title: [Investigations to be undertaken in case of tuberculosis-disease or recent tuberculosis-infection].
abstract: The objectives of the investigation are double. Not only must the sick patients be identified and treated to stop the transmission chain since they could be sources of infection, but recently infected patients must also be identified and offered treatment for tuberculosis-infection if necessary. The goal of this step is to prevent their infection from evolving rapidly to tuberculosis-disease. Moreover, in a community, it is necessary to evaluate the risk of transmission and to identify the possible factors favoring this transmission in order to set up preventive measures. When a case of tuberculosis-disease or infection is diagnosed, the risk of BK transmission and individual risk factors of the people living close to the detected patient must be assessed. When a case of recent tuberculosis-infection is diagnosed the source patient must be looked for.
