A health care worker who was quarantined after arriving at Newark Liberty International Airport from West Africa is criticizing the Ebola protocol.

Kaci Hickox, a U.S. citizen from Texas, was among the first to face the new protocol imposed in New Jersey and New York, which mandates anyone treating Ebola patients must be quarantined upon returning to the U.S.

She tested negative for the disease at University Hospital in Newark, NJ.

Hickox returned to the U.S. Friday after doing relief work in Sierra Leone. While being screened by officials, she admitted that she did have contact with patients infected with Ebola while in West Africa.

Although she showed no symptoms of Ebola upon arrival at the airport, Hickox was placed under quarantine and later developed a fever. Despite testing negative for Ebola, officials say Hickox will continue to be monitored for 21 days.

In an article published Saturday in the "Dallas Morning News," Hickox said she is upset about the treatment she claims she received from health officials.

She said she arrived at Newark Liberty International Airport around 1 p.m. Friday and was left behind closed doors. After spending seven hours at the airport, she said she felt like a criminal being kept in the dark.

She says she is worried about how other health care workers will be treated at airports when they declare they have been fighting Ebola in West Africa.

Gov. Christie apologized for what he called an inconvenience and admitted the response is a work in progress.

University Hospital officials say Hickox is still under their care, but that they cannot comment any further.

The Centers for Disease Control and Prevention said that workers in West Africa, like Hickox, are heroes.
