The 2024-2025 respiratory virus season struck a severe blow recently, with the Fresno County Department of Public Health (FCDPH) announcing Tuesday the first deaths associated with influenza (flu) and respiratory syncytial virus (RSV) in young people.

As of March 22, the California Department of Public Health (CDPH) has reported 24 influenza-associated deaths statewide among individuals aged 0-17, as well as 331 deaths in individuals aged 18-64. An additional 1,054 deaths were reported among individuals 65 and older.

The two fatalities in Fresno County were both pediatric cases. No other information was reported about the deaths.

“Our deepest condolences go out to the families and loved ones of these children,” said FCDPH Interim Health Officer Dr. Rais Vohra. “With respiratory infections still circulating in our community, it’s important to remember that it’s not too late to get vaccinated against the flu and, if eligible, against RSV.”

The department urges everyone six months and older to get vaccinated, specifically highlighting the importance for those at high risk for severe illnesses, including adults aged 65 and older; children under 5; pregnant individuals and people suffering from underlying health conditions including asthma, diabetes, heart disease and obesity.

Symptoms of RSV and the flu are commonly similar and include coughing, runny nose, sore throat, fever, nasal congestion and body aches. The department urges individuals experiencing these conditions to remain at home until symptoms have improved to avoid spreading the illness.

Additionally, residents are urged to take precautions following recovery, including ventilation of indoor spaces, maintaining social distancing and wearing well-fitting masks in crowded indoor environments.

Individuals at higher risk are urged to consider flu testing and should reach out to their health care provider about prescription medications for treatment.

The department recommends pregnant individuals receive one RSV dose between 23 and 26 weeks to protect newborns against severe RSV infection. Infants under eight months are recommended to receive one dose of Nirsevibam — which is an antibody against RSV — for initial protection.

Parents are encouraged to seek medical attention for children who are struggling to breathe, drink enough fluids or who experience worsening symptoms.
