[The World Health Organization and the control of tuberculosis].

A brief history of the tuberculosis control programme is described. The basic issues of the programme, like BCG vaccination and case-finding are analyzed and the role of the specific Expert Committee is pointed out. Special emphasis on the task of PAHO and the Chilean participation was considered very important. The relationship between tuberculosis and HIV infection and AIDS is underlined as an emergent and relevant aspect of the epidemiological situation of tuberculosis, a real problem in the future.
