TROY, Ala. (AP) — The Alabama Department of Public Health and Troy University are investigating a case of active pulmonary tuberculosis that was identified in a student.

State health officials notified the university Wednesday that they were investigating a case of TB found on the university's main campus.

WSFA-TV reports students enrolled in classes with the infected student, as well as faculty and staff who might have been in close contact with the student have been notified. Those who have been contacted will be tested Oct. 24 on campus.

State health officials say TB is an airborne disease that can be spread when someone with an active case coughs, speaks or sings in a small, enclosed space with other people. Symptoms include cough of more than two weeks' duration, shortness of breath and fever.
