A doctor who worked in West Africa with Ebola patients remains in an isolation unit in New York after testing positive for the virus.
He's the fourth person diagnosed with the disease in the US and the first in its largest city.
33 year old Craig Spencer, was placed in a quarantined unit at Bellevue Hospital yesterday, six days after returning from Guinea.
Three people who had close contact with Spencer were also quarantined for observation - officials say all of them are still healthy.
New York Governor Andrew Cuomo says the city has been preparing for a case and he says lessons have been learned from the experience in Dallas.
