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.
即使在结核病疫情良好的国家，也存在结核病感染情况不明的人群，他们会导致结核病的传播。本文描述了1983年至1987年在捷克斯洛伐克社会主义共和国（1000万人口）观察到的12起结核病微观流行的特征。结核感染的传播强度取决于排出的结核杆菌数量和接触时长。在10例传染源病例中，通过直接涂片检查检测到了结核杆菌。8起微观流行发生在家庭中，4起发生在学校。证实存在长期密切接触以及偶尔接触感染的情况。共有109名儿童和成人受到感染。27名儿童和成人患上了结核病。对结核病患者接触者的检查和随访属于重要的防控措施。
