Epidemiologists trace contacts by first interviewing the patient and then the family members to identify all possible names of the people the patient might have had contact with, Frieden said. Then, they will outline all the movements that could have taken place from the time the patient’s symptoms began until isolation.
A map will be made containing time, place and level of contact, shown in concentric circles to identify risk as high, medium, low.
The CDC team and other health officials will monitor all the contacts every day for 21 days. In Senegal, a single patient had more than 60 contacts and all were identified and none became ill, he said.
Frieden said that anyone with any likelihood of exposure from the Dallas case will be contacted.

Well, that's interesting. Then why did they quarantine the ambulance crew and take the ambulance out of service. Why aren't they releasing the airline and flight # that this guy flew in from? Did they take a poll of all the people flying on that airplane and ask if they were willing to fly with someone who could be infected with the Ebola virus and everyone voted yes?
