Tamil Nadu has reported 263,000 dog bite cases and 17 deaths from rabies in the first four months of 2026, according to data from the Directorate of Public Health and Preventive Medicine. The figures represent nearly 42% of the 625,000 bites and half of the 34 deaths recorded in all of 2025. Cases peaked in March with 71,000 reports, following 62,000 each in January and February, and 68,000 in April.

Chennai, Salem, Tiruchi, and Dindigul are among the districts with the highest incidence. A. Somasundaram, Director of Public Health, confirmed a marginal rise in cases and emphasized that rabies is 100% fatal with no specific treatment, making vaccination the sole preventive measure. Health authorities are focusing on wound washing, timely administration of anti-rabies vaccine, and use of rabies immunoglobulin for high-risk and deep bites.

The state continues to face challenges in scaling up Animal Birth Control (ABC) programs and dog vaccination coverage amid a growing stray dog population. Local bodies and veterinarians are tasked with implementing ABC measures and mass dog vaccination, though coordination gaps persist. The DPH is also conducting defaulter tracing to ensure patients complete their vaccine schedules.

Medical experts, including S. Chandrasekar of Government Stanley Medical College Hospital, urged immediate medical attention for all animal bites, especially among children, who are more vulnerable. Authorities are increasing public outreach to stress that bites from pet dogs also require post-exposure prophylaxis.

The Health Department will expand its monitoring of vaccine compliance and intensify community awareness campaigns in high-burden districts over the coming months.
