Slide show: In Dar es Salaam, women living with HIV support each other

In The September-October 2010 cover article, "The Social Epidemic," readers meet Kulwa Amiri Mbunju, a resident of Mburahati, a neighborhood in Dar es Salaam, Tanzania, and Amina Kiloko, a community health worker who visits HIV-positive clients like Mbunju in their homes. In this neighborhood, Harvard School of Public Health lecturer Marc Mitchell tested a mobile device loaded with special software. The device enabled Kiloko to screen patients for symptoms of complications of their disease and to refer them to a doctor if necessary—improving the quality of care these patients receive. But this isn't just a story about healthcare delivery. A visit to Mburahati to meet some of Kiloko's clients revealed their moving personal stories and the friendships that had sprung up between them.
