Water-pipe Smoking as a Risk Factor for Transmitting Mycobacterium tuberculosis

A 20-year-old Swiss male presented at the emergency department with acute onset of febrile temperatures and hemoptysis and a 3-month history of productive cough. An X-ray and CT scan of the chest, sputum samples for acid-fast bacilli, polymerase chain reaction(PCR), and cultures for Mycobacteria revealed pulmonary infection with Mycobacterium tuberculosis. None of the classical risk factors for tuberculosis were present, but the patient reported regularly smoking a water pipe. Water-pipe smoking poses a serious risk of M. tuberculosis transmission. LEARNING POINTS: This case report illustrates an unusual risk factor for tuberculosis: water-pipe smoking. With the higher social acceptance of water-pipe smoking, physicians must be aware of the associated complications.
