Latest on Dallas Ebola patient

(CNN) – Of the nearly 50 people in Dallas being monitored for Ebola. none shows any signs of the disease according to CDC director Dr. Tom Frieden.

Those under observation all came into contact with Thomas Duncan, a Liberian national in a Dallas hospital, who last week became the first person diagnosed with the virus on U.S. soil.

It is nothing short of miraculous that Duncan's contacts seem to be okay, especially given how his case was mishandled from the start.

Still, the CDC continues to assure the public there is no need to panic, and the message seems to be working.

According to a new poll released by the Pew Research Center, most Americans aren't very worried about the Ebola threat, and a majority have faith that the U.S. government can prevent an outbreak.

CNN senior medical correspondent Elizabeth Cohen reports on the latest on Duncan's condition.
