Regional health officials responded to an Ebola scare at Portland International Airport on Wednesday morning after receiving word of a sick passenger traveling from Africa.

But the passenger, a young child, was deemed healthy and allowed to leave.

The passenger entered the United States in Atlanta on a flight from Nigeria. The child threw up while en route to Atlanta and health officials there deemed the passenger healthy.

But the child again threw up between Atlanta and Portland, prompting local officials to receive notification about the sick passenger.

After landing in Portland, the medical director for emergency services in Multnomah County examined the child and determined the passenger was healthy and could leave.

The child reportedly ate too much junk food on the flights.

No Ebola test will be performed on the child, who did not have a fever. Nigeria is considered a level one country with no special travel precautions.

Here is the press release from Multnomah County:

No risk at Portland airport around child illness



A Portland child who was evaluated after vomiting on an incoming flight Wednesday morning is at no risk of having Ebola. Health officials say there is also no risk to other passengers. It is likely something the child ate that was behind the vomiting, which was evaluated in Atlanta and again in Portland.



As a precaution, the child, who had travelled from Lagos, Nigeria, was evaluated by emergency medical personnel in Atlanta early Wednesday and cleared for the Atlanta to Portland flight.



When Delta Flight 773 landed in Portland about 11:30 a.m., Multnomah County Emergency Services Medical Director Dr. Jonathan Jui met the family. He interviewed and re-evaluated the child at Portland International Airport. The child was cleared to go home.



Passengers were notified there was no cause for concern and a handful who wanted additional information were provided materials, Dr. Jui said.



Because of concerns around illness among passengers from overseas, international flights, Delta Airlines in-flight medical personnel conferred with the Centers for Disease Control and Prevention specialists based in Seattle during the Atlanta to Portland leg.



Officials confirmed the child and family had only traveled to Nigeria. According to the CDC, Nigeria is not considered a country at risk for Ebola. Nigeria had a case in late July, but spread of the disease was quickly controlled. All people who had come in contact with Ebola patients in Nigeria have completed their 21-day monitoring period and are no longer at risk.



In addition, Dr. Jui said the family had no other contacts of concern.



"The Health Department and the Port of Portland have a plan for managing communicable diseases on commercial flights and this went according to plan,'' said Dr. Paul Lewis, Tri-County Health Officer.



Ebola is spread through direct contact with body fluids of a sick person or the remains of someone who has died of Ebola, or exposure to objects such as needles that have been contaminated. The illness has an average 8-10 day incubation period (although it could be from 2 to 21 days), and therefore CDC recommends monitoring exposed people for symptoms a complete 21 days. People are not contagious before symptoms such as fever develop.
