Lowbury Lecture 2007: infection prevention and control strategies for tuberculosis in developing countries - lessons learnt from Africa.
The World Health Organization ranks South Africa among the top ten of high-burden countries for tuberculosis (TB). The Western Cape Province has the highest prevalence of TB in the country. Studies performed in healthcare facilities both at Tygerberg Hospital and from Kwa-Zulu Natal province indicate a significant risk for nosocomial transmission of tuberculosis. An audit of provision for infection prevention and control (IPC) programmes revealed that although there were adequate supplies of protective clothing, the greatest need was for training and understanding of IPC principles among healthcare workers. In establishing national IPC guidelines for TB in South Africa, it has become evident that most of these were derived from existing guidelines in developed countries. Though the principles were sound, the practices were not realistic for developing economies and generally not implemented in healthcare facilities. Factors that influence a robust TB management programme are poverty, concurrent human immunodeficiency virus infection, overcrowding, ignorance of the disease and a varied level of health service delivery. It is recommended that a foundation of sound knowledge should be established upon which best practices should be built within the framework of good IPC principles.
