“…11 Sporadic outbreaks and reports of seroprevalence in specific populations reveal that human leptospirosis is more common in Chile than the reported annual incidence rates suggest and that geographical variations exist. 12,13 The Los Rios Region in Chile, where this study took place, is a prominently agricultural and farming area with scattered urban settlements. A local serosurvey in people with occupational risk revealed significant evidence of human exposure (22%), 14 and surveys in animals report that leptospirosis in domestic animals, including sheep 15 and dogs, 16 is common.…”

Abstract. Rodents are well-recognized reservoirs of Leptospira, contributing to its maintenance in endemic areas and playing a role in the public health risk associated with the infection. This study sought to provide some insights into rodent populations from Chile and their Leptospira carriage. In total, 393 rodents were trapped in 177 households. Higher rodent counts were associated with year 2 of the study, rainfall, and number of rodent signs. There was an inverse correlation with the number of cats. The number of rodents was higher in villages compared with slums (rate ratio = 3.23) but modified by average household age. Eighty rodents (20.4%) tested positive for Leptospira: 19.7% on the farms, 25.9% in villages, and 12.3% in the slums. Prevalence was 22.5% in Mus musculus, 20.7% in Rattus rattus, 21.1% in wild rodents, and 10.3% in R. norvegicus. Seasonal and temporal effects were the major determinants of Leptospira infection in rodent populations.

“…Es importante la implementación continua de campañas educativas con el fin de concientizar y disminuir los riesgos de infección en comunidades; ya que en población a riesgo la incidencia acumulada para las zoonosis en veterinarios de Argentina fue del 34,1% (MOLINERI et al, 2013), y en un estudio retrospectivo determinaron que hay una correlación directa entre mayor número de casos en animales y casos humanos (MARTÍNEZ et al, 2012).…”

ResumenLa leptospirosis, es una zoonosis de carácter reemergente, de distribución mundial y con diversa sintomatología, de gran incidencia en las regiones tropicales, donde los reservorios suelen ser animales domésticos y salvajes que excretan por la orina el microorganismo y son la fuente de contaminación para humanos y otros animales, siendo un serio problema de salud pública. También es considerada como enfermedad profesional por su alto riesgo de exposición. En el humano, la sintomatología de la infección es variada y en muchos casos pasa desapercibida. El objetivo general fue conocer la seroprevalencia de anticuerpos de Leptospira interrogans (sensu lato) y por medio de un estudio epidemiológico transversal en 62 trabajadores de granjas porcinas en tres municipios del medio Sinú, se recolectaron muestras de sangre y la realización del MAT se implementó con 14 serogrupos. La seroprevalencia en los trabajadores fue del 75,81% y los serogrupos que presentaron las mayores frecuencias fueron: Canicola, Pomona, Icterohaemorrhagiae y Grippothyphosa. AbstractLeptospirosis is a reemerging zoonotic character, worldwide distribution and with different symptoms, high incidence in tropical regions, where the reservoirs are usually wild and domestic animal urine excreted by the microorganism and are the source of contamination for humans and other animals to be a serious public health problem. It is also considered as an occupational disease because of its high risk of exposure. In the human symptoms of infection are varied and in many cases are unrecognized. The overall objective was to know the seroprevalence of antibodies to Leptospira interrogans (sensu lato) and by a transverse epidemiological study in 62 workers of pigs farms in three municipalities of the medium Sinu blood samples and the completion of the MAT were collected, was implemented with 14 serogroups. The prevalence in workers was 75.81% and serogroups that presented the highest frequencies were: Canicola, Pomona, Icterohaemorrhagiae and Grippothyphosa.

“…Como referencia, de los infectados, aproximadamente 20 a 25% desarrollarán una cardiopatía o megadigestivos y de éstos, 5 a 10% tendrán una cardiopatía grave, potencialmente mortal 13 . Para la hidatidosis se reporta una letalidad de 1,3% 14 ; para el síndrome cardiopulmonar por hantavirus entre 30 y 47% 15 y para leptospirosis entre 5 y 20% 16 . Es decir, incluimos en este estudio enfermedades que van desde baja a alta letalidad.…”
