Roanoke health department will be testing 150 people who officials say could be exposed to tuberculosis. The 150 people include students and employees at William Fleming High. Earlier this week, school officials say a student was diagnosed with an active case of tuberculosis. Permission slips and letters will be sent home and need to be signed by next Wednesday December 4. If the slips aren't signed and returned, it will delay testing for those individuals. Testing is set to take place next Friday December 6 at the high school and results will be analyzed the following Monday.
