I did not say it couldn't, but at the moment there is no evidence to show that it is air borne in humans, so suggesting that people on the plane have contracted Ebola via the air recycling system is misleading and ramping up the concern levels without foundation.
If you or anyone else have links to reliable sources suggesting that Ebola Zaire is or is about to become airborne in humans right now, then please post them. Otherwise, this is just scaremongering without evidence to back it up.
If people are genuinely worried about stopping this virus from mutating to become airborne, then they should be lobbying their governments to support the affected countries in Western Africa to get this outbreak under control. Not with pledges and pretty speeches, but with action and adequate supplies.
China, Uganda, Italy, France and Cuba all have organisations and teams over there helping.
Even so, countries are running out of Personal Protective Equipment, do not have enough beds etc. This is a real global threat and we need to sort it out.
