ElleyMae, keep in mind that Duncan (traveling when infected) is not the equivalent of the person who infected a HCW in Africa. He was someone who had been exposed, though he supposedly didn't know he had been exposed to the disease. (I'm skeptical of that unverifiable claim, but that's what he said.) But when he boarded the plane, and when he got to the US, apparently he had no symptoms, which means he had no reason to believe he was sick, and wouldn't have tested positive even if he had been tested.
HCW's are considered a much higher risk, because there's no question they have been in the vicinity of the disease. That's why they are being quarantined.
As I understand it, others traveling from those countries are screened, questioned, and (unless something raises red flags) will be monitored just in case, but they are considered low risk and not put into quarantine. But it's possible that different areas are each setting their own rules, because it sounds like CT has a mandatory quarantine for everyone.
