I actually live in Dallas now and work in healthcare on the business side of things. Doctors I talk to are all extremely worried about this. If you lived here and walked in hospitals all day like I do you would be paranoid. People that say you shouldn't be worried have no understanding of the disease, or are getting their facts strictly from the CDC or news articles that repeat the garbage coming from the CDC. I could speculate a lot on why they would be doing it but it's not as important as understanding how quickly it can spread. I hate CNN and everything they do, but they actually put out an article called "5 things the CDC got wrong about Ebola" that's fairly spot on.
The whole don't worry it's not contagious if you don't have symptoms crap is exactly why you should be worried. Think about this how many times have you gone to work with a low grade fever and took a Tylenol and pushed through it. The symptoms of Ebola set on slowly and at first are impossible to differentiate from other common viruses like the flu.
I'll lay out a very real hypothetical scenario for you: A healthcare worker comes into contact with a patient that has Ebola. She wears protective gear and the CDC tells her you don't have to worry, you are in the low risk group. Go about your normal life and just "self monitor" by taking your temperature twice a day. She takes her temp, it's 99.0 so no biggie, and go out to a bar and get drunk. She starts to run a fever which means you're contagious, but don't know it because you're hammered. She makes out with a random dude who is also drunk. The next afternoon when she wakes up she takes her temp and realizes that she has a fever and calls and reports it. That evening she finds out she is positive for Ebola. She starts going through everyone she contacted in the past 24 hours. Maybe she remembers the makeout, maybe not. Probably can't remember the dudes name. Impossible to figure out who it is. The information on who she is doesn't make it to the news for 3 days. In the meantime, the random dude starts to run a fever, takes a Tylenol and goes out and makes out with people. He doesn't know he's had contact with someone who has Ebola until he checks the news, or he might not see the news and not even be tested for it until possibly his symptoms worsen and the hospital has to screen for everything to see what it is. And think about all the people he had close contact with in the meantime.

With something this deadly you take no chances, and by downplaying this the government is encouraging people to take a lot of them.
