There must be a large reservoir of virus in the general population in order to facilitate so many transmissions.

One would think so, no? Or perhaps there is a specific environment the virus thrives in - say air plane airconditioners? In a way similar to Legionaire's?

Just a guess, based on so many stories involving recent air flights.

But I don't think there's been one confirmed case yet of transmission from one person to another on an aircraft.

It seems that the geographical nexus is more telling (in terms of infections) than the act of flying..
