Abstract
There is limited literature on programmatic challenges in the implementation of a treatment-as-prevention (TasP) strategy among human immunodeficiency virus (HIV) and drug-resistant tuberculosis (DR-TB) co-infected individuals in sub-Saharan Africa (SSA). This paper highlights specific programmatic challenges surrounding the implementation of this strategy among HIV and DR-TB co-infected populations in SSA. In SSA, limitations in administrative, human and financial resources and poor health infrastructure, as well as increased duration and complexity of providing long-term treatment for HIV individuals co-infected with DR-TB, pose substantial challenges to the implementation of a TasP strategy and warrant further investigation. A comprehensive approach must be devised to implement TasP strategy, with special attention paid to the sizable HIV and DR-TB co-infected populations. We suggest that evidence-informed and human rights–based guidelines for participant protection and strategies for programme delivery must be developed and tailored to maximise the benefits to those most at risk of developing HIV and DR-TB co-infection. Assessing regional circumstances is crucial, and TasP programmes in the region should be complemented by combined prevention strategies to achieve the intended goals.
