Officials alarmed as BA.2 cases rise in Los Angeles County

LOS ANGELES -- The percentage of omicron subvariant BA.2 cases is rising in Los Angeles County, a trend seen elsewhere nationwide as officials sound the alarm about Congress' failure to provide critical funding for vaccinations, tests and anti-coronavirus drugs.

Officials in Los Angeles County and nationally have warned about the risk to public health if new federal funding for the pandemic fails to be approved. There is no money left to reimburse doctors for covid-19 care for uninsured Americans, and funds will soon run out to provide vaccinations, Xavier Becerra, the U.S. secretary of Health and Human Services, said last week.

According to data released Thursday, 14.7% of coronavirus samples analyzed for Los Angeles County between Feb. 27 to March 5 were the highly contagious BA.2 subvariant. That's more than double the previous week's figure of 6.4%.

Los Angeles County Public Health Director Barbara Ferrer continued to urge residents to adhere to the strong recommendation issued by her department and state health officials to continue masking in indoor public settings.

"Along with the increasing circulation of the more-infectious BA.2 subvariant, everyone, especially those who are at elevated risk or live with someone at elevated risk, should wear a high-quality mask and get vaccinated and boosted," Ferrer said in a statement Thursday.

More recent national estimates have suggested BA.2 will quickly become dominant soon. BA.2 comprised an estimated 35% of analyzed samples between March 13 and March 19; the previous week, it made up 22%, according to the U.S. Centers for Disease Control and Prevention.

In the Southwestern U.S. -- which includes California, Arizona, Nevada and Hawaii -- BA.2 made up an estimated 41% of coronavirus samples. The previous week, it was 28%. And for the first time, BA.2 is the now estimated to be the dominant subvariant in the Northeast, making up more than half the analyzed coronavirus cases in New York, New Jersey and New England.

BA.2 is believed to be 30% to 60% more contagious than the earlier omicron subvariant. BA.2, however, doesn't appear to result in more severe illness, and it's likely that people recently infected with the earlier omicron subvariant will have a decent degree of at least short-term immunity to BA.2.

It's not clear whether the rise of BA.2 will result in a major surge that will strain hospitals yet again, or whether BA.2 will merely slow the continued decline in new coronavirus cases. But officials say it's prudent to be prepared for the worst, wear masks in indoor public spaces and get up-to-date on vaccinations and booster shots.

One potential warning sign is from Britain, which has seen its coronavirus case rate more than triple since late February and is reporting more than 1,100 cases a week for every 100,000 residents, according to Johns Hopkins University. Coronavirus-positive hospitalizations are also up by 20% in Britain over a weeklong period, and deaths are on an upward trend as well, according to Britain's coronavirus data tracking website.

In the U.S., the Northeast is likely to provide some hints as to how BA.2 might influence pandemic trends in California.

"Over the past week, we have seen a small increase in reported covid-19 cases in New York state and New York City, and some increases in people in the hospital with covid-19 in New England, specifically, where the BA.2 variant has been reaching levels above 50%," CDC Director Dr. Rochelle Walensky said Wednesday.

"This small increase in cases in the Northeast is something that we are closely watching as we look for any indication of an increase in severe disease from covid-19 and track whether it represents any strain on our hospitals. We have not yet seen this so far," Walensky said.

Cases are relatively flat nationwide and in California. In Los Angeles County, coronavirus cases are still continuing to decline, when accounting for a backlog of cases recently reported that actually occurred earlier in the pandemic.

Officials in Los Angeles County and at the White House have voiced concerns about Congress' failure to provide additional federal funding to respond to the pandemic.

Ferrer said that because of the stalemate in Washington, many of Los Angeles County's community groups were no longer expected to be reimbursed for the vaccination or testing of uninsured people, a situation that "wrecks our network immediately."

"We need to be prepared for a potential challenge in the future -- and in the near future. We don't want to be caught off guard," Ferrer said.

Added Dr. Sara Cody, the public health director for Santa Clara County, Northern California's most populous county: "Covid funding has essentially collapsed. That is breathtaking and shocking in the middle of a global pandemic."

Becerra said Wednesday that there's no money left in the fund Congress created to reimburse doctors for covid care to Americans, particularly the uninsured. The fund will also need to stop accepting new claims for vaccination services around April 5 -- less than two weeks away.

In addition, the federal government now must scale back plans to buy more doses of Evusheld, a drug intended to prevent covid-19 among people who haven't been exposed to the coronavirus, and either have a weakened immune system because of a medical condition or cannot get vaccinated for medical reasons. "This increases the risk of having an insufficient supply of this treatment by the fall," Becerra said.

Without additional funds, the U.S. also risks losing its domestic testing manufacturing capacity. "And because it takes months to ramp back up to rebuild capacity, failure to invest now will leave us with insufficient testing capacity and supply if we see another surge in cases and demand for testing increases once again. That should not be allowed to happen," Jeff Zients, the White House covid-19 task force coordinator, said.

"These consequences will only get more significant over time, with less treatments, vaccines, and tests for the American people," Zients added.
