BOADAS, Jesús et al. Eco-epidemiological profile of snakebite accidents in Monagas state, Venezuela (2002-2006). Bol Mal Salud Amb [online]. 2012, vol.52, n.1, pp.107-120. ISSN 1690-4648.

The accidents caused by venomous animals are a global problem, especially in subtropical and tropical regions of the world. In Venezuela, they are endemic in several regions including the northeast. In order to expand and update the ecoepidemiological profile of snake bites in Monagas state, their behavior was assessed in each municipality for 5 years (2002 -2006). There were 339 ophidian accidents (on average 68 per year). The bites occurred more frequently in young adult male farmers, while working in the field and during daytime. The incidence followed a bimodal seasonal pattern with predominance in high and low rainfall periods. Bothropic envenoming (28.6%) were the most frequent followed by Crotalic ones (14.5%), with a 2:1 ratio. 87.9% received specific serum therapy. The annual average incidence in the state was 11.30 cases per 100,000 inhabitants. Punceres (46.29), Acosta (20.91) and Bolivar (19.52) were the municipalities with the highest impact. Monagas state showed an endemicity map with municipalities having (1) very high endemicity, (2) high endemicity, (3) medium endemicity, (4) low endemicity and (5) very low endemicity. In the studied period there were no deaths from this cause in the state. The findings suggest the importance of snake accidents in Monagas, especially in the northern half of the state.
