Summary: Snakebites are an environmental and occupational health hazard, mainly affecting rural populations worldwide. The ectothermic nature of snakes raises the issue of how climate change impacts on snake ecology could influence the incidence of snakebites in humans in ways that echo the increased predation pressure of snakes on their prey.
We thus ask whether snakebites reported in Costa Rica (CR) from 2005 to 2013 were associated with meteorological fluctuations. We place emphasis on El Niño Southern Oscillation (ENSO), a climatic phenomenon associated with cycles of other neglected tropical diseases (NTDs) in the region and elsewhere. We also ask how spatial heterogeneity in snakebites and poverty are associated, given the importance of the latter for NTDs. Here, we found that periodicity in snakebites reflects snake reproductive phenology and are associated with ENSO. Snakebites are also more likely to occur following hot temperatures and can be significantly reduced after rainy years. Nevertheless, snakebites cluster in the areas with the heaviest rainfall in CR, increase with poverty indicators and decrease with altitude. Altogether, our results suggest that snakebites might be varying as a result of ongoing climate change.
