Balancing community mobilisation and measurement needs in the evaluation of targeted interventions for HIV prevention

摘要

The case that engaging communities at a high risk of HIV to act in reducing their own vulnerability is essential to prevention programmes has gained widespread acceptance as a public health principle. Producing unequivocal evidence of its effectiveness in reducing HIV transmission is problematic however and the means and mechanisms through which such effects may operate remain a matter of debate. The papers in this special issue contribute to our understanding of both these issues, while indicating that it is feasible to mobilise high risk, marginalised communities for HIV prevention on a large scale.
