title: [Trends in the incidence of tuberculosis in the area of Seville-South (Spain) during the 1990s].
abstract: OBJECTIVE
  To describe the incidence of tuberculosis (TB) in the hospital area of Seville-South between 1990 and 1999.
  
  
  METHODS
  Study of the incidence of TB in the area's population between 1990 and 1999 by way of periodic survey of informants who were likely to see cases.
  
  
  RESULTS
  The annual incidence of TB rose from 1990 (26.64/105) to its peak in 1992 (38.3/105), stabilized between 1992 and 1995, and later fell to 15.7/105 in 1999. Bacillary cases followed a similar pattern, with a peak of 13.76/105 in 1992 and a low of 6.06/105 in 1998. The annual incidence of TB-AIDS rose between 1990 (2.63/105) and 1995 (9.08/105), and then fell to 4.13/105 by 1999. The highest incidences were in the 25-to-34-year-old range in the periods from 1990 to 1993 (50.74/105) and 1994 to 1996 (61.49/105), whereas the incidence decreased among 55-to-64-year-olds (28.55/105) from 1997 to 1999. The age distribution was affected by rates in the TB-AIDS group, which contributed 48%, 50% and 55% in each period, respectively, for individuals in the 25-to-34-year-old range.
  
  
  CONCLUSIONS
  The annual incidence of TB was 41,1% lower in 1999 than in 1990, as a result of the marked decrease beginning in the middle of the decade. The impact of TB-AIDS patients on the evolution of annual incidence and on age distribution was considerable throughout the decade.
