A WHO statement on Wednesday said 932 patients had died of the disease in West Africa so far, with most of the latest fatalities³ reported in Liberia, where at least 282 have died of the virus.

 

Announcing a state of emergency for 90 days, President Sirleaf said in a statement that the government and people of Liberia required "extraordinary measures for the very survival of our state and for the protection of the lives of our people".

 

She said that "ignorance and poverty, as well as entrenched⁴（根深蒂固的） religious and cultural practices, continue to exacerbate⁵ the spread of the disease".
