ABSTRACT

Introduction: Evaluation of Mycobacterium tuberculosis transmission risk in health care facilities is necessary to implement effective infection control programs.
Objective: To assess the risk of Latent Tuberculosis Infection in Primary Health Care workers at La Lisa municipality.
Methods: A cross sectional study in Primary Health Care workers from five polyclinics of La Lisa municipality, Havana City, from 2009 to 2011 was performed. A tuberculin skin test was applied along with an interview on personal data and exposition to M. tuberculosis. The prevalence of Latent tuberculosis Infection for each area were calculated, as well as the distribution of individual and collective risk. To prove the possible influence of predictor variables on the presence of infection, a bivariate analysis using the Prevalence Risk Ratio was applied.
Results: Most of the staff (75,1 %) are at minimum risk. Elpidio Berovides polyclinic had most PHCW at minimum risk (84,4 %) and fewest at high risk (11,3 %). Those Primary Health Care workers at minimum risk had the lowest prevalence of Latent Tuberculosis Infection. Laboratory, amily Doctor Offices, Sexual Transmitted Diseases and Hygiene & Epidemiology departments, were evaluated at higher risk.
Conclusions: The individual and collective risk in these Primary Health Care workers was low to very low. The low tuberculosis infection transmission in these workers of La Lisa could be related with the low incidence of Mycobacterium tuberculosis in the local population.
