ABSTRACT
An exhaustive search for the clinical records of patients diagnosed with tuberculous disease was done in the hospitals of the area under study, which involves 392,000 population. During the years 1992, 1993 and 1994. There were included: 1) patients who had positive bacilloscopy and/or positive Lowenstein's culture in any specimen: 2) patients younger than 35-years-old who had pleural effusion, significant Mantoux and adenosine deaminase (ADA) over 47 U/I in the pleural effusion. In total 814 patients remained in the study with an average age of 38.39(19.39 DE) in 1992, 39.02 (20.04 DE) in 1993, and 34.1 years-old (19.2 DE) in 1994, with extreme ages of 2 months and 87 years-old. The incidence/100,000 H was: in 1992: 67.86, in 1993: 66.58 and in 1994: 73.2. The contagious forms incidence/100,000 H was: 1.5 in 1992 and 1993; and 1.79 in 1994. The hospital mortality incidence/100,000 H was 2.04 in 1992, 2.30 in 1993 and 2.6 in 1994. We conclude that tuberculosis is endemic in our area with moderately high and stationary incidence.
