title: Tuberculosis incidence in Turin, Italy, 1973-1999.
abstract: METHODS
  Turin, Italy, 1973-1999.
  
  
  OBJECTIVE
  To estimate tuberculosis (TB) incidence rates in Turin between 1973 and 1999.
  
  
  METHODS
  Incidence study. An active search of new TB cases was carried out by examining the clinical records of the three major TB care services in the city. New cases were defined as patients treated for the first time. To evaluate the completeness of this series, data were linked with the TB Notification Register and the Regional Hospital Discharges Register for the years 1997-1999.
  
  
  RESULTS
  TB incidence rates declined from 25.6 cases per 100,000 population in 1973 to 6.4 in 1999. TB/human immunodeficiency virus (HIV) co-infection increased after 1985, reaching a peak (16.5%) in 1994-1996, and significantly decreasing in 1997-1999. Foreign-born cases started to increase after 1988, reaching 25.8% of total cases in 1997-1999. TB infections in Italian-born, non-HIV-infected cases occurred mostly among the elderly, while HIV/TB co-infections and TB in immigrants occurred mostly in younger age groups. The study captured 59% of cases diagnosed in Turin in 1997-1999.
  
  
  CONCLUSIONS
  In recent years, new cases of TB have been diagnosed mostly among HIV-positive people and immigrants. Preventive and control strategies should focus on these population groups, improving quick identification and effective treatment of cases, and implementing accessible services.
