Thirumurthy shared new research conducted in Kenya on important HIV prevention topics, which he undertook with co-authors from UNC-Chapel Hill and the Impact Research and Development Organization in Kisumu, Kenya.

His first presentation explored the possibilities of HIV self-testing, an innovative technology that is receiving attention in the wider HIV prevention community.

The study, titled “Acceptability and feasibility of a novel approach to promote HIV testing in sexual and social networks using HIV self-tests,” found that providing multiple HIV self-tests to women in populations with high HIV incidence in Kenya was a successful way to promote HIV testing among the women’s partners. In Kenya and other countries in sub-Saharan Africa, men in particular have low utilization of HIV testing.

A high proportion of women participating in the study reported giving self-tests to their sexual partners and others in their social networks, and the strategy also led to the identification of a significant number of HIV-infected adults.

Thirumurthy’s second presentation addressed economic incentives for a proven biomedical HIV prevention intervention — medical male circumcision.

A study titled “The effect of conditional economic compensation and lottery-based rewards on uptake of medical male circumcision in Kenya: a randomized trial” concluded that providing compensation in the form of food vouchers to those seeking circumcision services was effective in increasing circumcision uptake among men over a short time period.

Small economic incentives ($12.50 USD) successfully addressed barriers such as time and transportation costs, especially among men who were already contemplating circumcision. Lottery-based rewards with high-value prizes, however, did not significantly increase circumcision uptake.
