[Dynamics of the morbidity in children with tuberculosis in the Irkutsk region].

The ratio of morbidity in adults and children was 4.3:1 and 3.5:1 in 1981 and 1997, respectively. This suggests that the tuberculosis situation was poor in the region. The clinical manifestations of childhood tuberculosis changed with a rise in its morbidity. The course of tuberculosis became more severe; younger children were more commonly affected; there was a trend for its chronic course. Concomitant forms at extrapulmonary sites were more frequently detected. Tuberculosis of intrathoracic lymph nodes was prevalent, its proportion being 78%.
