This week was a big one for TeachAIDS, the Palo Alto-based non-profit that creates HIV prevention software that’s being used in more than 50 countries. On World AIDS Day it launched educational animations with characters and content specific to Botswana as founder Piya Sorcar (pictured left, with Lisa Ling) talked at TEDxWomen about the differences between awareness (knowing that the disease exists and kills) and knowledge (understanding ways to keep yourself from becoming infected). The organization has succeeded–and been culturally sensitive while doing so–where many large-scale campaigns haven’t: helping people get smart about their own health. Sorcar’s recent talk is well worth a look, and you’ll see why the work has received San Francisco AIDS Foundation kudos.
