title: [Occupational leptospirosis in a Colombian Caribbean area].
abstract: OBJECTIVE
  To establish the seroprevalence of infection by Leptospira in an occupational setting in Cordoba.
  
  
  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 Cl 1.70-7.26) (p = 0,00283). Being a farmer was also a risk factor for infection (OR = 2.04 Cl 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.
