The impact of HIV on tuberculosis control--towards concerted action.
The well-established international control strategy for tuberculosis is based upon passive case-finding of the most infectious cases followed by effective chemotherapy with sufficient support to ensure and record a successful outcome. However, no country with a severe HIV epidemic is successfully controlling tuberculosis. HIV exerts a double blow. Not only must the health service manage a greatly increased number of patients (as many as fourfold higher in many African settings) but each individual patient needs to be managed more effectively if the control programme is to have a similar impact on transmission as it did in the pre-HIV era. In this paper, we discuss some of the effects of increased burden and stigmatization. We consider the potential of preventive therapy to reduce the impact of HIV on tuberculosis control and describe a more integrated approach to both infections that is being piloted in several sites in Southern Africa.
