A missionary health worker has become the third American to be infected with Ebola while working in Liberia, the Christian organisation SIM USA has said.
Dr. Rick Sacra, 51, had been delivering babies and working with patients who were not known to have the deadly virus.
Sacra is receiving care within the missionary's isolated Ebola unit in Monrovia, the president of SIM USA said.
The bodies of two men lay in the streets of Monrovia for four days after they died of suspected Ebola, residents told Reuters news agency.
Both men had shown signs of having Ebola but frightened locals had refused to take them to hospital.
Information Minister Lewis Brown confirmed that the bodies had now been collected from the Liberian capital, but said they had only been on the streets for a few hours.

David Cameron has co-chaired a United Nations meeting in Liberia's capital Monrovia, to discuss what targets to bring in after the Millennium Development Goals in 2015.
At the meeting's closing press conference, he defended his commitment to spend 0.7% of the UK's GDP on overseas aid.
"I am proud of the fact that Britain has kept its promises", Cameron said. "We will achieve 0.7% of our gross national income in aid as promised. And I am proud to be the PM who has helped deliver that."
