    Abstract:
    BACKGROUND: To study the epidemiology to tuberculosis (TB) in Barcelona, Spain from 1987 to 1995, analyzing the influence of HIV infection and the impact of control measures. PATIENTS, MATERIAL AND METHODS: All cases detected by the Barcelona Tuberculosis Prevention and Control Program were included in the study of the evolution of TB incidence according to different variables. The impact of HIV infection was analyzed through the attributable risk per cent (AR), and control measures through the evolution of the rate of treatment compliance, contact studies, and diagnostic delay. RESULTS: We detected 8,942 patients, 23.2% of whom were found through the active epidemiological surveillance system, representing an average annual incidence of 60.4/100,000. The incidence peaked in 1991 (68.7/100,000) and slowly declined to 55.7/100,000 in 1995. Men showed higher incidence (RR: 2.74; CI 95%: 2.62-2.87), particularly among the young (25-34 years olds), 53.3% of whom were HIV (+). The AR for HIV was 92.7%. In this period there was an increase in TB HIV (+), IVDU, and prisoners. Treatment compliance (80.8% in 1987 to 93.8% in 1995) and contact studies (3.2 studies/case in 1995) evolved favorably, unlike but diagnostic delay (35 days in 1995) did not. CONCLUSIONS: The Active Epidemiological Surveillance System has affored us a clear view of the actual situation regarding TB in Barcelona, Spain. Despite the HIV epidemics and the high number of IVDU, the evolution of TB has shown a steady decline due to improvement in control measures.
