A look at the weekly trends in Los Angeles infections and inoculations

As COVID-19 continues to pose a threat, tactics are increasingly shifting to vaccine mandates and proof of protection. On Sept. 20, the state began requiring vaccine verification or a recent negative COVID-19 test for all attendees of indoor mega-events—defined as those that attract more than 1,000 people, and encompassing everything from sporting events to concerts to conventions. Self-attestation will no longer be an option. Crosstown is following the progress on all coronavirus information to deliver the most important data about infections and vaccinations.


Shot attempts

Weekly vaccination rates are now sitting in the low 100,000s, and the week-to-week increase of the percentage of people fully protected is rising at a snail’s pace, a further sign that there remain a number of hard-to-vax Angelenos. From Sept. 10-16, 116,499 total doses were administered in the county, including 66,585 second doses, according to the Los Angeles County Department of Public Health. One week prior, nearly 115,000 vaccinations were put into arms within a seven-day period.


As of Sept. 16 (the most recent day for which data is available), 12,106,204 doses had been administered in Los Angeles County. A total of 5,432,889 second doses had been dispensed to county residents.

This breaks down to 76.3% of residents 12 and older having received at least one dose, and 68% are fully vaccinated. The figures continue to climb for seniors, as 91% of the 65-plus crowd has received at least one shot, and 82% are fully vaccinated.


Despite overall vaccinations increasing, there continues to be a disparity in coverage among different ethnicities. As of Sept. 16, 80.4% of Asian residents over the age of 12 in L.A. County had received at least one dose, making them the group with the most cumulative protection. About 70.7% of white residents had been vaccinated.


Meanwhile, the Latinx and Black populations have far lower community vaccination rates. According to the Department of Public Health, 61.2% of Latinx Angelenos had received at least one dose, and 52.5% of Black residents had taken one shot.

These figures show that not much progress has been made from a racial divide that existed months ago. On May 2, the County reported that only 36.5% of Black residents had received at least one shot, compared with 66% of Asian residents, 59.1% of white Angelenos and 40.2% of Latinx people.


Case count

The average COVID-19 case rate continues to be on a downward trend. From Sept. 7-21, average cases dropped by 21%. In the previous two-week period, average cases fell by 34.8%. On Tuesday, the seven-day average was 1,637. This is the lowest case average since July 20. 


Daily hospitalizations are also ticking downward. On Wednesday, 1,018 county residents were hospitalized with COVID-19, according to the Department of Public Health. This is a more-than 40% drop from the 1,724 people being treated in hospitals about four weeks prior.

On Monday, the daily positivity rate was 1.2%; this is the lowest figure since July 1. On Wednesday, the level stood at 1.7%. The recent high point was the 6.6% positivity on Aug. 3.
