[Problems in prevention of tuberculosis during the childhood conversion period].

An inclusive review of the tuberculosis measures including the tuberculosis control law was proposed, and the discontinuation of BCG re-vaccination and school medical examinations was executed in pediatrics area in the year 2003. Moreover, single time vaccination for infants is basic, and the direct BCG vaccination is introduced as a rule. The childhood tuberculosis measures are exactly at a turning point. A group and uniform care which we have executed so far is inefficient. A basic idea of the revision is to introduce an individual and intensive care for high risk and dangerous groups first of all, and to convert to the efficient measures. We have to enhance the contact examinations, administer chemoprophylaxis to patients thoroughly, improve the quality of medical treatments, ask medical institutions to examine symptomatic persons, and strengthen the system of childhood tuberculosis surveillances.
