Abstract

Introduction: Snakebites are a public health problem affecting tropical countries in Africa, Asia, and Latin America. In Angola there are no rigorous statistics or scientific studies that allow us to know the situation of the country. Objective: to characterize snakebite accidents in Benguela province, in the period 2019-2021. Material and Method: Observational, descriptive, cross-sectional, and prospective study. Universe made up of the total number of families in the municipalities with the highest incidence: Cubal, Lobito, Caimbambo and Chongoroi. The sample size was calculated with a 95% confidence level for a total of 124 households, represented by 1014 people. The residences were selected by simple random sampling. A structured interview was given to the head of the family, with prior informed consent. Data were analyzed in SPSS through absolute frequencies and percentages. Results: Of the heads of household, 73.3% are men, 76.6% work in the fields and 56% had primary education. Of the total number of people, 2.6% were bitten by snakes (26 people) and 3 died. Of the survivors, 13% had physical sequelae. Regarding knowledge, 64.5% identified it as the place with the highest incidence at home, 33.8% from 6 pm to 12 pm, 48.3% in the summer season, 100% applied traditional treatments, 94.4% correctly identified at least one, and 70.9% recognized bitis arietans. Regarding prevention measures, 49.1% do not know, although of the remaining 54.8% consider it better to wear shoes or boots. Conclusion: Angola needs to continue and increase community education programs to alleviate human suffering.
