccinated and symptomatic” on campus, Chinsio-Kwong said.

“And many of the kids in the classroom were not vaccinated,” Chinsio-Kwong said.

To play it safe, the district decided to opt for virtual education for the week, she said.

“Maybe it is helpful that we’re going into the winter break,” she said.

Of those in the newly eligible 5-to-11 age group, 18% have received at least one dose of vaccine in the county, Chinsio-Kwong said. Among the 12-to-17 age group the number stands at 70%, she said.

There are “at least 200,000” children 5 to 11 who still need to begin the vaccination process, Chinsio-Kwong said. And about 70,000 in the 12 to 17 age group still need to start getting vaccinated, she added.

“That’s still a significant portion of kids who need to get vaccinated,” Chinsio-Kwong said.

The newly discovered COVID variant, Omicron, is two to three times more contagious than the Delta variant, guaranteeing high odds of infection, she said.

“Don’t wait,” Chinsio-Kwong advised parents. “Omicron is out there. Please get ahead of it. Please get in line and get your vaccine today.”

No one should wait for a vaccine engineered for the Omicron variant, because that may take months to get through the approval process, she said.

“Right now, our best chance is again, if you’re eligible get fully vaccinated, and if you’re eligible, get your booster. And if you’re immunocompromised, please be careful,” Chinsio-Kwong said.

On the first day of the new state mandate to wear masks in indoor public spaces, Chinsio-Kwong said it was important for residents to make sure they wear a face covering with three layers and to wear it properly with a tight fit over the mouth and nose.

“The question I keep hearing from the public is what does `public’ mean,” she said. “Public is everywhere outside your private residence.”

The doctor also prescribed eating more healthy foods and avoiding stress and anxiety as well as checking up on family, friends and neighbors.

“We need to take care of ourselves, but we also need to take care of our community,” she said.

Of the fatalities logged Wednesday, two happened this month, raising the death toll to four so far. Seven happened last month, raising November’s death toll to 92. One dates back to January.

The death toll stands at 125 for October, 195 for September and 182 for August.

In contrast, the death toll before the more contagious Delta variant-fueled summer surge was 31 in July, 19 for June, 26 for May, 46 for April, 202 for March and 619 for February.

January 2021 remains the deadliest month of the pandemic with a death toll of 1,596, ahead of December 2020, the next deadliest at 985.

The case rate per 100,000 residents among the unvaccinated climbed from 14.4 on Nov. 27 to 24.2 as of Dec. 4, the latest figures available from the OCHCA. The case rate per 100,000 for vaccinated residents increased from 2.9 to 4.5 during the same time frame.
