Fewer people are dying from AIDS-related illnesses and being infected with the HIV virus than at any time in the last decade, but more progress is needed in prevention, testing and treatment, a report from the United Nations AIDS programme (UNAIDS) said. Fewer people are dying from AIDS-related illnesses, with the number of deaths declining to 1.7 million in 2011. New cases of HIV infections were 2.5 million, the lowest level since 2001, according to UNAIDS figures for the last decade.
