title: [Tuberculosis in Italy: available data and open questions].
abstract: OBJECTIVE
  To describe the epidemiological trend of tuberculosis (TB) in Italy.
  
  
  METHODS
  Descriptive study on the basis of routine information sources: TB deaths (1955-1993) and TB notifications (1955-1995). To identify persons with AIDS (PWAs) among notified TB cases, a record linkage with the National AIDS Registry was performed.
  
  
  RESULTS
  From 1955 to 1993, the TB mortality constantly decreased by a mean of 7.6% per year. From 1955 to 1995, the crude annual total incidence of TB decreased from 25.26 to 9.12 per 100,000. The trend of decrease of pulmonary TB ceased in 1980, whereas the incidence of extrapulmonary TB began to markedly increase in 1980. Between 1992 and 1995, the average annual meningitis notification rate in children < five years was 0.045 per 100,000. In 1995, the curve of incidence rates by age shows two peaks (> 75 years and 25-34 years). Persons with AIDS and foreigner-born persons represented in total 11.3% of TB cases (1992-1995); in the age class 25-34 years, this proportion was 32.5% (34.1% in 1995). A considerable undernotification of TB among PWAS was detected.
  
  
  CONCLUSIONS
  The TB incidence is no longer decreasing due to the changes of TB case definition in 1987 and the.
