Health officials say there are no active cases of tuberculosis among students tested for exposure to the disease at the University of Saskatchewan, although many students have yet to be tested.

The university contacted 589 students who shared classes with a student who fell ill with the infectious disease.

The Saskatoon Health Region says 244 students were tested during a clinic held last week.

There is concern that some students may already have gone home for Christmas break. Health region plans to notify affected notify them so they can have the testing done in their home communities.

Another tuberculosis testing clinic will likely be held in January.
