TED Prize 2006 Larry Brilliant: My wish: Help me stop pandemics (script)
Summary
The key to eradicating smallpox was early detection and early response.   The speaker was working in a program that is to eradicate smallpox. Smallpox was an infectious disease caused by a virus. Its patients had many spots all over their body. Smallpox killed more people than all the wars in history. The worst thing was that people didn't report if they had a care of smallpox in their house. It's because they thought that it was the visitation of a deity but ideas wrong to bring strangers into their house when the deity was in the house. Vaccination wouldn't work, because next year, there'd be 21 million new babies. It's so many. For eradicating smallpox, you have to find every single case of it in the world at the same time. He and his friends went door to door with pictures. They showed every single house and said that in your house, there is a kid or a person who has this kind of symptom. They made over one billion hours call. This surveillance system, early detection and early response led to smallpox eradication. In the world, there is some possibility to infect with malaria, yellow fever, yaws, and polio. It failed against them.
Infectious diseases kill so many people. The horrible things should not exist, but it's getting worse because travel is getting so much better.
However, we knew that the key is early detection and early response. We build an early detection system that's freely available to anyone in the world. If in the system,
all languages can be used, all people can find a hidden pandemic and immediately contain it. His wish is to build the system to stop pandemic of horrible infectious diseases.
