The condition of one of the air travelers being evaluated at a hospital in Chicago has improved and has been moved out of isolation.
Two people arrived on separate flights at O'Hare Airport Tuesday from Liberia complaining of illness.
Officials decided against screening them for Ebola.
The Tribune reports that one of the passengers is an adult who reported nausea and diarrhea.
That person was diagnosed with Typhoid Fever in August, but had a normal temperature during a screening at the airport. That adult is at Rush University Medical Center.
Hospital spokesperson Nancy Di Fiore tells WGN, "The patient was assessed by the Rush core response team including senior infectious disease experts in consultation with experts from Chicago Department of Public Health, and the CDC. It was determined that it was not necessary to test the patient for Ebola."
The second passenger is a child, who became ill en route to O’Hare, reportedly vomiting one time.
Federal authorities screened the child and said there were no symptoms of Ebola, or known risk of exposure.
The child is in isolation at the University of Chicago, and his family is currently under quarantine.
The two passengers are not related and were not traveling together.
