A woman travelling from Sierra Leone was sent to check for Ebola by officials from the Centers for Disease Control after she vomited on a flight to Newark Liberty International Airport.
She was returning from West Africa, which is an Ebola epidemic and was taken to Hackensack University Medical Center.
Advertisement"Proper protocols are being followed and members of the public have no need to be alarmed," said the spokeswoman, Alicia D'Alessandro.
D'Alessandro would not say whether the woman was suspected of having contracted the virus. She said the State Police and the Department of Health had contacted the county office of emergency management.
CDC staffers were sent to board the flight to interview the woman before she or other passengers were allowed to leave the plane, officials said.
"After arriving at Newark Airport from Brussels, medical personnel met a United flight to assist an ill passenger on board. Passengers and crew will stay on the plane until the medical personnel clear the aircraft," the airline stated.
Newark Liberty is one of five airports nationwide that were designated in October as U.S. points of entry for all passengers originating in Sierra Leone, Liberia or Guinea, the West African nations hard hit by Ebola outbreaks last year. The others are John F. Kennedy International, Washington-Dulles, Atlanta-Hartsfield and Chicago-O'Hare.
