ReviewWill DOTS do it? A reappraisal of tuberculosis control in countries with high rates of HIV infection.
In 1993 the WHO declared tuberculosis a global emergency, and subsequently introduced the DOTS strategy, a technical and management package based on earlier work of the IUATLD and international experience with directly observed therapy. Despite successful implementation of most of the elements of this strategy in several African countries and settings, tuberculosis case rates continue to escalate where the prevalence of HIV infection is high. We explore possible reasons for the failure to control tuberculosis even in the context of tuberculosis programmes that have been considered models for others to emulate. ⋯ Strategies for tuberculosis control programmes in countries of high and low HIV prevalence cannot be the same, but must take into account the epidemiology of HIV infection. HIV/AIDS in Africa poses severe challenges of purpose and identity to tuberculosis control programmes, which have not adapted to the altered realities of the HIV/AIDS era. DOTS alone is unlikely to control tuberculosis in sub-Saharan Africa; one major achievement of DOTS when implemented, however, has been its apparent ability to limit the development and spread of drug resistance.
