Envenenamiento ofídico en Costa Rica: logros y tareas pendientes / Snakebite envenoming in Costa Rica: achievements and pending tasks

Resumen Objetivo: Efectuar un análisis de los logros en Costa Rica en cuanto al problema de los envenenamientos por mordeduras de serpientes, y señalar tareas pendientes para reducir aún más el impacto de esta patología. Metodología: Se efectuó una revisión de bibliografía relacionada con el estudio del envenenamiento ofídico en Costa Rica y con los avances efectuados en el tema, en el país. Paralelamente, se identificaron aspectos que requieren atención en el manejo de esta enfermedad tropical desatendida. Conclusiones: Desde las primeras décadas del siglo XX, se han realizado avances significativos en la comprensión y manejo del problema de los envenenamientos por mordedura de serpiente en Costa Rica. Se ha trabajado desde una visión integral que incluye: investigación científico-tecnológica, producción y distribución de antivenenos, esfuerzos en prevención, capacitación de las personas profesionales de la salud en el diagnóstico y tratamiento, y docencia de grado y posgrado en el tema. El país ha asumido un papel de liderazgo a nivel internacional, tanto en el plano académico como en la provisión de antivenenos a muchos países. No obstante, aún quedan aspectos del problema que requieren nuevos esfuerzos en nuestro medio, sobre todo en lo referente a la atención de las consecuencias biomédicas, psicológicas, sociales y económicas que sufren las personas afectadas.

Abstract Aim: To analyze the achievements made in Costa Rica in confronting the problem of snakebite envenomings, and to identify pending tasks to further reduce the impact of this pathology. Methods: A review of the literature on snakebite envenomings in Costa Rica was carried out, identifying the main achievements reached in the country. In parallel, issues that require renewed attention in the management of this neglected tropical disease were identified. Conclusions: Since the first decades of the 20th century, significant advances have been made in Costa Rica for understanding and confronting the problem of snakebite envenomings. An integrative perspective has been implemented, which includes scientific and technological research, production and distribution of antivenoms, prevention campaigns, training of health professionals in the diagnosis and treatment of envenomings, and teaching at graduate and undergraduate levels. Costa Rica has had a leading international role in this topic at the academic level, and by providing antivenoms to many countries. Nevertheless, there are issues that require further efforts, especially regarding the attention to the biomedical, psychological, social and economic consequences suffered by people affected by snakebites.

Circumstances and Consequences of Snakebite Envenomings: A Qualitative Study in South-Eastern Costa Rica.

A qualitative study was carried out in south-eastern Costa Rica on the circumstances and consequences of snakebite envenomings. This region has the highest incidence of snakebites and the lowest per capita and per family income in the country. There is a high degree of destitution and an unstable labor situation in the region. This study was based on semistructured interviews with 15 people who had suffered snakebite envenomings. This sample size was established on the basis of data saturation. Bites occurred mostly while doing agricultural work, either as salaried workers, as occasional workers, or working on their own. Although all people were attended in health centers of the public health system, and received antivenom free of charge, the majority of them did not receive compensation or rehabilitation upon discharge from the health facilities as a result of not being regular salaried workers. People described many difficulties as a consequence of these envenomings, such as permanent physical sequelae, including two amputations, psychological consequences, economic hardships, and difficulties for reinsertion into agricultural work. In spite of the significant advances that Costa Rica has made for reducing the impact of these envenomings, results reveal issues that require urgent attention by government and civil society organizations, to compensate for the physical, psychological, social, and economic consequences of these envenomings.
