Snakebite in India: Unveiling the Madras Crocodile Bank's Lifesaving Project
"Learn about the Madras Crocodile Bank's mission to mitigate snakebites in India through research, education, and antivenom accessibility."
Snakebite is a silent crisis in rural India, where numerous venomous snake species thrive in agricultural zones, creating frequent encounters with humans. Among the most dangerous are the 'Big Four': the spectacled cobra, Russell's viper, common krait, and saw-scaled viper. Bites from these snakes lead to significant morbidity and mortality.
While a polyvalent antivenom exists to treat these bites, its availability and public awareness remain insufficient. This gap in access and knowledge contributes to the high death toll from snakebites each year.
The Madras Crocodile Bank/Centre for Herpetology (MCB), along with its partners, is actively addressing this issue through a comprehensive snakebite mitigation project. Their work includes venom sampling and research, mapping snakebite treatment centers, and conducting nationwide awareness campaigns.
Measuring India’s Snakebite Burden
India’s snakebite response includes the National Programme for Prevention and Control of Snakebite Envenoming, whose vision is to reduce snakebite deaths until vulnerable populations are free from the fear and impact of snakebite-related events. The WHO Snakebite Data Information Portal supports prevention and control worldwide and is designed to improve access to relevant data and resources. WHO also requests endemic countries to report annual snakebite cases and associated deaths with sub-national detail, while an analysis of India’s Million Death Study examined 2,833 snakebite deaths identified through 611,483 verbal autopsies.
India's Snakebite Crisis: A Neglected Health Emergency
With an estimated 46,000 deaths annually, snakebite is a major public health issue in India. Herpetologists recognize the urgent need for action, driven by growing awareness among young naturalists who are eager to contribute to solutions.
- Education and Awareness: Rural outreach services target schools and community venues in the most affected Indian states.
- Venom Sampling: Collaboration with the Gerry Martin Project and the Evolutionary Venomics Laboratory of the Indian Institute of Science aims to characterize venoms and test the efficacy of Indian antivenoms.
- Mapping Snake Occurrences: Partnering with IndianSnakes.com to map the distribution of medically important snake species.
- Identifying Treatment Centers: Locating clinics that stock antivenom and clinicians experienced in treating snakebites, ensuring 24/7 availability.
Research and National Planning
India’s National Action Plan for Snakebite Envenoming provides a broad framework for managing, preventing, and controlling snakebite envenoming. A 2025 narrative review examines the Madras Crocodile Bank Trust’s grassroots work through education, advocacy, research, and venom production. Other recent research has analyzed clinical and demographic profiles at AIIMS Rishikesh from July 2021 to July 2023 and explored current practices, challenges, and opportunities for improving snakebite management across India.
Persistent Gaps in Protection
The Madras Crocodile Bank Trust review reports difficulties with knowledge retention, behavioral change, and funding, indicating that prevention and awareness efforts require sustainable, integrated grassroots investment. WHO notes that many people either lack access to antivenom or cannot afford it. Research has also identified a lack of Indian studies quantifying snakebite morbidity through Disability Adjusted Life Years, while the effectiveness of antivenoms against neglected Indian snake species still requires further preclinical and clinical validation.
Training Through Partnership
The Madras Crocodile Bank Trust and the Centre for Environment Education conducted a teacher training workshop on snakebite mitigation and first aid on 22 November 2017. The workshop was attended by 256 teachers. This example shows how snakebite education can be delivered through collaboration with educators rather than relying only on clinical services.
A Call to Action: Joining the Fight Against Snakebite
Students, doctors, and wildlife activists are encouraged to connect with the Madras Crocodile Bank's snakebite mitigation project. The serious work is really only just beginning, and with the World Health Organization designating snakebite as an A-list Neglected Tropical Disease in 2017, we are optimistic that the time has come for both the Government of India and private players to finally tackle and solve this deadly problem affecting India's farmers. As India's chapter of the Global Snakebite Initiative we are building up local partnerships, collaborating with national and international experts in the fields of herpetology, venomology, health and social science, and, of course, are always on the look out for donor agencies to support the work being done, even in the most remote parts of the country.
Evidence, Policy, and Local Risk
A protocol for synthesizing evidence on snakebite risk factors in India proposes analyzing each risk-factor and outcome pair separately and using a random-effects model with 95% confidence intervals according to JBI guidelines. A recent commentary reports that India’s snakebite deaths exceed 46,000 annually and that compensation and response remain state-specific. It also argues that climate change is shifting venomous snake ranges, creating unequal relief challenges for affected families.
Climate-Driven Risk Shifts
A PLOS Neglected Tropical Diseases study titled “Future of snakebite risk in India: Consequence of Climate Change and the Shifting Habitats of the Big Four Species in Next Five Decades” examines how climate change may alter snakebite risk. Its author summary identifies snake envenomation as a critical public health issue that disproportionately affects economically deprived populations. The study and related reporting focus on the possibility of new snakebite hotspots as the habitats of India’s Big Four species shift.
Regional Clinical Complexity
Snakebite envenoming remains a significant public health challenge in India, particularly in rural areas where timely and appropriate medical care is limited. Management is complicated by the region’s diverse venomous snake species, whose venoms can produce different effects in the human body. The source also notes that these challenges persist despite advances in antivenom production.
A Global Emergency With Local Costs
WHO estimates that 5.4 million people worldwide are bitten by snakes each year, including 1.8 to 2.7 million cases of envenoming. The organization estimates that snakebites cause approximately 81,410 to 137,880 deaths annually. Around three times as many amputations and other permanent disabilities are caused by snakebites each year, underscoring the wider human impact beyond mortality.
