The governors of New York and New Jersey announced Friday afternoon that anyone flying into John F. Kennedy or Newark Liberty International Airport after having direct contact with Ebola-infected patients in West Africa nations will be immediately quarantined for 21 days.

The move comes one day after Dr. Craig Spencer tested positive for the Ebola virus, becoming the first case in New York state. He is currently being treated at Bellevue Hospital in Manhattan.

News 12 spoke to a doctor from Bellevue's gynecology ward who said most of her patients canceled their appointments after learning about the Ebola case.

Spencer returned to the U.S. a week ago after treating Ebola victims in Guinea. In the week before he was hospitalized, Dr. Spencer rode the subway, took a cab, went bowling and ate at a restaurant.

Gov. Andrew Cuomo and New Jersey Gov. Chris Christie said that in light of the situation, both states are imposing stricter guidelines than those of the CDC, which recommends voluntary quarantines.

"We are no longer relying on the CDC's standards. There are now New York, New Jersey standards for this," said Gov. Christie.

Under the enhanced protocols, those who have not had direct contact will be heavily monitored by public health officials and, if necessary, quarantined.

New York and New Jersey will also be working with the CDC and Customs and Border Protection on keeping track of who comes into the two states.
