Good morning. Here’s what you need to know to start your day.

California’s worst flu season in 5 years

Bird flu is being felt in the egg aisle and COVID-19 is still with us — but seasonal influenza is the virus pummeling California and the rest of the U.S. this winter.

The classic flu is surging in the Golden State, with infections and hospitalizations rising at the same time vaccination rates have dipped.

The positivity rate for flu tests at state labs was nearly 28% as of Feb. 1, marking a level not seen since the start of the pandemic in early 2020.

“That’s higher than the peak of the ‘tripledemic’ winter of 2022-23, when California’s hospitals were stressed by simultaneous high circulation of flu, COVID and respiratory syncytial virus, or RSV,” Times reporter Rong-Gon Lin II wrote this week.

Flu is up, COVID is down

According to the Centers for Disease Control and Prevention, the levels of flu in California’s wastewater are “very high.” For comparison, respiratory syncytial virus (RSV) levels are categorized as “high” and COVID levels are considered low. Positive test rates are falling nationally for RSV and COVID, but continue to tick up for flu.

“Influenza predictions suggest that emergency department visits will remain high and may increase in most states,” CDC officials said last week.

Nationally, the CDC estimates there have been roughly 13,000 flu deaths so far this season, including 57 children. At least 24 million illnesses and 310,000 hospitalizations have been recorded.

“This has been a particularly long and difficult flu season compared to recent years,” Dr. Ankita Kadakia, interim public health officer for San Diego County, told Ron. “And it’s not over yet.”

One major complication this season: Fewer children have gotten a flu shot

That’s leaving thousands more vulnerable to severe infections as cases surge.

“47.7% of California’s children have been vaccinated against flu as of late January … the lowest since at least the 2019-20 flu season,” Ron noted. “Last year at this time, 53.7% of children were vaccinated against flu.”

At least 10 children have died from the flu in California this season, including three teenagers in San Diego County. None of those young victims were vaccinated, Ron reported.

Schools can quickly become hot zones for infections. Some campuses in other states have closed this season due to flu outbreaks.

Health officials point to one essential step to limit the spread of infection: get vaccinated if you haven’t already, especially since this flu season is more likely to linger.

That’s advice we may start getting less often — at least from the federal government.

“Some health experts have expressed alarm about the rise in skepticism surrounding vaccine safety — including from Robert F. Kennedy Jr., President Trump’s nominee to run the U.S. Department of Health and Human Services,” Ron noted.

President Trump has declared the last straw

  • He’s also tasking the executive branch with developing a “National Strategy to End the Use of Paper Straws” by March 27.

After this Australian town burned down, experts warned against rebuilding. Nobody listened. The Australian town of Marysville once faced the same questions being asked in the Los Angeles neighborhoods that burned. It has been rebuilt to be much safer, but some fire experts say that Marysville will almost certainly burn again. “They shouldn’t have built it back,” said Greg Mullins, a former fire commissioner for the neighboring state of New South Wales. “No question.”
