[Risk of tuberculosis infection in the health jurisdictions of Jalisco, Mexico].
This paper reports an evaluation of the risk of tuberculosis infection in school children in the sanitary jurisdictions of Jalisco, Mexico. It also compares the official figures of incidence of smear-positive pulmonary tuberculosis with those estimated with this epidemiological indicator. The study included 6,469 first grade children, six to seven years old, from 95 state schools. We skin-tested 4,260 of them with 2 TU PPD. Sixty per cent of the children tested were vaccinated with BCG. This proportion varied between the jurisdictions: from 43 per cent in Tepatitlan to 70 per cent in Ameca. The rate of tuberculosis infection was 6.3 per cent, with differences between children with a BCG scar and those with no scar (7.4% and 4.4%, respectively). We also found differences in the annual risk of infection between the jurisdictions. The annual risk was 0 per cent in Lagos de Moreno and 1.60 per cent in Ameca. With the exception of two jurisdictions, the incidence of smear-positive pulmonary tuberculosis estimated with this indicator is several times higher than that officially reported.
