The emergence of a new strain of influenza A, specifically the H3N2 subclade K, has led to increased influenza activity and hospital admissions across California. The California Department of Public Health (CDPH) issued this warning as officials reported a concerning rise in cases statewide. The state has confirmed the second pediatric flu-associated fatality for the current season, underscoring the urgency of vaccination efforts.
State Health Officer Dr. Erica Pan stated that while the new strain circulates globally, current seasonal vaccines continue to provide effective protection against severe illness and hospitalization. “Vaccines, tests, and treatments remain widely available,” she emphasized, encouraging residents to consider getting vaccinated if they have not yet done so. She has also taken steps to protect her own family against the virus.
The CDPH is advising everyone aged six months and older to receive the flu vaccine. Rapid testing is recommended for individuals showing symptoms, particularly those at risk for severe disease. Immediate antiviral treatment is also advised for high-risk patients and those already hospitalized.
Local health professionals are echoing the importance of preventive measures as flu activity rises. Dr. Kenny Banh, a professor of clinical emergency medicine at UCSF Fresno Mobile Health, highlighted the significant benefits of annual influenza vaccinations. He noted that these vaccines not only reduce the likelihood of infection but also lessen the severity and duration of symptoms for those who do contract the virus. This, in turn, can decrease hospitalizations and mortality rates.
To mitigate the risk of flu transmission, Dr. Banh recommends avoiding close contact in poorly ventilated areas, practicing good hand hygiene, and covering the mouth and nose when coughing or sneezing. This can be achieved through mask-wearing or using the elbow to contain respiratory droplets.
The CDPH encourages Californians to schedule flu vaccinations through healthcare providers, local pharmacies, or the state’s online platform at myturn.ca.gov. For further prevention guidance, residents are urged to consult resources from the Centers for Disease Control and Prevention (CDC).
As the flu season continues, public health officials remain vigilant in their efforts to combat the spread of influenza and protect the health of all Californians. The combination of vaccination and adherence to preventive practices is essential in managing this public health challenge effectively.
