Introduction: In the health sector, Tuberculosis is considered as a high risk disease for workers. Objectives: The main objective of this report is to study the prevalence of the Latent Tuberculosis Infection (I.L.T.) in two hospitals of the Area 2 of Madrid and the distribution of this infection among the clinical categories and services. Material and methods: Transversal study. We have analyzed 455 health workers of the University Hospital "La Princesa" and children's Hospital "El Niño Jesús". The study began in 2006 and ended in 2009. The analyzed variables have been age, sex, type of hospital, professional category and clinical services. Results: The prevalence of the observed latent tuberculosis infection has been of 11.4% (8.3%-14.1%). No significant differences have been observed between type of hospital, clinical services, professional category and sex. Age has been pointed out as a significant factor with an Odds Ratio of 1.05 (1.02-1.08). Conclusions: In our area of study the I.L.T. in health workers is approximately 10% , and this is not related with professional category but with age.
