Los Angeles County continues to see a rapid increase in COVID-19 transmission throughout the county, with cases having doubled in the past 10 days as the Delta variant spreads.
The Los Angeles County Department of Public Health on Thursday confirmed 2,767 new cases of COVID-19, an 80% increase from last week, according to the department.
As of Friday, 3,058 more cases were reported, marking the third day in a row with more than 2,500 cases reported in one day, according to Public Health.
The county’s average daily case rate, with a 7-day lag, is now 12.9 cases per 100,000, an increase from the rate of 7.1 cases per 100,000 last week.
There are 645 people with COVID-19 currently hospitalized and 22% of those people are in intensive care. Last week, 406 people were hospitalized with COVID-19 illness.
“Public health has detailed the increase in the Delta variant among strains sequenced in the Los Angeles County area for weeks,” department officials said. “While emerging data asserts that fully vaccinated people are well protected against serious infections with Delta variants, people with only one vaccine are not as well protected, and there is growing evidence only a small number of fully vaccinated individuals can become infected and can become infected. capable of infecting others.
From July 11 to July 17, the number of Delta variants sequenced was 201.84% of all sequences collected that week.
This is consistent with Delta’s rise nationwide: Earlier this week, the Centers for Disease Control and Prevention (CDC) estimated that Delta strains accounted for 83% of circulating COVID-19. Since an estimated 4 million people in LA County are yet to be vaccinated, the risk of further spread of this variant in LA County remains high, according to public health.
As of July 18, more than 10,845,531 doses of a COVID-19 vaccine have been administered to residents of Los Angeles County. Of these, 6,013,569 were first doses and 4,831,962 were second doses.
88% of people aged 65 and over in LA County, 70% of residents 16 and over, and 69% of residents 12 and over received a dose of the vaccine, including 39% of teens in LA County aged 12 to 17.
Of the nearly 10.3 million people in LA County, including those not yet eligible for the vaccine, 52% are fully vaccinated and 59% have received at least one dose.
“As more and more people have been vaccinated, the proportion of total cases among those vaccinated has also increased,” public health officials said. “This is to be expected because as more and more people are vaccinated, the number of fully vaccinated people who become infected will increase.”
In June, fully vaccinated people accounted for 20% of all diagnosed cases among LA County residents, while unvaccinated and partially vaccinated people made up 80% of cases.
According to estimates from Public Health, if the 52% of county residents who are fully vaccinated were not vaccinated, the number of new cases might be double because everyone would instead have the same risk of infection as the unvaccinated people. As the number of counties has grown, it would be much higher if there weren’t so many fully vaccinated people.
In Los Angeles County, anyone 2 years of age and older should wear a mask in all indoor public places, regardless of their immunization status.
“While the county does not require masking at private gatherings where unvaccinated or immunocompromised people are present, universal masking in these scenarios, especially indoors, is the best way to protect everyone,” department officials said.
