A large study in the United States is looking at whether a test-and-treat approach should be supported by offering incentives to newly diagnosed people who attend medical services and maintain an undetectable viral load.
In sub-Saharan Africa, a number of studies are investigating whether providing incentives to adolescent girls who remain in education reduces their long-term HIV risk.
