[Snake bite epidemiology in the last 100 years in Brazil: a review]

Abstract

We review 30 studies on snake bites in Brazil, published from 1901 to 2000, and conclude that epidemiological analyses conducted in the last 100 years are based on the same variables already identified by Vital Brazil in his pioneering report, i.e., characteristics of the individuals prone to snake bites, the bites themselves, and treatment. The original epidemiological profile was also maintained over the years and indicates that such accidents are more frequent among male farm workers in the 15-49-year age bracket, affecting mainly the lower limbs, and caused by snakes from genus Bothrops.
