The worker, who has not been identified, was the first to be quarantined under a new policy announced on Friday making this mandatory for anyone arriving at a New York City-area airport after working with Ebola patients in three West African countries. The worker continues to be under a mandatory 21-day quarantine, the department said in its statement. recommended reading Timeline of Ebola patient's steps in NYC last week Governors Andrew Cuomo and Chris Christie announced on Friday that all medical workers traveling from Ebola-affected countries to New York City-area airports will face a mandatory 21-day quarantine under new screening rules that exceed federal guidelines. State health officials will extensively interview all travelers arriving at John F. Kennedy International Airport and Newark Liberty International Airport from Guinea, Liberia and Sierra Leone, Cuomo said. Besides medical workers, anyone else who had direct contact with someone with the virus must also submit to a quarantine for 21 days, Cuomo said at a joint press conference with Christie. "It's too serious a situation to leave it to the honor system of compliance," Cuomo said. The policy change came a day after Dr. Craig Spencer, a 33-year-old New Yorker, was diagnosed with Ebola at Bellevue Hospital soon after returning from Guinea. Spencer had been working with Ebola patients in the hard-hit West African country for the humanitarian group Doctors Without Borders. "He's a doctor and even he didn't follow the guidelines for the quarantine, let's be honest," Cuomo said. It was not immediately clear if Spencer had ever been required to quarantine himself by any authority. recommended reading NYC Ebola patient stable; Mayor says 'there is no cause for alarm' Doctors Without Borders has said a quarantine is "neither warranted nor recommended" for its returning workers unless they show Ebola-like symptoms. Instead, it asks returning workers to watch for a tell-tale fever by recording their temperature twice a day, which Spencer had done, according to New York health officials. Ebola is transmitted by direct contact with the bodily fluids of a person sickened by the virus, and has an incubation period of up to 21 days. Cuomo said the Centers for Disease Control and Prevention was aware of the new screening procedures, and agreed that states have the right to protect their borders. CDC's guidelines may work elsewhere, he said, but were insufficient for the country's most densely populated metropolis. "You go out one, two or three times, you ride the subway, you ride the bus, you could affect hundreds and hundreds," Cuomo said. The CDC and Doctors Without Borders did not immediately respond to a request for comment. Christie said that people facing quarantine orders who live in New York or New Jersey will be able to be quarantined in their homes. Those from outside the area will be sent to some sort of medical facility, he said. By REUTERS Share on Facebook Share on Twitter Comments Comments section is temporarily on hold. Here’s why.
