South African and Brazilian P.1 Variants Detected in L.A. County

The Los Angeles County Department of Public Health or Public Health has confirmed 53 new deaths and 479 new cases of COVID-19. To date, Public Health identified 1,223,174 positive cases of COVID-19 across all areas of L.A. County and a total of 23,340 deaths.

Public Health has identified one case of the South African variant, B.1.351, and three cases of the Brazilian P.1 variant, both variants of concern. The Centers For Disease Control or CDC classified the South African and Brazilian variants as variants of concern because they are potentially associated with increased transmissibility and reduced susceptibility to certain therapeutics. Although these are the first reported cases of the South African and Brazilian variant in L.A. County, it is likely there are additional undetected/undiagnosed cases. To date, 33 cases of the Brazilian variant and 10 cases of the South African variant have been reported in California.

Among 70 specimens analyzed at the Public Health Laboratory this past week, 64% of the specimens analyzed were the UK variant of concern, B.1.1.7 and 20% were the California variant of concern identified as B.1.427 or 429. This means 84% of the variants identified this past week are variants of concern with the probability of increased transmissibility and more severe disease. Three cases of the New York variant were also detected this week, which is a variant of interest. There were no cases of the Brazilian P.2 variant identified this week.

All key metrics indicate less community transmission; the rate of decrease is slowing for hospitalizations and cases.

During the month of February, the daily number of cases dropped 82% from February 1 to February 28. During the month of March, the daily number of cases continued to decrease, but dropped only 42% from March 1 to March 30. There is a similar slowing for hospitalizations, as well. During the month of February, the number of daily hospitalizations dropped 70% from February 1 to February 28 with only a 57% drop from March 1 to March 30.

The average number of daily deaths continued to decrease in March compared with February. The daily number of deaths dropped 63% from February 1 to February 28. In March, average daily deaths decreased by 86% from March 1 to March 30. This is welcomed news as it indicates we are still seeing declines in the very high number of deaths L.A. County experienced through January and February.

As of March 26, the mortality rate among residents in the lowest resourced areas is down significantly to just 4.5 daily deaths per 100,000 people, but is still three times higher than the mortality rate for people living the highest resourced areas, which has dropped to 1.5 daily deaths per 100,000 people.

From January 2020 to date, 7,011 people experiencing homelessness in Los Angeles County tested positive for COVID-19 and 202 people who were experiencing homelessness passed away from COVID-19. Similar to the overall trend in L.A. County, COVID-19 cases among people experiencing homelessness have declined significantly from the peak of 652 weekly cases during late-December, to fewer than six new cases reported last week. The number of deaths per week from COVID-19 among people experiencing homelessness peaked at 19 deaths in late December and have declined significantly to 1 death last week.  

Since February 2021, dozens of providers across the county have administered 11,483 COVID-19 vaccine doses to people experiencing homelessness. To lower barriers to vaccination, the county is employing both traditional clinic-based vaccination models and heavily relying on mobile teams to bring vaccines to people experiencing homelessness where they are, including shelters, encampments, churches and access centers. 

Public Health remains committed to increasing the number of vaccination sites in the hardest hit communities in L.A. County. Similar to efforts for vaccinating people in hard hit communities, the county deploys mobile vaccination teams to congregate senior housing facilities where many homebound individuals live. The county is partnering with programs such as Meals on Wheels and other community based organizations and others, including the county’s Sheriff Department which is a critical partner in this effort. To date, 15 local fire departments have partnered with us to vaccinate homebound residents, and we expect more in the coming weeks.

While gaps in vaccination rates persist by race and ethnicity for residents 65 and older, since February, Black residents 65 and older have seen the largest increase in vaccination rates at 145%. The County is also seeing large increases in the vaccination rate for Latinx residents, which increased by 114% from February 9 to April 2. Over this time period, the rate for American Indian/Alaska Native increased by nearly 110%. These increases translate into more protection for all with just about 50% or more of people 65 and older vaccinated across each race/ethnic group. 

COVID-19 vaccine eligibility expanded to all residents 50 through 64 years old in addition to all other eligible groups. On April 15, vaccines become available to any resident in Los Angeles County who is 16 and older.For information about who is eligible for COVID-19 vaccine in L.A.
