The Chairman of the Commission for HIV/AIDS and Governance in Africa (CHGA), Dr K.Y. Amoako, has opened a meeting of the Commission in Maputo, Mozambique, with a warning to Africa's governments that HIV/AIDS "poses the greatest threat to sustained economic development in Africa." "We have repeatedly stated that we are an activist Commission. It is time to go out and drive this message home to our governments and to those who can help us get it across," he told the meeting.
