Ebola-Stricken Surgeon Arrives in Nebraska for Treatment

Dr. Martin Salia was infected while treating patients in Sierra Leone.

Salia, 44, is a permanent resident in the U.S. and married to a U.S. citizen.

Salia is reportedly "critically ill," but was stable enough for the lengthy flight to Omaha, University of Nebraska Medical Center officials said in a statement. He is "possibly sicker than the first patients successfully treated in the United States."

He was taken off the plane via a specially protected stretcher and transported to a waiting ambulance.

His wife, Isatu Salia, and their son planned to travel to Nebraska to be with him, the family told ABC News.
