In 168 patients lung tuberculosis and in 15 cases-extrapulmonary tuberculosis was recognized. Strongly positive tuberculin skin test as a single sign was observed in 134 patients. 182 children with recognised tuberculosis were treated with antituberculous drugs, and in 132 children chemoprophylaxis (INH) was applied. Tuberculosis of tracheo-bronchial lymph nodes was the most frequent form.
