COLUMBIA, Mo. (AP) — University of Missouri officials say a student on the Columbia campus has active tuberculosis and may have infected other people.

The school announced Monday that the Boone County health department is working with university health officials to determine whether other students and staff need testing.

Privacy laws prohibit the release of any information about the student.

The ill student left campus voluntarily.

Only students with active infections can spread the disease to other through close contact.

So far this year, six cases of active tuberculosis have been reported in Missouri.
