Tuberculosis, or TB, is a bacterial infection that primarily affects the lungs.

Symptoms of TB include persistent coughing, fever, night sweats, and weight loss.

Transmission of TB typically requires prolonged close contact with an infected person.

Students who did not receive the notice do not have to be concerned, the school said.

This comes after another tuberculosis case was confirmed at Waukegan High School two weeks ago.
