The music sizzles through the stadium. The beat pulses across the pitch. In South Africa, United Against Malaria Champion Yvonne Chaka Chaka is fighting malaria through music, and the fans love it. The South African superstar performed her malaria anthem "Hearts on Fire" during the UAM celebration at the 2013 Orange Africa Cup of Nations closing ceremony in Johannesburg, together with African singers and dancers. The new song is available for purchase, with proceeds benefitting UAM and Princess of Africa Foundation.
