A nurse who had been treating Ebola victims in West Africa was traveling to Aroostook County.

According to ABC News, 33-year-old Kaci Hickox had been planning to fly to the Northern Maine Regional Airport in Presque Isle, and then travel on to Fort Kent. Although Hickox didn't make it to the County, she was quarantined as soon as she arrived at Newark Liberty International Airport. New Jersey is one of four states that have begun quarantining people returning from West Africa who had contact with Ebola patients.

Hickox was treating Ebola patients in Sierra Leone, but said that she was showing no symptoms and had tested negative for the virus. She said she planned to self-confine herself in Fort Kent to make sure she was healthy.

Ebola can only be transferred from direct contact with an infected person’s bodily fluids. It cannot be transferred through the air.

Hickox said she was being held in a tent-like structure at University Hospital in Newark. According to CNN, Hickox has hired an attorney who will be filing papers to try to get her out of confinement.

Earlier this month, a patient at Maine Medical Center was isolated after showing Ebola-like symptoms, but tests came back negative for the virus.
