Aspectos biomédicos y epidemiológicos del accidente ofídico en el departamento del Cauca, Colombia, 2009-2018

INTRODUCTION: Snakebite is a relevant public health problem in Colombia, which is evident in epidemiological data at the Latin American level, where it ranks third place in the number of snakebites, after México and Brazil. OBJECTIVE: To perform a retrospective analysis of snakebite accidents in the department of Cauca between 2009 and 2018 based on the data from the Public Health Surveillance System of Colombia reported to the Health Institute of Cauca. MATERIALS AND METHODS: We compiled and interpreted the information from the compulsory snakebite notification forms for the study’s 10 years period. We determined snakebite incidence and frequency according to the geographical distribution and the causal agents, and we analyzed related socioeconomic variables as well. RESULTS: The records accounted for 1,653 cases and low mortality. Bothrops and Bothriechis species (77.43%) caused most of the accidents followed by Micrurus (2.9%). Most of the notifications came from the south of the department, and males and farmers were the most affected with bites mainly in the upper extremities. During poisoning, hemorrhagic manifestations predominated over necrosis and infections; serotherapy criteria were not always adequately applied, however, iatrogenic complications were not frequent. CONCLUSIONS: El Tambo and Piamonte municipalities, being male, and rural areas were the variables most affected by ophidism, mainly bothropic ophidism. The highest incidences occurred in the southern part of Cauca, in the Patía and Caquetá river basins.
