Update on the Omicron Variant in Los Angeles County (as of May 9, 2022):
For the week ending April 16, Omicron accounted for 100% of all positive cases that were sequenced, with the BA.2 lineage and sub-lineages accounting for 96% of these positive sequenced specimens in Los Angeles County. For the week ending April 30, the CDC estimates that BA.2 accounted for 62% of sequenced specimens and BA.2.12.1 accounted for 37% of positive sequenced samples in the U.S.
The CDC estimates that BA.2.12.1 may be 25% more transmissible than BA.2. In Los Angeles County, for the week ending April 16, 8% of positive sequenced specimens were identified as BA.2.12.1.
With these highly infectious subvariants and sub-lineages in circulation, cases are increasing in the County. The average number of daily new cases reported over the last seven days increased to 2,532 compared to the 905 reported one month ago, an increase of 180%.
To date, the increases in case numbers have not translated to increases in severe illness, with hospitalizations and deaths remaining low and decreasing. Over the last seven days, the average number of hospitalized cases per day was 245, similar to hospitalization numbers one month ago. Deaths decreased to an average of four daily deaths a day this past week, a 72% decrease from one month ago when the average number of daily reported deaths over the previous seven days was 14.
The lower numbers of hospitalizations and deaths reflect, in large part, the protection provided by the vaccines against the variants. For the week ending April 22, unvaccinated people were four times more likely to be hospitalized compared to residents who were fully vaccinated, but not boosted, and five times more likely to be hospitalized than those fully vaccinated and boosted. And the likelihood of dying was also five times higher for unvaccinated residents compared to residents who were fully vaccinated, but not boosted, and 12 times higher compared to residents who were fully vaccinated and boosted for the week ending April 15.
Los Angeles County Department of Public Health Continues to Require Masks in All Public Transit and Indoor Transportation Hubs Within Los Angeles County
The Los Angeles County Department of Public Health issued a revised Health Officer Order to note that masking in all public transit within Los Angeles County and in Los Angeles County indoor transportation hubs continues to be required.
Per the revised Order, masking continues to be required to be worn by everyone, 2 years of age and older, regardless of their COVID-19 vaccination status, on public transit within the County. This includes wearing masks on commuter trains, subways, buses, taxis and ride-shares. Masking continues to be also required in indoor transportation hubs including airport and bus terminals, train and subway stations, seaport or other indoor port terminals, or any other indoor area that serves as a transportation hub.
The Los Angeles County Department of Public Health will reassess the indoor masking requirement when COVID-19 community transmission in Los Angeles County drops to the Moderate level, OR the CDC’s assessment is that an order requiring masking in the transportation corridor is no longer necessary for protection of the public’s health, OR within 30 days of this Order, whichever occurs first.
