Snakebite envenoming or poisoning remains a major but often overlooked public health problem in rural India. It not only claims lives but also leaves many survivors with long-term health issues and financial hardship. A pioneering study by a team of scientists on the economic burden of snakebites has revealed alarmingly high levels of long-term illness among survivors.

The is due to the delays in receiving appropriate treatment, lack of awareness, and, in many cases, ineffective care. While mortality may appear relatively lower either due to improved access to healthcare or under-reporting linked to social taboos, the findings reveal that nearly one in four victims suffers lasting health complications.

The community-based retrospective study, conducted in Jagtial district of Telangana by researchers from the Hyderabad-based CSIR-Centre for Cellular and Molecular Biology (CCMB), highlights the deep and lasting impact of snakebites on agrarian households.

Based on interviews with 541 individuals across 205 villages between 2010 and 2020, the study found that 24.21% of victims developed morbidities, while 12.75% died. This translates to a mortality rate of 11.72 and a morbidity rate of 22.8 per one lakh population. Nearly 32 Disability-Adjusted Life Years (DALYs) , a measure where one DALY equals one lost year of healthy life, are lost per 1,00,000 people annually, underscoring the scale of the crisis.

The economic burden is equally severe. The average annual loss in income due to reduced earning capacity is estimated at ₹26,528.60 per person while mortality-related losses exceed ₹19.83 lakh per individual. These figures reflect not just lost wages, but also the destabilising impact on families dependent on working-age adults, particularly men engaged in farming, said CCMB-LaCONES chief scientist Karthikeyan Vasudevan. 

Even survivors continue to bear the cost. Many reported long-term physical disabilities, along with psychological effects such as fear, anxiety and insomnia factors not fully captured in economic estimates. The true burden of snakebites is likely much higher than what we have documented, noted Mr. Vasudevan.

The study found that most victims were farm workers aged 15 to 59, exposed during routine agricultural activities such as harvesting, irrigation, and manual handling of crops often barefoot or without protective gear. Most bites occurred on the lower limbs, either in fields or around homes where snakes seek shelter.

Despite free treatment availability in government hospitals, over 80% of victims sought care in private facilities, incurring high out-of-pocket expenses. Treatment costs varied widely, ranging from negligible amounts to as high as 7 lakh, pushing many households into financial distress.

Delayed access to proper treatment remains a critical concern, often caused by long distances to hospitals, lack of transport, and reliance on traditional or faith healers. The study notes that such healers continue to play a significant role in rural healthcare-seeking behaviour. Researchers suggest integrating them into formal reporting systems and encouraging them to refer patients to hospitals promptly.

The study also highlights that residents of traditional housing are more vulnerable, and a significant number of victims were unable to identify the snake involved. Among those identified, the Indian cobra (Naja naja) and Russell’s viper (Daboia russelli) were the most common, followed by the common krait and saw-scaled viper.

Most bites occurred on the feet and during daytime hours, especially between noon and 7 p.m., often correlating with specific snake species activity patterns. Calling for urgent action, scientists recommend targeted measures such as improved ambulance services and community-level awareness campaigns, stressing the need for a grassroot village-level approach to documenting and addressing snakebite burden.

Standardised data collection, improved compensation mechanisms, and strengthened rural healthcare systems will be critical in reducing both the human and economic costs of this neglected public health crisis, the researchers, including Swapnil Kiran and Siripuram Srinivas, added.
