Experimental Ebola drug sparks ethical controversy

The decision to use an experimental drug to treat two Americans infected with Ebola, while nearly 1,000 Africans have already died from the deadly epidemic, has sparked controversy — but US experts say it was ethically justified. The World Health Organization announced Wednesday it was convening a special meeting next week to explore using experimental drugs in the West African outbreak, after two health workers from the US charity Samaritan's Purse were treated with a drug called ZMapp. The experimental drug is still in an extremely early phase of development and had only been tested previously on monkeys. There is no proven treatment or cure for Ebola.
