French medical organization Doctors Without Borders, also known as Médecins Sans Frontières, warns that the capability of its medical teams has reached its limit. Since the start of the outbreak in March, the organization has treated about 470 patients, with 215 confirmed cases. But without a deployment of resources from West African governments and other aid groups, MSF says it will no longer be able to send staff to new outbreak areas.

“The WHO, the affected countries and their neighboring countries must deploy the resources necessary for an epidemic of this scale,” says Bart Janssens, MSF’s director of operations, in a statement. “Ebola is no longer a public health issue limited to Guinea: It is affecting the whole of West Africa.”
