WHO calls ethics meeting over experimental Ebola drug

The World Health Organisation said on Wednesday it was convening an ethics meeting next week to explore the use of experimental treatment in the Ebola outbreak in West Africa. The move comes after two health workers from the US charity Samaritan's Purse were treated with medication that the WHO said had never been tested and shown to be safe in people. "We are in an unusual situation in this outbreak. We have a disease with a high fatality rate without any proven treatment or vaccine," said Marie-Paule Kieny, assistant director-general of the UN health agency.
