Chennai, Jan 8 || Tamil Nadu has reported the highest number of dengue cases in the country in 2025, even as the death toll has remained relatively low due to early detection and prompt medical intervention, according to the latest data released by the Union Health Ministry.
Between January and November 2025, the state recorded 20,866 dengue cases and 12 deaths. Health officials attributed the high case count not to an uncontrolled outbreak, but to the strength of Tamil Nadu’s disease surveillance and reporting system, which tracks infections from the primary health centre (PHC) level to secondary and tertiary care hospitals.
Among the southern states, Kerala reported the highest number of dengue-related deaths, with 49 fatalities and 10,239 cases during the same period.
Andhra Pradesh reported 2,384 cases and five deaths, while Telangana recorded 8,139 cases with no deaths, and Karnataka reported 6,759 cases, also without any fatalities.
