Bill Gates @ TED2009As you can see from the talk, the FOX news article is a bit off.
It was hardly a swarm of mosquitoes, just a couple in a small glass box. He did not say "There is no reason only poor people should be infected," but rather he said: "There is no reason only poor people should have the experience."
Finally he did not wait "a minute or so" to tell the audience they weren't infected, but after the cheering and applause died down, and that was roughly 20 seconds after he released them, he said they weren't infected.
It's kinda sad that FOX reported something trivial like this, completely bypassing the whole message of the talk. Why not write an article about the deaths caused by mosquitoes that *are* infected?
