Abstract
Tuberculosis is a contagious disease which propagates by air. It is connected to poverty and affects especially productive young adults in developing countries. In 2009, Tuberculosis caused 1.7 million deaths. It is among the most three causes of death in women between 15 to 44 years old. The evaluation was based on the surveillance criteria of CDC / Atlanta. Informations were collected on a form for the period from 2008 to 2011. Health workers were interviewed using a questionnaire. We used excel software for analysis. On a total of 36 investigated health workers, 21 (58%) need less than 10 minutes to fill the notification form, 29 (80%) accept the surveillance as their daily work with 28 956 filled items on a total of 29 384; 88% (32/36) of reports are verified by another person. A place is planned for monitoring of other diseases on all notification forms. From 56 513 made samples 10 201 are positive. The surveillance system worked continuously during all the period of the study. Twelve health facilities from 28 (42. 8%) send their reports. The routine tuberculosis surveillance system in the Lingwala heath District is flexible, acceptable, and useful with a positive predictive value of 18 % as well as 87.5 % of validity and a weak representativeness of 42.8 %. It is integrated but presents the risk of distortion and lack of informations. It requires a strengthening of resources and the integration of private health facilities.
