Another US doctor infected with Ebola in Liberia

MONROVIA, Liberia — Another American doctor has been infected with the Ebola virus in Liberia, according to a missionary group.

Earlier in the day, a key international doctors group warned that the world is “losing the battle” against the virus and UN officials are implored all countries to step up their response by sending help to affected countries.

Doctors Without Borders President Joanne Liu said her organization is completely overwhelmed as it treats Ebola patients in four West African countries. She called on countries with biological disaster response capacity to respond with civilian and military medical personnel.


‘‘Six months into the worse Ebola epidemic in history, the world is losing the battle to contain it,’’ Liu said at a United Nations forum on the outbreak. ‘‘Ebola treatment centers are reduced to places where people go to die alone, where little more than palliative care is offered.’’

World Health Organization chief Margaret Chan said the United Nations is urgently scaling up its response and called on all countries to contribute to the effort. David Nabarro, who is coordinating the U.N.’s response to the Ebola crisis, said the UN is ‘‘bringing in as outside health workers as much as we can.’’
