Improved knowledge, better programmes and policies, effective treatment and other scientific developments have reduced levels of new HIV infections globally. Evidence shows that programmes that prevent HIV among sex workers and their clients are most successful when all aspects of vulnerability are addressed and when they are underpinned by policy that advances human rights. This is particularly important in the context of the introduction of antiretroviral-based HIV prevention, which could have harmful consequences if not well planned. ⋯ A high-priority aim should be to ensure that the law enables commercial sex to take place in the safest possible conditions. To achieve this, the meaningful involvement of sex workers at all levels of the response is crucial. However, although that has been recognized in theory, it has not been achieved in practice.

Virtually no African country provides HIV prevention services in sex work settings with an adequate scale and intensity. Uncertainty remains about the optimal set of interventions and mode of delivery. ⋯ There is sufficient evidence of effectiveness of targeted interventions with female sex workers in Africa to inform delivery of services for this population. With improved planning and political will, services - including peer interventions, condom promotion and STI screening - would act at multiple levels to reduce HIV exposure and transmission efficiency among sex workers. Initiatives are required to enhance access to HIV testing and ART for sex workers, using current CD4 thresholds, or possibly earlier for prevention. Services implemented at sufficient scale and intensity also serve as a platform for subsequent community mobilization and sex worker empowerment, and alleviate a major source of incident infection sustaining even generalized HIV epidemics. Ultimately, structural and legal changes that align public health and human rights are needed to ensure that sex workers on the continent are adequately protected from HIV.

The provision of HIV treatment and care in sub-Saharan Africa faces multiple challenges, including weak health systems and attrition of trained health workers. One potential response to overcome these challenges has been to engage community health workers (CHWs). ⋯ CHWs can clearly contribute to HIV services delivery and strengthen human resource capacity in sub-Saharan Africa. For their contribution to be sustained, CHWs need to be recognized, remunerated and integrated in wider health systems. Further research focusing on comparative costs of CHW interventions and successful models for mainstreaming CHWs into wider health systems is needed.

HIV RNA viral load (VL) has been shown to increase during opportunistic illnesses (OIs), suggesting active HIV replication in response to infection among patients not taking antiretroviral therapy (ART). We assessed the effects of OIs on HIV RNA VL and CD4+ T cell counts among patients on ART with initially suppressed VL. ⋯ NCT00119093.
