There's this pleasing mythology out there that the World Health Organization is like some international version of the Center for Disease Control, that it's staffed by scientists and doctors flying all over the world and racing against the clock to battle infectious diseases and - against all odds - find The Cure.
I mean, that's an actual subplot of Contagion, where an intrepid WHO scientist tracks down the disease origin in Hong Kong, goes to the remote Chinese village where all of the children are sick (the children!), is taken prisoner, and works heroically (if ultimately unsuccessfully) to get vaccines to the children (the children!).
This is a crock.
