Incidence Assay Critical Path Working Group, 2011, More and better information to tackle HIV epidemics: towards improved HIV incidence assays., PLoS Med, Vol: 8

Timothy Hallett and colleagues from the Incidence Assay Critical Path Working Group argue that a quick, easy, valid, and precise method of estimating HIV incidence in populations is needed, and discuss several new technologies to address this need.

Hallett TB, Over M, 2010, How to Pay “Cash-on-Delivery” for HIV Infections Averted: Two Measurement Approaches and Ten Payout Functions - Working Paper 210, Center for Global Development: Working Paper

In contrast to current donor policy, which funds a recipient country’s national AIDS control program, this paper proposes a measurement strategy to enable a donor to reward a recipient country’s success at HIV prevention, irrespective of the inputs, activities, or who gets the credit. In accordance with the “cash-on delivery” model of foreign assistance, the objective is not to replace traditional input- or activity-oriented aid, but to complement it by enhancing the motivation for local actors and their partners (including the traditional bilateral and multilateral funding agencies and their agents) to achieve measurable reductions in the rate of new HIV infections. This paper proposes two approaches to measuring the number of HIV infections averted between a baseline survey and a follow-up survey and explores the properties of ten alternative “payout functions” which would link measured epidemic changes to the size of the reward to be paid.
