Honestly, my perspective is that if you're concerned about your personal safety, drive more carefully next time you're in a car. It'll do much more for you than thinking about Ebola. So far the only contaminations that have occurred within the US are two healthcare professionals who treated a misdiagnosed patient. Similar cases of misdiagnosis are extraordinarily unlikely at the moment, with the current levels of awareness and the CDC running ongoing investigations. Future ones should be handled correctly.
America, despite the problems of its healthcare system, is not in the same situation as the countries in which outbreaks have occurred. The affected countries simply do not have the ability to treat these diseases, they have insufficient beds for the numbers of patients meaning that many infected are not being housed correctly resulting in further spreading.
Medical research is continuing on the disease and being fast-tracked because of the severity of the African outbreak. The vaccine has already been made by Glaxosmithkline, it's just currently being tested for approval but they're confident enough to have prepared large batches of it ready to be sent to Africa once it is approved.
You've had one incident with three people affected. There is an organization with 15,000 people and a 7 billion dollar budget currently taking care of the situation. I think you're going to be okay.
