REGINA - A University of Regina student is being treated for tuberculosis and hundreds of his classmates may have to be tested for the highly contagious disease.

University officials started informing students, staff and faculty on Wednesday about the unidentified male student having the respiratory disease. Dr. Moira McKinnon, Saskatchewan's medical officer of health, says the student came to the province about three years ago.

She says he is now in isolation in hospital and his disease is infectious, but they don't yet know how infectious it is.

Dr. Vern Hoeppner of the University of Saskatchewan's tuberculosis control unit says there is a risk of catching the disease if people have breathed the same indoor air as the infected person.

The students in the same classes as the afflicted student are being offered screening for the disease.
