The number of coronavirus patients in Los Angeles County hospitals has fallen for 13 consecutive days, declining from 1,226 to 1,218 on Sunday.
The number of those patients in intensive care dropped from 368 to 360, according to state figures.
The county did not report daily COVID-19 case and death numbers Saturday or Sunday, with officials saying the health department was working on upgrades to its data processing systems. The data will still be collected, however, and will be reported this week.
On Friday, the department reported 50 coronavirus-related deaths and 2,024 new cases of COVID-19, bringing the county’s totals to 1,427,817 cases and 25,611 fatalities since the pandemic began.
However, officials also said Los Angeles County has seen three consecutive weeks of decline in its weekly infection rate, an improvement the public health director attributed in part to mask mandates and slowly rising vaccination numbers.
Under benchmarks set by the U.S. Centers for Disease Control and Prevention, transmission is considered in the “high” category if there are cumulatively 100 or more new cases per 100,000 residents over the course of a week. Much of the country is currently in the “high” transmission category.
Los Angeles County’s rate, however, fell last week to 104 cases per 100,000, a “welcome” 35% drop from the previous week, Public Health Director Barbara Ferrer said.
“This is the third week in a row we’ve seen decreases in our case rate,” Ferrer said. “Overall, we’ve seen a nearly 50% decrease from our peak of 204 cases per 100,000 people on Aug. 19. It’s worth noting that recent declines may reflect the masking requirements implemented early in the surge and the small increases in our vaccination coverage.
“Other parts of the country that don’t have masking requirements and don’t have as much vaccination coverage have not seen these significant declines in cases,” she said.
If the county’s rate continues to decrease and falls below 100 new cases per 100,000 residents over a seven-day period, it could move into the CDC’s less-severe “substantial” transmission category.
But Ferrer warned that a reversal of fortune could still occur.
“While we welcome the decreases, we do anticipate that with increased routine screening testing and intermingling at schools and worksites, along with Labor Day travel and gatherings, we do face the risk that our case numbers could once again increase,” she said.
Ferrer also again lamented the slow pace of vaccinations in the county. She said that over the past week only about 56,000 first doses were administered in the county.
“We are making very little progress,” she said.
Ferrer expressed hope that vaccination mandates like those announced Thursday by the Los Angeles Unified School District for eligible students 12 and over and by President Joe Biden for workers at large companies will have an impact.
Of the nearly 5.4 million fully vaccinated people in the county as of Sept. 7, 43,598 had tested positive, for a rate of 0.81%, she said. A total of 1,243 fully vaccinated people have been hospitalized, for a rate of 0.023% and 165 have died, for a rate of 0.0031%.
According to the most recent numbers, 75% of eligible county residents age 12 and over have received at least one dose of vaccine, and 66% are fully vaccinated. Among the county’s overall population of 10.3 million, 65% have received one dose and 57% are fully vaccinated. That population figure includes roughly 1.3 million people under age 12 who are ineligible for shots.
Black residents in the county continue to have the lowest vaccination rate, at 51% overall with at least one dose. Among Black residents age 12-15, just 35% have received at least one dose.
The average daily rate of people testing positive for the virus in the county was 2.6% as of Friday, down slightly from the previous Friday.
Meanwhile, the county last week announced it had identified 167 instances of the Mu variant of COVID-19 locally. But Ferrer said Friday that a lab reanalyzed samples dating back several months, and determined there have actually been 232 cases of the Mu variant locally, along with 28 instances of the Lambda variant.
While the Mu variant has raised eyebrows over concerns it could potentially evade vaccines, it has not yet risen to the level of being considered a “variant of concern” by health officials.
Ferrer said the highly infectious Delta variant is still the biggest threat, representing nearly 100% of all samples that undergo genetic sequencing to identify variants.
