title: [Microepidemics of tuberculosis].
abstract: Persons with unknown tuberculosis exist even in countries with favourable situation of tuberculosis and contribute to the transmission of tuberculosis. The features and characteristics of 12 tuberculosis microepidemics observed in Czech Socialist Republic (10 mil. inhabitants) in 1983 to 1987 are described. The intensity of transmission of tuberculous infection is determined by the amount of tubercle bacilli excreted and by the duration of exposition. In 10 source cases bacilli were detected by direct smear examination. Eight microepidemics occurred in families, 4 at school. Prolonged close contact, as well as occasional exposure to the infection were demonstrated. There were infected 109 children and adults. Tuberculosis developed in 27 children and adults. The examination and follow-up of persons in contact with tuberculosis patients belong to the important control procedures.
