L.A. City and County COVID-19 Weekly Update (April 26, 2021)

CA Health and Government COVID-19 Guidance: Week in Review

Overall Downward Trends Continue in L.A. County

The County continued to experience declines in COVID-19 cases, with new cases down 98% from the peak of the surge, deaths down 97% and hospitalizations down 94%. As of April 20, 2021, the County’s adjusted case rate was 2.7 new cases per 100,000 people, down from 3.2 the previous week. The test positivity rate also fell from 1.5% to 1.2%, and in areas with the fewest health-affirming resources, the County’s test positivity rate dropped from 1.9% to 1.4%. The County’s adjusted case rate will need to fall to 2 cases per 100,000 residents in order for the County to be eligible to move up from Tier 3 to Tier 4 status under the State’s Blueprint, which would further reduce state restrictions on economic activity in the County.​

Finally, the County’s estimated transmission number is now 0.86, down slightly from the previous week’s estimate of 0.90. The model suggests that approximately 0.06% of County residents, or 1 in 1,600, are currently infected and infectious to others. One week earlier, this estimate was 1 in 1,400.



As of April 23, 2021, the County reported administering more than 6.6 million doses of vaccine in the County, including 4,254,160 first doses, 2,387,785 second doses, and 274,212 doses of the single-dose Johnson & Johnson vaccine. (The FDA-ordered brief pause in use of the J&J vaccine was lifted on Friday, April 23, 2021.) The County also launched a vaccine tracker for real-time updates on vaccination rates, including interactive data tools.

This week, the L.A. County Department of Public Health expects to receive approximately 296,000 vaccine doses, an 18% decrease from last week. Approximately 51% of this week’s vaccine supply will be for first doses and 49% will be for second doses. Of the 296,000 doses of vaccine the County expects to receive this week, 75% of doses will go to sites located in the most vulnerable communities. The County is also resuming the use of the Johnson & Johnson vaccine.

As of April 20, “75% of L.A. County residents 65 and older have received at least one dose and 60% of residents 65 and older have been fully vaccinated. Overall, 48% of L.A. County residents 16 and older have received at least one dose of vaccine and 30% have been fully vaccinated.”
