title: [Human mortality due to invertebrate and vertebrate envenomation in Monagas State, Venezuela].
abstract: Human mortality due to envenomation by animals in Monagas state, Venezuela was evaluated. In this state 47 deaths due to envenomations produced by vertebrates and invertebrates (scorpions = 21, snakes = 20, bees = 6) during the period 1980-2000 were registered. The mountainous area, at the north of the state (Turimiquire sub-region) and its piedmonts reported most of the mortality by scorpionism (57.2%) and ophidism (70.0%). The age group of the patients was related with the sort of envenomation causing the death. During the period of dry season the highest percentage of deaths by scorpions and bees occurred; and the deaths produced by snakes were more frequent in the median raining season. The most frequent causes of death (61.9%) by scorpionism were the acute lung edema and congestive heart failure. In 40% of the deaths caused by snakes, alterations of the blood coagulability were observed. Bee envenomation was responsible of 50% of the deaths produced by anaphylactic shock. In none of the deaths, the species responsible of the accident was identified. The annual mean mortality rate/100,000 inhabitants, in the 21 years registered was 0.20 for the scorpion envenomation, 0.19 for ophidism and 0.06 for bee envenomation. The data suggest the importance of the mortality produced by scorpions and snakes, particularly at the north of the state.
