CONCORD, N.H. (AP) — The New Hampshire Department of Health and Human Services is investigating whether any other students or staff at a Concord elementary school have been exposed to tuberculosis after a student was diagnosed with the disease.

The student attends Dame School, where a public meeting for parents was scheduled for 5:30 p.m. Friday.

Public Health Director Jose Montero said Friday that tuberculosis is difficult to spread from one person to another and requires prolonged contact. He said in this case, it seems unlikely that anyone else was exposed.

Tuberculosis is caused by a bacterium that usually infects the lungs but can show up in any area of the body. It is treatable with medications. Tuberculosis is usually spread through coughing. Symptoms include coughing, night sweats, fever, and weight loss.
