California is experiencing a rise in flu cases and hospitalizations, as public health officials confirm a second pediatric death related to the influenza virus for the current season. According to the Centers for Disease Control and Prevention (CDC), there have been a total of 17 pediatric deaths nationwide due to the flu this season.
The CDC has indicated that flu activity is expected to remain elevated across the United States for several weeks. In California, the state’s Department of Public Health has detected a strain known as H3N2 subclade K, often referred to as a “super flu.” This strain is believed to be contributing to the increased seasonal flu activity in the state, prompting public health officials to encourage vaccinations against the virus.
Data indicates that flu positivity rates in Southern California, particularly in Los Angeles, began to rise in December, with mid-January data showing moderate positivity rates. This figure, while concerning, is still lower compared to levels from the previous year at the same time. The World Health Organization has also stated that current data does not suggest an increase in the severity of the circulating flu variant.
Health experts have debated the term “super flu,” with some asserting that it lacks medical significance. Regarding other respiratory viruses, the CDC reports that COVID-19 activity in California remains very low, with positivity rates in Southern California classified as very low. In contrast, respiratory syncytial virus (RSV) positivity rates have been moderate but show a slight increase compared to the previous week.
Additionally, reports from San Bernardino County highlight a surge in whooping cough cases compared to last year, presenting another public health challenge.
Understanding the transmission of the flu is crucial, as individuals can spread the virus a day before symptoms appear and remain contagious for up to a week after becoming ill. Many are finding it difficult to distinguish between flu and COVID-19 symptoms, as both illnesses can present similar respiratory symptoms. Testing remains essential for accurate diagnosis.
As health officials urge vaccinations and monitoring of symptoms, individuals are encouraged to remain vigilant, especially during this flu season marked by increased activity and hospitalizations.
