NPR's Tony Cox speaks with CNN correspondent Charlayne Hunter-Gault, reporting from the network's Johannesberg, South Africa bureau, about the impact of the announcement by former president Nelson Mandela that his son has died of AIDS-related complications. South Africa is ravaged by AIDS, and the announcement could have a huge impact in a nation where families feel ostracized for admitting a family member is stricken with the immune system disease.
