[Improving ambulatory services for children in the foci of tuberculosis with special reference to the factors of increased risk of infection].

The paper deals with the results of the examination of certain factors that increase the risk of children's contamination in tuberculosis infection foci. It has been established that primary infection takes place more frequently in children under 6 years of age (1.3-fold), in children who do not attend preschool establishments (2-fold), in those having inappropriate BCG vaccination and revaccination (2.4-fold) and in the foci where patients abuse alcohol (2.2-fold). These children comprise a group of especially high contamination risk. It is expedient to check up them 3 times a year, performing a tuberculin test in children showing an uncertain response, to conduct clinical and X-ray examinations in accordance with the indications and to strictly controlled chemoprophylaxis. The proposed scheme of children's medical examination is one of the pattern to make better therapeutic and preventive measures in tuberculosis infection foci.
