Young Swahili speakers with internet access can now make use of an on-line game teaching them about HIV and AIDS. The interactive feature, called Ungefanyaje or What would you do? in Swahili, takes players through a series of scenarios requiring them to make choices about relationships that underscore the importance of HIV prevention and testing. Launched by the United Nations childrens agency UNICEF, it aims to raise awareness about the virus among young people, who are seen as key to stemming its spread. Of the estimated 2.3 million children under 15 living with HIV/AIDS, two million are in sub-Saharan Africa, according to the agency. The game can be accessed on line in English and Swahili at www.unicef.org/voy/explore/aids/explore_1360.html
