Marion County, Fla., health officials have encouraged 12 people to take preventative treatment after they tested positive for TB exposure. The individuals had been in close contact with a North Marion High School student in Citra, Fla., who tested positive for TB in July. Officials said the 12 did not have active TB nor were they contagious; however, they could develop active TB if not treated. TB is an infectious disease that usually affects the lungs but also can affect other organs and can be terminal if untreated. Symptoms include unexplained weight loss, fatigue, a persistent cough, night sweats, shortness of breath, and/or chest pain or tightness.
