Dengue cases in Tamil Nadu decline for third consecutive year as per government data

Dengue cases in Tamil Nadu have continued their downward trend for the third year in a row, according to government data. The State Health and Family Welfare Department reported 17,049 cases up to September 19, 2026, a significant drop from 25,585 cases in 2025, 46,971 cases in 2024, and 56,863 cases in 2023. While the 2026 figure only covers the period up to September 19 and cannot be directly compared to the full-year figures of previous years, the year-on-year decline in reported cases and deaths provides insight into the State's dengue burden.
