RESUMEN
Introducción: La leptospirosis es una enfermedad zoonotica de distribución mundial que afecta a los animales domésticos y salvajes, que eliminan el microorganismo por la orina. Los seres humanos son huéspedes accidentales y pueden presentar desde una enfermedad leve y autolimitada hasta una enfermedad mortal con insuficiencia multiorgánica. Objetivo: Determinar la prevalencia de 13 serovares de Leptospira en sueros de humanos ubicados en 20 localidades del Distrito Capital. Método: Estudio epidemiológico transversal entre agosto del 2006 y marzo del 2007, luego de procesar 1.307 sueros de humanos. Resultados: Los 1.307 sueros de humanos procesados se enfrentaron a 13 serovares, de los cuales resultaron positivos 165 sueros (230 reacciones positivas) y negativos resultaron 1.142 sueros. Se utilizo la icroaglutinacion (MAT) como la prueba serológica de referencia para el diagnostico de esta enfermedad. La prevalencia determinada para humanos fue de 12,62, situación que refleja la importancia de esta zoonosis. Conclusión: Es necesario desarrollar campanas de tipo educativo enfocadas en las personas en riesgo y en los propietarios de animales para que aprendan a reconocer estas zoonosis, con el fin de facilitar el diagnostico y el tratamiento. Palabras clave: leptospirosis, prevalencia, factores de riesgo, estudio epidemiológico, zoonosis.
ABSTRACT
Introduction: Leptospirosis is a world-wide spread zoonotic disease affecting domestic and wild animals, which eliminate the organism in the urine. Humans are accidental hosts and may get a mild and transient disease or even a fatal disease with multiple organ failure. The disease also compromises the health of animals. Aim: To determine the prevalence of thirteen Leptospira serovars in human serum samples taken from twenty zones in the Capital District. Method: A cross-sectional epidemiological study was done. The work was based on serological results obtained from 1,307 processed human serum samples. The work was based on the application of a structured epidemiological survey to people from the Capital District along four networks (20 zones). It was carried out between August 2006 and March 2007. Results: The 1,307 human serum samples were taken before 13 serovars (icterohaemorragiaeserogroup, serovars and copenhageniicterohaemorragiae; SerogroupAustralisserovarsaustralis and bratislava, canicolaserogroup, serovarcanicola; Cynopteriserogroup, serovarcynopteri; serogroup Pomona serovar Pomona; serogroupautumnalisserovarautumnale; serogroupshermanishermaniserovar, serogroupserovar Mini mini; serogroupserovar Hebdomadishebdomadis;serogroupserovar Bataviaebataviae; serogroupserovarGripotyphosagripotyphosa). 165 serum samples were positive (230 positive reactions) and 1142 were negative. Micro-agglutination Test (MAT) was used as the serological test to diagnose the disease. The prevalence was 12.62 for humans, which reflects the importance of this zoonosis. Conclusion: It is necessary to carry out educational campaigns targeted at persons at risk groups and pet owners so that they learn to recognize these zoonoses in order to facilitate the diagnosis and treatment.
