Amy Stokes uses the internet to connect South African teens affected by HIV/AIDS and poverty with volunteer mentors from around the world. Stokes is the founder of Infinite Family and spoke with CNN about the importance of her group's efforts in South Africa -- where nearly two million children have been orphaned by AIDS. CNN: How does HIV/AIDS affect a South African child? Amy Stokes: They will talk about being very happy as children and growing up with two parents until they were grade school level. And then they'll lose one of their parents. They will move where they can be in a community that helps support them and then they'll lose the other parent. Then they're moved into a home where it's an auntie running the house -- and they'll lose that aunt. And then they go to live with the gogo -- or a grandmother -- and before long, they're living with 10 other children in the same 20 square foot space. That gogo is spending all of her time just trying to feed everybody, much less being able to help them prepare for their future. CNN: How widespread is the problem? Stokes: Many of these communities have lost up to 40 percent of the young adults [from HIV/AIDS]. So the children ... are losing, not only love and nurturing, but ... the education of having a parent attend to them. They lack access to everything that would teach them what is needed to be successful. However, they are the most hopeful children you will ever meet. They are resilient, resourceful; they are joyful; they are very ambitious.
