Tuberculosis is an infectious disease caused by the bacterium Mycobacterium Tuberculosis. The bacterium usually causes an infection in the lungs, but it can also cause an infection of the bones or kidneys. You can contract tuberculosis if someone with tuberculosis coughs in your direction or talks to you nearby. You can only become infected if you immediately inhale the bacteria. Tuberculosis can only be transmitted if there is open TB (if the bacteria lives in the lungs).
In the Netherlands, the bacterium almost no longer occurs. Here, TB is diagnosed 759 times a year. Internationally, however, there are still many cases of tuberculosis. Tuberculosis is most prevalent in parts of Africa, Asia and Eastern Europe.
