Flu surges in California while vaccination rates dip

As California battles its worst flu season in five years, health officials are alarmed by declining vaccination rates, especially among children, leaving thousands vulnerable to severe infections.

Key Takeaways:

  • California is experiencing its worst flu season in five years.
  • Flu positivity rates at state labs have reached nearly 28%.
  • Vaccination rates among children have dipped to a record low since at least 2019-20.
  • At least 10 unvaccinated children have died from the flu in California this season.
  • Health officials urge the public to get vaccinated as the flu season shows signs of lingering.

California’s Flu Surge Reaches Unprecedented Levels

California is grappling with its worst flu season in five years, as infections and hospitalizations spike while vaccination rates decline. The classic flu virus is overwhelming the state this winter, even as COVID-19 cases decline and concerns about bird flu simmer.

Positivity Rates Near 28%

The positivity rate for flu tests at state labs soared to nearly 28% as of February 1, a level not seen since the onset of the COVID-19 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,” reported Rong-Gon Lin II of the Los Angeles Times.

According to the Centers for Disease Control and Prevention, flu levels in California’s wastewater are categorized as “very high.” In contrast, RSV levels are “high,” and COVID-19 levels are considered low. While positive test rates for RSV and COVID-19 are falling nationally, they continue to rise for the flu.

Declining Vaccination Rates Among Children

A significant factor contributing to the surge is the declining rate of flu vaccinations, particularly among children. Only 47.7% of California’s children have been vaccinated against the flu as of late January—the lowest rate since at least the 2019-20 flu season. Last year at this time, the vaccination rate was 53.7%.

“Fewer children have gotten a flu shot this season, leaving thousands more vulnerable to severe infections as cases surge,” Lin noted. Health officials are concerned that low vaccination rates are exacerbating the spread and impact of the virus.

Tragic Impact on Young Lives

The flu has had a devastating impact on children in the state. At least 10 children have died from the flu in California this season, including three teenagers in San Diego County. None of these young victims were vaccinated.

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

Schools have become hotspots for infections, with some campuses in other states closing this season due to flu outbreaks. The rise in cases among unvaccinated children underscores the critical need for increased vaccination efforts.

National Perspective on the Flu Season

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

“Influenza predictions suggest that emergency department visits will remain high and may increase in most states,” CDC officials stated. The widespread nature of this flu season highlights the importance of proactive measures to curb its impact.

Urgent Calls for Vaccination

Health officials are adamant that vaccination is the most effective tool to combat the flu’s spread. They advise people to get a flu shot if they haven’t already, especially since this flu season is more likely to linger.

“Health officials point to one essential step to limit the spread of infection: get vaccinated if you haven’t already,” Lin emphasized. The urgency is compounded by concerns over growing skepticism surrounding vaccine safety.

Concerns Over Vaccine Skepticism

Some health experts are alarmed by the rise in skepticism regarding vaccine safety. “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,” Lin reported.

This skepticism may be contributing to lower vaccination rates, further complicating efforts to control the flu outbreak.

A Critical Moment for Public Health

As the flu continues to pummel California, the convergence of high infection rates and low vaccination uptake presents a significant public health challenge. Health officials urge immediate action to prevent more illnesses and deaths.

The message is clear: Vaccination remains the most effective defense against the flu. With the season far from over, there is still time to increase immunity and protect communities across the state.
