The world's "disastrously inadequate response" to West Africa's Ebola outbreak means many people are dying who could easily be saved, the head of the World Bank said Monday, as Nigeria confirmed another case of the highly contagious virus.

In a newspaper editorial, World Bank President Jim Yong Kim said Western health care facilities would easily be able to contain the disease, and he urged wealthy nations to share knowledge and resources to help African countries tackle it.

"The crisis we are watching unfold derives less from the virus itself and more from deadly and misinformed biases that have led to a disastrously inadequate response to the outbreak," Kim wrote in the Washington Post.
