The WHO is accused of underestimating the impact of Ebola
Poor communication and incompetent staff meant the World Health Organization failed to react swiftly Ebola outbreak in Africa, reports say.
An internal document said those involved “failed to see some fairly plain writing on the wall”, according to the Associated Press.
Separately, sources close to the WHO told Bloomberg of multiple failures in the outbreak’s early stages.
In response, a senior official told the BBC time would come for an inquiry.
In the worst affected countries – Liberia, Guinea and Sierra Leone – the Ebola virus has now killed 4,546 people with cases of infection numbering 9,191, according to the latest WHO figures.
The reports have brought into focus the way the WHO dealt with the outbreak in the months after it received the first reports of Ebola cases in Guinea in March.
Medical charity Medecins Sans Frontieres (MSF) warned in April that the outbreak was out of control – something disputed by the WHO at the time.
