Tuberculosis, or TB, is an infectious bacterial disease caused by Mycobacterium tuberculosis, which most commonly affects the lungs. It is transmitted from person to person via droplets from the throat and lungs of people with the active respiratory disease. In healthy people, infection with M. tuberculosis often causes no symptoms, since the person's immune system acts to 'wall off' the bacteria. The symptoms of active TB of the lung are coughing, sometimes with sputum or blood, chest pains, weakness, weight loss, fever and night sweats. Tuberculosis is treatable with a six-month course of antibiotics.
As countries advance toward disease elimination, the need for sustained funding remains
Countries in the Americas are making progress toward the elimination of diseases such as malaria, pediatric HIV and congenital syphilis, and tuberculosis. But additional sustained investments—including support from the Global Fund to Fight AIDS, Tuberculosis and Malaria—are critical to allow countries to finish the job, experts said at a Sept. 30 briefing organized by the Pan American Health Organization/World Health Organization (PAHO/WHO).
