The Irving Health Department in Irving, Texas, performed free TB tests this week on approximately 100 students and teachers at Nimitz High School after a former student tested positive for TB last month. The infected teen was not currently attending the school, but officials believed the student might have exposed people last spring between March and May. TB is an airborne bacterium that can spread through coughing or sneezing but can be treated successfully if diagnosed early. Early testing was important because of the possibility that one could be infected without showing any symptoms. Classmates and teachers received a phone call informing them of the possible exposure. Those at risk would receive their tests results on Friday. “It’s quite possible that no one is going to have a positive test. It's quite possible that nobody has any symptoms, but as a precaution you want to take this step and follow all recommendations of the health department and be here for these kids,” said Lesley Weaver, a spokesperson for the Irving Independent School District.
