ABSTRACT

Objective. To establish the seroprevalence of infection by Leptospira in an occupational setting in Cordoba. Material and methods. A cross-sectional study was conducted among 334 farmworkers, butchers, and garbage collectors, to identify the presence of anti-leptospira IgM antibodies, in the Department of Cordoba, Colombia. Stratified sampling proportional to the number of inhabitants and occupation was used to select the sample population (confidence level 99.9%, error 0.5%, prevalence 72%). The SPSS software 11.0 version was used to perform non parametric tests with p‹0.05, as well as odds ratios with confidence intervals. Results. The prevalence of previous infection by Leptospira was high (13.1%). No differences among areas were found, however, higher infection was associated with living in Cienaga de Oro municipality (OR= 3.52 CI 1.70-7.26) (p=0,00283). Being a farmer was also a risk factor for infection (OR= 2.04 CI 1.080-3.85) (p= 0.025), as well as drinking water from a dam (OR= 2.4 CI 1,24-4,70) (p= 0.00787). Conclusions. The rate of infection is important and a significant public health problem in this area of the Colombian Caribbean coast.
