Two American nurses were declared cured of Ebola and one -- Dallas-based Nina Pham -- hugged President Barack Obama at the White House to prove it.
But the states of New York and New Jersey ordered mandatory quarantine for medics who had treated victims of the disease in West Africa.
Steps include mandatory quarantine 21 days of any individual who has had direct contact with an Ebola patient while in Guinea, Liberia or Sierra Leone, including medics who treated Ebola patients.
The new measures were ordered by state governors Andrew Cuomo and Chris Christie on Friday, the day after an American doctor tested positive for Ebola one week after returning from working in hard-hit Guinea.
