Dengue spread neither unusual nor alarming this year: Tamil Nadu Directorate of Public Health

The Directorate of Public Health in Tamil Nadu has reassured the public that the spread of dengue this year is neither unusual nor alarming, dispelling any concerns of a significant rise in cases. The DPH stated that seasonal variations in dengue cases are common during the monsoon due to fluctuating climatic conditions. Comparing official data from January to September over the past three years, the authorities found that the current situation aligns with historical patterns.

In 2024, 34,339 people were affected by dengue, with 13 deaths reported. The following year, 2025, saw 15,688 affected individuals and 13 fatalities. As of September 16, 2026, 16,334 cases have been reported, with nine deaths. This year's dengue cases are similar to those in 2024, according to the National Centre for Vector Borne Diseases Control.

The DPH emphasized that mosquito breeding typically increases during the monsoon, particularly from October to December, and that continuous monitoring and intensified preventive measures are being implemented. They deployed officers across the state to coordinate dengue prevention and control, established fever wards for timely treatment, and conducted triage to prioritize patient care based on illness severity.

The department urged the public to actively participate in dengue prevention by eliminating mosquito breeding sources in and around their homes, such as stagnant water in unused containers, plastic items, coconut shells, and old tires. They were also asked to cooperate with government and local body efforts in mosquito control and dengue prevention.

If fever symptoms occur, individuals are advised to seek medical advice from the nearest primary health center or government hospital promptly. The DPH highlighted that effective dengue transmission control relies on public cooperation for preventive measures.
