This is NOT the end of the world. As deadly as Ebola is, it's actually rather terrible at spreading itself.
1. It is only contagious via bodily fluid. The best pandemic virus are spread through the air. It's the most efficient way to get a whole plane full of people sick. You have no more chance of catching Ebola from sitting next to someone on a plane or a train than you would of catching Herpes. Not gonna happen.
Edited again: Some people are confused about "airborne". Yes, if someone with active Ebola coughs in your face, you can get Ebola that way and I suppose that for the 2 seconds it's in the air, it's "airborne". Ebola is not "airborne" in the sense that a cold or flu virus is airborne in that the virus can not hang around in the air waiting to infect people, it can't survive in air filters or on surfaces. A truly airborne virus can infect a whole room full of people with one person's cough. Ebola is not airborne.
The other tremendous disadvantage Ebola has is that it doesn't typically cause coughing or sneezing like a cold virus. It causes bleeding out of various unpleasant orifices. That's certainly very unpleasant, but doesn't spread the virus like a good cough or sneeze.
2. It is only infectious once you are showing symptoms. So even in the incubation period, the person carrying it can't spread it. And when the carrier starts showing symptoms, they're incapacitated within hours. This is a terrible way to spread disease. A really efficient pandemic virus would give the person the sniffles and slight headache for a week or so before taking them out so that the person will ride the train, go out to dinner, go to work, etc. Diseases don't spread well when the person is at home sick in bed while they're infectious.
3. The only reason Ebola has spread as much as it has is because it started out in ideal disease-spreading conditions - poor countries with poor medical care, among people who have little trust for their governing authorities, who generally aren't sufficiently educated to understand the importance of quarantine, and who have funeral rituals which involve touching the dead body. Ebola would never survive in the United States or any other first world country with good medical care and with the ability to quarantine as needed.
Edited to add:
Can Ebola be transmitted by mosquitoes? Nope. Mosquitoes aren't a natural host. Sure, mosquitoes can bite people who have Ebola, but the virus will die inside the mosquito. Same with ticks and other biting insects.
Will Ebola become airborne? Almost certainly not. The virus is incredibly delicate. Even if you just dry out a bloody rag contaminated with Ebola, the virus will die. And the virus hasn't mutated significantly since it was found in 1976, so the odds of it mutating to be able to survive in the air are pretty darn slim. Not to mention that Ebola doesn't cause coughing and sneezing, two of the best ways for an airborne virus to spread, even if it does become airborne on some off chance.
Ebola is not intelligent, folks. Is it dangerous? Sure. Is it deadly? Absolutely. Is it intelligent? NO. Nor is it malicious. Ebola is not plotting world domination any more than that cold that's going around your office. It's just a virus. And we know how to deal with it. The only reason its survived this long is that it's popped up in the best possible place for it to survive - a place with terrible healthcare and with poor sanitation. It will die out again and it won't take over the world.
Don't panic.
