ACCRA (Reuters) - Staff with the World Health Organization battling an Ebola outbreak in West Africa see evidence that the numbers of reported cases and deaths "vastly underestimate the magnitude of the outbreak," the U.N. agency said on its website on Thursday.

The death toll from the world's worst outbreak of Ebola stood on Wednesday at 1,069 from 1,975 confirmed, probable and suspected cases, the agency said. The vast majority were in Guinea, Sierra Leone and Liberia while there have also been four deaths in Nigeria.
