BBC: Swine flu virus dropped from plane?

Just heard a BBC TV report that the "ground zero" of the recent swine flu outbreak had been pinpointed.

This implies that the virus was dropped into the area by plane -- something that several conspiracy theorists have suggested.

Is the BBC really confirming these rumours, or is it just another instance of journalists not understanding the meanings of words like "ground zero" and "epicentre"?

We're all gonna die! Swine flu is coming!

Are you worried about swine flu?

Or are you more worried about the media hype about it?
