I think it really depends on how viable the death is within the time of effect...
For instance 'airborne ebola' could mean that someone that has died of ebola or a vial containing ebola is made airborne (flung from a truck, falls out
of a plane, out a window) and the target get squished by the impact. Or the Band called 'Airborne Ebola' manage to kill the target within the time
period.
I saw no rule about the Death Note having to kill someone in a method that actually follows the intention of the person that wrote the kill notice in the book.
Only that the method is actually possible in the time period. So if there was a zombie apocalypse going on and you wrote death by zombies... they'd be
killed by zombies. If they could be pushed into a random, nearby, dimensional vortex and then land somewhere full of active zombies is more of a question.
