title: [Preliminary evaluation of the prevalence of tuberculosis infection in an occupational risk group].
abstract: BACKGROUND
  The aim of this study was to gain knowledge on the prevalence of tuberculosis infection in occupational groups whose professional activity could implicate a high risk of contact with persons infected with Mycobacterium tuberculosis. Additionally, we sought to identify risk factors in order to establish effective measures for control and prevention. With this aim we carried out a pilot study among members of our police force.
  
  
  METHODS
  Reactivity against tuberculin was tested in 150 individuals belonging to the Spanish National Police Force and an epidemiological survey was conducted to identify risk factors.
  
  
  RESULTS
  The prevalence of tuberculin reactivity was 10.7%. No correlation was found between positive testing and sex or years of service, but there was a correlation with respect to age.
  
  
  CONCLUSIONS
  The prevalence data and the experience obtained in this pilot study enable us to continue working toward the establishment of an effective control program.
