[Tuberculosis epidemiology in Catalonia: 1982-1989].

The epidemiological indicators of tuberculosis in Catalonia and their trends since 1982 were evaluated. It was shown that the reported morbidity rate has increased because of an increased number of reports, but it probably is still lower than the real one. The epidemiological value of the parameters of tuberculous infection was also shown, particularly the yearly infection rate (YIR), or probability of an individual to be infected. In spite of the multiple interferences that these indexes may have undergone during the past BCG vaccination campaign, their reduction is very important, the yearly reduction of YIR being estimated in 11%.
