The diagnostic tool chosen is chest X-rays, practiced directly in the places where the homeless gather. The report is delivered in the following 10/15 days directly to the interested party. If the result is positive or doubtful, the person is accompanied to public health facilities specialized in the diagnosis and treatment of communicable diseases. In addition to diagnosis and accompaniment to the necessary treatment, the project also deals with the hygienic-sanitary training of the people most at risk and accompanies those who are not in compliance with health documentation during the procedures for accessing the services offered by the NHS. The project also mapped the aggregation centers for homeless people in the area, the services dedicated to this category of people by various bodies and collected and analyzed epidemiological data.
