“Even a terrorist doesn’t function too well when debilitated by high fever, headache, vomiting and diarrhea.”
There’s an incubation period. You can even see for yourself:

Ebola is not contagious during the incubation period. It is only contagious once symptomatic, and becomes more contagious as the disease progresses. Even at its most contagious, it is only infectious through direct contact with viral-laden bodily fluids, and possibly with the bare skin of the patient.
Mr. Duncan was potentially contagious between Sept 24, when he first showed symptoms, and Sept 28, when he was finally admitted to the hospital. That is why the CDC and local public health officials worked to identify and assess all of Mr. Duncan’s contacts during that period, and are monitoring the high risk contacts now. It has now been 8 days since he was admitted to the hospital; the average incubation period of Ebola is 7-8 days, with a range from 3 to 21 days. There are 13 days left to monitor the contacts.
