MONTGOMERY, Ala. (AP) - Officials at Alabama State University and the state Department of Public Health say they're investigating a case of pulmonary tuberculosis at the school. Assistant state health officer for disease control and prevention Mary McIntyre says the ADPH is working closely with the university to administer precautionary testing, investigation and control. Health officials say they've been identifying students and faculty who may have come into close contact with the student and officials have emailed about 600 students and faculty to tell them how and where they can be tested. The university requires all students to show documentation before beginning classes to prove they've tested negative for TB. Officials say the student presented documentation before the 2013 fall semester.
