Tuberculosis screening for international students.

Nonimmigrant, international students entering colleges in the United States are not required to undergo screening for tuberculosis (TB). Thirty-nine percent of active TB cases in the United States are in foreign-born individuals. In an effort to minimize the occurrence of active TB on a community campus with an increasing international student population, the college health service implemented a TB-screening policy for all newly enrolled international students. For the 1997/98 school year, 171 international students from 70 different countries enrolled in classes. Fifty-nine students (35%) screened for TB had a positive skin test (greater than 10 mm induration). Of those, 34 initiated isoniazid therapy, and 27 successfully completed the prescribed regimen under supervision of the campus health office.
