Los Angeles County’s coronavirus hospitalizations increased by three people to 392, according to the latest state data released Saturday, while the number of those patients being treated in intensive care decreased by 18 to 41.

The latest numbers come one day after local health officials reported that COVID-19 mortality is down this year, though the impact of COVID-associated deaths remains “significant and concerning.”

An analysis by the Los Angeles County Department of Public Health found that a vast majority of increases in all-cause mortality were due to COVID-associated deaths. The agency said Friday it reviewed COVID and non-COVID mortality rates for four six-month periods from January through June, 2019 to 2022, and compared it to the 10-year period ending in 2019, prior to the pandemic — when the all-cause mortality rate had been stable with a slight downward trend.

According to the health department, when the pandemic began, the all-cause mortality rate for the first half of 2020 increased from just under 300 deaths per 100,000 people to almost 336 deaths per 100,000. In 2021, it increased even more significantly to almost 400 deaths per 100,000. During the first half of 2022, it dropped back to about 336 deaths.

The department said the majority of the increases were due to COVID-associated deaths but that COVID deaths did not account for all of the increase.

In addition, the pandemic may have led to more deaths from other causes through delayed care for other conditions, health systems being overwhelmed, or people being apprehensive about potential exposure to the virus, the agency reported.

According to Public Health Director Barbara Ferrer, “We’ll need to do a better job using all the resources available” to protect against severe illness, hospitalization and death for those who contract the coronavirus.

The department reported 1,017 new positive cases and 14 additional COVID-related deaths Friday. Health officials have noted that the majority of COVID fatalities involve elderly people and those with underlying health conditions, including heart disease, hypertension and diabetes.

The county logged a daily average of just under 920 cases of COVID-19 last week, a slight decrease over the average of about 950 the previous week.

Ferrer said Thursday that the number of new outbreaks in K-12 classrooms fell from 11 last week to seven this week, and continues to be of low concern.

The number of new outbreaks at skilled nursing facilities rose from seven last week to 13 and is now at medium concern level, but Ferrer noted that one positive case among a resident at a SNF is considered an outbreak.

Deaths linked to the virus averaged about 10 to 12 per day both this week and last week, Ferrer said.

Monitoring of viral concentration in wastewater showed a concentration of about 21% for the second straight week, placing that metric in the low concern category. Ferrer said a concentration above 30% would be a medium concern, and a number above 60% would be a high concern.

Ferrer added that Omicron BA.5 continues to be the most dominant subvariant of the virus, but “it appears to be gradually accounting for fewer sequenced specimens, indicating that other variants could become more dominant in the future.”

BA.5 accounted for 88% of sequenced cases for the week ending Oct. 1, compared with 91% the prior week and 93% a few weeks before that.

“These changes are small, but they could indicate the beginning of a growth advantage by some of the other strains,” including BA.4.6, which increased to almost 6% of sequenced cases in the most recent data, Ferrer said.

“Some of these mutations make it easier to evade prior immunity, meaning that many of us can be re-infected even if we were previously infected with a strain of Omicron earlier this year,” she added.

The variants can also break though protections such as vaccines and therapeutics, Ferrer said.

“The positive news is that the updated Pfizer and Moderna bivalent boosters contain the BA.4 and BA.5 spike protein, and we expect that this will provide good protection” against the variants, she said.

Ferrer also reported that as of Wednesday, Novavax was approved by the U.S. Food and Drug Administration as a booster for adults, meaning there are now three manufacturers for booster shots available.

Pfizer and Moderna offer bivalent mRNA boosters formulated to protect against the original COVID-19 strain and the Omicron variant, while Novavax offers a traditional protein-based formula similar to a hepatitis B or shingles vaccine. It is formulated for the original COVID-19 strain, “however it will likely provide some protection against Omicron, and it’s a good option for people who are unable or unwilling to take an mRNA vaccine,” Ferrer said.

The Los Angeles City Council voted Wednesday to continue the city’s emergency declaration due to COVID-19 for at least another 30 days.
