Decades of data reveal who's most at risk of snakebites and how to prevent them
Snakebites aren't random but are predictably correlated with a variety of environmental and socioeconomic factors, according to a study published Aug. 6, 2026, in the journal PLOS Neglected Tropical Diseases by Jaideep Menon of Amrita University, India, and colleagues.
A scoping systematic review of 142 studies, encompassing over 200,000 snakebite incidents dating back to the 1800s, has identified environmental and socioeconomic factors that correlate with snakebite occurrences. Published in PLOS Neglected Tropical Diseases on August 6, 2026, the study reveals that snakebites are not random events but are strongly linked to occupation, timing, and poverty-related factors.
The analysis, led by Jaideep Menon from Amrita University in India, found that nearly 70% of snakebite cases take place during outdoor work, particularly in farming and construction. Timing also plays a crucial role, with the majority of incidents occurring during rainy seasons and in the evening or early night hours. Poverty-related factors, such as inadequate footwear, poorly secured homes, and limited access to health education, further exacerbate the risk.
These findings highlight areas where targeted policies could significantly reduce the incidence of snakebites. The authors emphasize that efforts should extend beyond antivenom distribution to include workplace safety measures, rural development initiatives, improvements in housing conditions, and comprehensive health education programs.
They caution that the existing dataset, primarily focused on South Asia, is limited due to inconsistent reporting of variables involved in each snakebite incident. Future research is needed to fill these gaps and achieve a more comprehensive understanding of the global factors contributing to snakebite prevalence.
The authors assert that the "inverse care law" is particularly relevant to snakebite, noting that individuals most exposed to snakes—due to their geographical location and occupation—are also the least likely to have access to medical facilities capable of treating snakebites. They conclude that antivenom, while essential, is insufficient on its own as a solution. Instead, prevention strategies must address the underlying behavioral and environmental factors that place individuals at risk in the first place.
