Abstract

Ophidian accidents caused by snakes of the Viperidae family have become a factor of concern for public health, due to the high incidence of accidents, where the North region is characterized by presenting the highest rate of injury in Brazil. Tocantins, belonging to the legal Amazon region, has environmental aspects that can interfere with the movement and behavior of these animals, such as climatic and vegetation conditions. Porto Nacional is a municipality in Tocantins that is in a region with a high incidence of snakebites, whose epidemiological aspects need to be constantly monitored. Therefore, the objective of this study was to analyze the epidemiological profile of snakebites for the municipality of Porto Nacional, in the 2015-2019 gloss. With data available by the Information System for Notifiable Diseases - SINAN, the number of accidents, the gender with the highest incidence, the profile of the injured patient, the severity and treatment, as well as the place of occurrence, month and year of the incident. The relationship of accidents over the period under study and the correlation with climatic factors (rainfall, humidity and temperature) were also evaluated. 145 cases were recorded, with the majority of accidents caused by the Bothrops gender, with the most affected victims of the male sex (69%), occurring in the rural area (68%), with predominance of mild and moderate clinical manifestations, and treatment with antivenom. There was no significant increase in snakebite accidents in the years under study, nor was there a monthly correlation with climatic factors. Thus, it is concluded that the snakebite in Porto Nacional maintains the classic national pattern of the snakebite accident, with the need for continuous actions to guide the population in order to minimize the impacts with the snakes.
