| Summary: | This study is an extension of a prospective epidemiological study of TB disease and infection in adolescents in the Worcester and surrounding areas in the Western Cape carried out from 2005 to 2009, in which 6363 participants were enrolled from local public schools. In this follow-on study, a subset of adolescents who were identified to have converted their QFT status during the original study will be followed up and observed for the occurrence of active TB disease over a period of two years. A similar sized, random sample of participants identified to have a QFT status that remained negative throughout the original study will be used as the control group. |
