Health officials say it’s likely more people will travel to the U.S. carrying Ebola. Georgetown University Medical Center infectious disease specialist Jesse L. Goodman:
I would expect that so long as there is such a widespread epidemic in Africa, that even with good screening at the airports, etc., it’s possible there will be additional cases. This is a global public health emergency, and I think this indicates that.
The man identified as the first Ebola patient in the U.S. was incubating the disease when he traveled from Liberia to Dallas on Sept. 19-20, but he showed no symptoms while he was traveling, so his fellow travelers are not at risk.
