I didn't mean for it to be combative... This whole thing can be pretty terrifying if you let it get to you.
But, I'm about as worried that Ebola will mutate to become airborne (in the medical sense, not in the literal sense that coughing or sneezing sprays infectious droplets) as I am that it will become sentient, get elected president, and start a nuclear war with Russia. Both are conceivable in the most theoretical, "but, WHAT IF??" sense... But no human transmitted virus has done either in the past, and from a stochastics perspective... I'm not betting on either. But, I'm more of a Bayesian than a frequentist, so I wouldn't be so bold as to say either is absolutely impossible.
Ebola is plenty scary as it is. Some non-doctor idiot doesn't need to make it scarier just because he's working for the UN and coordinated earthquake and tsunami response efforts before.
