A passenger aboard a United Airlines flight has been taken into testing at Hackensack University Medical Center in New Jersey as a precaution after experiencing Ebola-like symptoms.

A female passenger traveling from Brussels to Newark aboard United Airlines Flight 45 has been taken to the hospital in Bergen County for testing, according to NewJersey.comThe passenger, only identified as a health worker, vomited aboard the plane. She had originally been in Sierra Leone before traveling through the Belgian capital.

"Proper protocols are being followed and members of the public have no need to be alarmed," Alicia D'Alessandro, Bergen County Executive James Tedesco's spokesperson, said.

The plane arrived at Newark-Liberty Airport at 2:03 p.m. with 248 passengers and 14 crewmembers. CDC personnel boarded the plane before any passengers disembarked and interviewed the ill passenger.

United Airlines has not confirmed whether or not the woman has Ebola.

"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," United Airlines said in a statement.

The unnamed passenger did not have a fever when she was transported, a hospital official told NorthJersey.com.

Both CDC officials and hospital personnel reassure the public that all proper procedures were followed.

Dr. Joseph Feldman, the hospital's chairman of emergency services, said that the patient was being held overnight for evaluation "in an abundance of caution."

Hackensack University Medical Center and the University Hospital in Newark were designated as "assessment hospitals" to test for the virus for up to 96 hours. The only hospital assigned to treat patients is Robert Wood Johnson University Hospital in New Brunswick.

"This is something we had hoped to avoid, but Hackensack University Medical Center is one of the top medical facilities in the country and they are here to serve," Hackensack City Manager David Troast said. "My prayers are with the victim. ... Hopefully, it's just the flu."

Newark-Liberty International Airport is one of five airports around the country that can receive people from the West African countries stricken with Ebola. The other airports are John F. Kennedy International, Washington-Dulles, Atlanta-Hartsfield and Chicago-O'Hare.
