San Diego County health authorities have confirmed the deaths of two young children linked to influenza as the region experiences an unusually early start to this year's flu season.

The fatalities occurred this month and involved an 11-year-old who had no prior health complications and a 6-month-old infant who had been living with complex medical issues, according to county officials.

The 2026 influenza season has begun sooner than usual in the area, prompting concern among public health experts about the potential severity of the outbreak. Health officials typically track flu activity closely during the fall and winter months, but the early arrival of cases this year has shifted that timeline.

The deaths serve as a reminder of the serious risks influenza poses to vulnerable populations, particularly young children, the elderly, and individuals with underlying health conditions.
