A 21 year-old university student was found to have active TB in May 2009 during a house-to-house TB case finding survey based on chronic cough (=2 weeks). After consenting to participate, she reported a history of productive cough associated with chest pain for 3 months without hemoptysis. She also reported occasional fevers, loss of appetite, weight loss, and general body weakness for about one month. She had no history of any other chronic diseases and no history of smoking or drinking alcohol.
