Summer in the Bay Area means outdoor parties, weddings and music festivals, where people can worry a little bit less about catching COVID-19. But will fast-spreading offshoots of the omicron coronavirus variant change the equation this year?
The highly infectious and immune-evasive BA.4 and BA.5 sub-lineages of omicron are now the dominant strains in Northern California, according to data published by the Centers for Disease Control and Prevention. COVID infections are up across the state as the test-positivity rate nears record levels, meaning the risk is higher in nearly all settings.
Experts say the surge is being driven by the Omicron subvariant known as BA.5, which has rapidly become dominant in the United States and is especially good at infecting people even if they’ve been vaccinated, boosted and already had the virus.
“It’s highly immune-evasive, and that is why it’s causing trouble,” said Dr. Eric Topol, a professor of molecular medicine at Scripps Research in San Diego. “And it comes along in California at the same time that we basically have this delusion that the pandemic is over.”
The entire Bay Area is at the high community risk level for COVID- 19 at which federal regulators recommend everyone wear face masks indoors as newer and more immunity-evasive versions of the omicron variant continue to spread across the country.
While infections remain well below the January peak driven by the initial omicron strains, they’re still at February’s elevated levels and show no signs of declining, Bay Area health officials said Tuesday.
“The pattern we’re seeing in our data does make me think a sustained surge is possible,” Santa Clara County Health Officer Dr. Sara Cody said. “Previous patterns were we went up and then down, but we went up and now we’re staying at a high plateau.” Continue reading Bay Area COVID cases are sky-high→
San Francisco County has the highest COVID-19 case rate of any other county in California with a seven-day average of 13 cases per 100,000 residents, state data showed on Tuesday. By comparison, Los Angeles is reporting 5 cases per 100,000 residents. And San Francisco isn’t the only Bay Area spot sitting at the top of the list. All counties in the region except Solano have among the highest rates in the state.
But multiple experts say this news isn’t alarming, and does not warrant any policy changes. Despite the region’s ranking, cases are extremely low compared to what they were amid the winter surge when the city’s seven-day average soared above 250 cases per 100,000 at the peak.
