[Factorial analysis of the epidemic and infectious processes of tuberculosis in children].

The direction and strength of a relation and a correlation between the parameters of an epidemic process of tuberculous infection were estimated by correlation and regression analyses where r is the correlation coefficient verging to one. A high correlation was found between the risk for infection with Mycobacterium tuberculosis and the quality of measures aimed at isolating the source of infection--a bacteria-isolating adult. The morbidity rates in children with tuberculosis depend on the quality of preventive measures to a greater extent.
