"As Washington prepares to host the International AIDS Conference from July 22-27, PBS NewsHour will profile some of the parallel stories unfolding around the epidemic on opposite ends of the globe," the news service writes. In the first of these stories, the news service profiles two individuals -- John Johnson in Washington, D.C., and Alice Sibanda in Hwange, Zimbabwe -- who as children lost their parents to the HIV/AIDS epidemic. Noting Zimbabwe and Washington, D.C., are "8,000 miles apart and nearly as distant economically," the news service writes, "Both have some of the highest HIV/AIDS rates in the world" (Kane, 7/18).
