Los Angeles County has reported 5,055 new positive COVID-19 cases and 29 additional deaths since Saturday in its latest data.

The figures come as Los Angeles County’s public health director continues preaching caution against the spread of COVID-19 as holiday gatherings continue and an ongoing heat wave keeps many people indoors.

“As we all look forward to celebrating Labor Day and expressing our deep appreciation to the many hard-working people throughout our county, we face the twin challenges this holiday weekend of ongoing circulation of COVID, plus very high heat across most regions of L.A. County,” Public Health Director Barbara Ferrer said in a statement.

“With the extreme heat, it will make sense for many to move gatherings indoors. When gathering indoors, you can maximize ventilation by opening windows and doors, using air filters, and setting HVAC systems to maximize fresh air exchange,” Ferrer continued. “It is also advisable to wear a mask if gathering indoors with individuals whose COVID status is unknown.”

The latest figures raise the cumulative case total from throughout the pandemic to 3,418,798 and overall death toll of 33,209 in Los Angeles County.

The average daily rate of people testing positive for the virus was 7.5% as of Monday.

Ferrer has noted that the official number of new cases reported each day is an undercount of actual virus activity in the county, since many people rely on at-home tests, the results of which are not reported to the county.

There was no immediate update on the number of coronavirus patients in Los Angeles County hospitals. As of Saturday, that number had declined by 11 people to 777, with 93 of those patients in intensive care, up slightly from 91 a day earlier, according to the latest state data.

On Thursday the county officially moved into the U.S. Centers for Disease Control and Prevention’s “low” COVID-19 activity level, a result of the falling infection rate and continued slower pace of new virus-related hospital admissions.

The CDC moved Los Angeles County into the “low” category when the average rate of new COVID infections fell below the threshold of 200 per 100,000 residents. The official infection rate as of Thursday was about 193 new cases per 100,000 residents.

At some point this week, the county is expected to begin offering the newly approved COVID vaccine booster doses specifically engineered to combat the Omicron variant. The county anticipates receiving 170,000 doses of the new booster shots by the middle of the week, Ferrer has said.

The bivalent boosters were developed to generate an immune response from the original COVID-19 virus and BA.4 and BA.5 Omicron subvariants. A Pfizer/BioNTech booster is for those age 12 and over, while a Moderna bivalent booster is for those age 18 and older.

“Most Californians are now eligible for an updated Moderna or Pfizer-BioNTech booster and will be able to strengthen their protection against COVID-19 as we head into the fall and winter seasons,” California Health & Human Services Agency Secretary Dr. Mark Ghaly and state Public Health Director Dr. Tomás J. Aragón said in a joint statement issued Saturday.

“These boosters are bivalent, which means they are pulling double duty by increasing immunity against the original coronavirus strain while also protecting against the newer Omicron variants threatening Californians,” the statement continued. “Because protection from infection can decrease over time, the updated boosters are a safe way to maintain protection and reduce the most severe outcomes of COVID-19, such as hospitalization, long COVID, and death.”
