The Florida Department of Health in Pinellas County confirmed Friday it is investigating a suspect case of tuberculosis.

The case involves a 17-year-old student at a Pinellas County School, the agency noted in an email to media. Officials have not said what school the student attends. They are, however, testing those in close contact with the teen since the disease is transmitted through the air "when people who have an active TB infection cough, sneeze or transmit respiratory fluids," the email said.

Tuberculosis, or TB for short, is known for spreading slowly, so health officials plan additional tests in eight to 10 weeks.
