CNN had coverage all day, with reports on the Aids quilt (See a video on this from CNN.com), an interview with Magic Johnson and more. Here's part of an article from CNN.com about the "46664" concert held in South Africa.
Surrounded by some of the biggest names in music, former South African President Nelson Mandela sounded another call to arms Saturday in the battle against HIV/AIDS.
Former South African President Nelson Mandela waves at the crowd in Johannesburg, South Africa, Saturday.
Using the prison number assigned to him during his 27 years behind bars during the apartheid era, Mandela hosted the fifth 46664 concert in Johannesburg.
It was the highlight of World AIDS Day, marked each year on December 1.
The events are aimed at raising awareness, remembering those who have died and pushing for a cure.
In following this year's concert theme "It's In Our Hands," Mandela and celebrities stressed that much of the success in overcoming the disease depends on people taking responsibility for their actions.
"If we are to stop the AIDS epidemic from expanding, we have to break the cycle of new HIV infections. All of us working together -- government, communities and civil society -- can make the difference," he said.
More than 33 million people worldwide have HIV -- the virus that can lead to AIDS -- according to the United Nations. Most of them are in sub-Saharan Africa. That number represents a drop, however, from 39 million in 2006, which is partly attributed to more accurate counts.
Officials in Kenya, Zimbabwe and the Ivory Coast also say greater awareness and better behavior have contributed to a drop in HIV cases.
More than 2 million people have died of AIDS this year -- including 330,000 children.
