[Prevention, diagnosis and treatment of tuberculosis].

Current incidence of tuberculosis (7B) in Japan is 14.4 per 100,000 populations, which is higher than the western countries. Inhalation of TB bacilli is difficult to control except for using N95 respirator in a medical facility. BCG is effective to prevent from serious TB disease especially for children. Latent tuberculosis infection treatment is recommended in order to attain low incidence. Early diagnosis is most critical for prevention. It is important to suspect TB for those having cough more than two weeks and do chest radiograph as well as bacterio logical examinations with good sputum specimen. Treatment should be given observing National Standard of TB Care under proper patient support for adherence in collaboration with health center.
