Temporal trend and epidemiological profile of accidents involving venomous animals in Brazil, 2007-2019.

OBJECTIVE

to analyze the temporal trend of accidents involving venomous animals in Brazil from 2007 to 2019.

METHODS

this was a cross-sectional study carried out with data from the Notifiable Health Conditions Information System (SINAN). Prais-Winsten linear regression was used for the temporal analysis. We calculated incidence rates according to sex and age group, relative risk and case fatality ratio.

RESULTS

during the study period there were 2,102,657 cases of accidents involving venomous animals. With the exception of snakebite, the remaining accidents showed a rising temporal trend in most regions of the country. Scorpion stings, snake bites and spider bites were responsible for 86% of accidents, mainly affecting male people of working age. Accidents involving snakes (0.4%) and bees (0.3%) had the highest case fatality ratios. Children were the main victims of accidents involving bees, caterpillars and "others".

CONCLUSION

accidents involving venomous animals showed a rising temporal trend for most conditions, as well as different epidemiological profiles.
