Health officials say a third Salisbury University student has been diagnosed with tuberculosis.

The Wicomico County Health Department and the university are working to test others at the school.

It is the third case to be diagnosed at the Maryland university in recent months. One student was diagnosed in October and a second was diagnosed last month. Officials say the latest student to be diagnosed is under medical care and is no longer attending classes.

Officials are asking anyone who may have been in close contact with the student to get tested.

Physician Deputy Health Officer Dr. James Cockey says testing will show whether the cases are linked. He says the county averages two or three cases each year, so it's unusual to have three in such a short time.
