Eastern Michigan University officials say a student diagnosed with tuberculosis earlier this month appears to be an isolated case.

The Washtenaw County Public Health Department has completed testing on other students who were in contact with the affected student, officials said. The health department concluded there are no active TB cases among the international student’s co-workers at the EMU Eateries, or among any EMU staff or students who came into close contact with the student, officials said.

Health officials and EMU officials have worked together to find and test anyone who might have had contact with the affected student, a press release said.

Ellen Gold, executive director of University Health Services, said the county health department doesn't anticipate any other active cases. The affected student is receiving appropriate medical care at this time, Gold said in a release.

TB is typically spread through prolonged close contact, usually through respiratory contact. Health officials say they don't believe the illness would have spread through casual contact with any food.

Washtenaw County averages about six to 10 cases of TB every year, with the majority of cases being foreign-borne. In 2008, 10 active cases of TB were identified.

TB is a contagious bacterial infection that mainly involves the lungs, but may spread to other organs. Symptoms can include cough, coughing up blood, excessive sweating, fatigue, fever, and unintentional weight loss.

Treatment usually lasts for six months, and most people diagnosed in the United States will recover from primary TB infection without further evidence of the disease.
