Temporal trend and epidemiological profile of accidents caused by venomous animals in the state of Pará, 2018-2022

Abstract

Accidents involving venomous animals are a significant public health issue in Brazil, with about 140,000 cases reported annually. Pará, with its vast forests and biodiversity, experiences high incidences exacerbated by human-environment interactions. This study analyzes the temporal trend and epidemiological profile of such accidents in Pará from 2018 to 2022. A cross-sectional study using SINAN data, employing Prais-Winsten linear regression to evaluate temporal trends. Incidences were stratified by sex, age group, and accident location (rural, agricultural, work, residential, leisure). From 2018 to 2022, accidents in rural areas, particularly agricultural, increased notably, with a 40% rise overall. Males aged 20-39 years were most affected. March consistently recorded the highest cases, indicating a seasonal peak. Accidents involving venomous animals in Pará are increasing, particularly in areas of agricultural expansion. This trend highlights the need for intensified prevention efforts, public education, and effective treatment strategies, integrating public health measures and environmental management.
