NJ officials: Woman in isolation tests negative for Ebola

New Jersey health officials say a woman who arrived at Newark Liberty International Airport from West Africa has tested negative for Ebola in a preliminary test.

The New Jersey Department of Health says the woman remains under observation and in isolation at University Hospital in Newark on Saturday. She is a health care worker who arrived Friday from West Africa, where she had contact with Ebola patients. She showed no symptoms of the virus upon arrival.

The woman became the first traveler quarantined under an Ebola watch in New Jersey and New York. She later developed a fever.

New Jersey Gov. Chris Christie and New York Gov. Andrew Cuomo earlier Friday announced a mandatory 21-day quarantine of medical workers and other airline passengers who have had contact with Ebola victims.
