“…russelli actually serve as proxies for the abundances of non-envenoming species. Abundance surrogacy is relatively common among habitat generalists [ 54 ] and non-envenoming snakes are commonly involved in snakebite cases [ 55 ], resulting in decreasing risk with the abundance of those non-medically relevant species. In conclusion, given these population-level uncertainties related to the identity of the biting snakes, adequate clinical management in case of a bite should of course be based on expertise and careful clinical evaluation of the envenoming disease.…”

A mechanistic model of snakebite as a zoonosis: Envenoming incidence is driven by snake ecology, socioeconomics and its impacts on snakes

Snakebite is the only WHO-listed, not infectious neglected tropical disease (NTD), although its eco-epidemiology is similar to that of zoonotic infections: envenoming occurs after a vertebrate host contacts a human. Accordingly, snakebite risk represents the interaction between snake and human factors, but their quantification has been limited by data availability. Models of infectious disease transmission are instrumental for the mitigation of NTDs and zoonoses. Here, we represented snake-human interactions with disease transmission models to approximate geospatial estimates of snakebite incidence in Sri Lanka, a global hotspot. Snakebites and envenomings are described by the product of snake and human abundance, mirroring directly transmitted zoonoses. We found that human-snake contact rates vary according to land cover (surrogate of occupation and socioeconomic status), the impacts of humans and climate on snake abundance, and by snake species. Our findings show that modelling snakebite as zoonosis provides a mechanistic eco-epidemiological basis to understand snakebites, and the possible implications of global environmental and demographic change for the burden of snakebite.

“…Different snakes have different venom strengths. Among species only six are medically important (13) and others are mildly venomous or non-venomous. 96.8% of people had identified the cobra as highly venomous.…”

“…Alternatively, the estimated negative effects for these species could arise if the predicted abundances of N. naja and D. russelii actually serve as proxies for the abundances of nonenvenoming species. Abundance surrogacy is relatively common among habitat generalists [51] and non-envenoming snakes are commonly involved in snakebite cases [52], resulting in decreasing risk with the abundance of those non-medically relevant species.…”
