（以下報道發(fā)表于8月11日）兩名在利比里亞感染了埃博拉的醫(yī)療援助人員在使用了仍處于試驗階段的抗埃博拉藥物后病情有所好轉(zhuǎn)。世界衛(wèi)生組織（WHO）現(xiàn)正在考慮是否允許這種未經(jīng)測試的藥物被廣泛使用。請聽 BBC 記者 Imogen Foulkes 的報道：

No one really knows if the drug given to two American aid workers really helped or whether now, back in the United States, they are improving simply because they're getting the best medical care money can buy.

The World Health Organisation's discussions on whether to support further use of the experimental drug will be difficult.

Deciding against risks the accusation that a potentially life-saving treatment is available only to aid workers from wealthy countries.

Deciding in favour might, if the drug were to have major side effects, lead to charges the world's top public health body approved harmful medical experiments on some of the world's poorest people.
