Tuberculosis screening in Kansas City homeless shelters.

Voluntary tuberculin skin testing, coupled with on-site radiographic examination of persons with indurations > or = 10 mm, was conducted in five home-less shelters in Kansas City. Of 856 skin tests administered, 654 were read and 89 (13.6%) were positive. Males were nearly four times as likely to have a positive skin test than females. None of the positive individuals had abnormal chest radiographs. Of 42 persons who initiated preventive therapy, only eight completed the course of treatment.
