Region-Specific Antivenoms
Snakebite envenoming remains a critical health challenge in India, especially in regions where the standard polyvalent antivenom is less effective. Recent calls from herpetologists and health experts emphasise the urgent need for region-specific antivenoms. This is particularly important in Northeastern India, where snake species differ from the ‘Big Four’ responsible for most deaths nationally. Efforts are underway to establish specialised facilities and improve treatment outcomes.
Current Snakebite Treatment Challenges
India’s standard antivenom is made from venom of four snakes – Indian cobra, common krait, Russell’s viper, and saw-scaled viper. This serum works well in many parts of India but is less effective in the northeast. Here, snakes like monocled cobra, green pit vipers, and other kraits cause most bites. Using the wrong antivenom delays recovery and increases fatalities. There is no widespread supply of region-specific antivenoms to address this gap.
Need for Regional Venom Centres and Serpentariums
Experts suggest creating a Regional Venom Centre to collect venom from local snake species. This centre would support development of antivenoms tailored to regional snake populations. A serpentarium would house live snakes ethically for research and venom extraction. Such facilities help study venom composition and clinical effects specific to local snakes. This approach aims to improve treatment success and reduce complications.
Snakebite Burden and Epidemiology in India
Studies estimate about 58,000 annual snakebite deaths in India, with many more survivors suffering disabilities. Most deaths occur in rural homes and affect working-age adults and children. Eight states bear the highest burden, including Bihar, Jharkhand, Madhya Pradesh, and Odisha. Deaths peak during the rainy season and at low altitudes. Many victims rely on traditional healers and face delays in reaching medical care.
Public Health Response and Awareness
India launched a National Action Plan in 2024 to cut snakebite deaths by half by 2030. Despite this, gaps remain in awareness, infrastructure, and trained personnel. Rural areas lack timely access to quality antivenoms and healthcare. Experts recommend community education, improved first-aid training, and strengthened rural health systems. Collaboration among forest, health, and biodiversity departments is vital.
Mitigation Strategies
To reduce human-snake conflicts, Assam plans a State-Level Steering Committee and a serpentarium for research. A digital platform or app is proposed to report snake encounters and bites. This tool would provide real-time data to guide rescue operations and public health responses. Integration with hospitals and wildlife departments could streamline treatment and conservation efforts.
