JOHANNESBURG (AFP) - HIV infections among the world's youth dropped by 12 percent over the last decade, but fell short of the 25pc target set by world leaders, a UNICEF report said Wednesday. "Is it progress? Yes. Is it enough? Absolutely not," said Elhadj As Sy, UNICEF director for Africa. Five million people aged 15-24 have HIV, down 12 percent from 2001, but with 2,500 new infections daily, the report said. Young women are hardest hit, representing more than 60 percent of all young people living with HIV - a figure that jumps to 72 percent in sub-Saharan Africa. African youth generally bear a staggering share of the burden and risk: close to four of the five million young people living with HIV are in sub-Saharan Africa, it said.
