“Malaria is spread by mosquitoes,” Gates said while opening a jar onstage at the Technology, Entertainment, Design Conference — a gathering known to attract technology kings, politicians, and Hollywood stars.

“I brought some. Here I’ll let them roam around. There is no reason only poor people should be infected.”

First reported on social networking site Twitter, Facebook’s Senior Platform Manager Dave Morin blogged, “Bill Gates just released mosquitos into the audience at TED.”

Gates then waited a minute or so before assuring the audience the freed insects were malaria-free.
