[Epidemiology of childhood tuberculosis in the Basque Autonomous Community 1980-89. Efficacy of BCG vaccination].
The cases of tuberculosis in the Pediatric Units of the Basque Autonomous Community during the period of 1980-89 were studied. The annual incidence rate in the 0-4 year old age group was 5.8 per 100.00 in Biscay (95% confidence interval: 4.0-7.6), 5.9 (2.3-9.5) in Alava and 16.7 (12.7-20.7) in Guipúzcoa. Out of the 263 registered cases, 55 (21%) corresponded to meningitis and/or miliaria, 194 (74%) to respiratory tuberculosis and 14 (5%) to other clinical forms. Of these cases, the diagnosis in 83 (32%) was based on results from microbiological cultures, in 8 (3%) on histological examinations and in the remaining 172 (65%) on other diagnostic criteria. In 226 cases (86%) no scars were found nor were there any antecedents of BCG vaccination. In 32 patients (12%), there were scars or antecedents of BCG vaccinations and in 5 cases no information was available. The estimated protective effect of the BCG vaccination in the 0-4 year old group was 88% and in the 5-14 year old group 63%. We recommend that the efficiency of the BCG vaccination program be studied in order to assess the need of this program.
