Tuberculosis

The classic symptoms are a chronic cough with blood-tinged sputum, fever, night sweats, and weight loss. Infection of other organs causes a wide range of symptoms. Diagnosis relies on radiology, a tuberculin skin test, blood tests, as well as microscopic examination and microbiological culture of bodily fluids. Treatmen is difficult and requires long courses of multiple antibiotics. Contacts are also screened and treated if necessary. Antibiotic resistance is a growing problem in (extensively) multi-drug-resistant tuberculosis. Prevention relies on screening programs and vacination, usually with Bacilus Calmette-Guérin vaccine.
