The death toll from the Ebola virus outbreak in West Africa has reached 887, that's according to the World Health Organisation (WHO).

The organisation's director-general, Margaret Chan, said: "If the situation continues to deteriorate, the consequences can be catastrophic in terms of lost lives, but also severe socio-economic disruption and a high risk of spread to other countries. This outbreak is moving faster than our efforts to control it."

And now the World Bank has pledged up to $200m in emergency funding to help fight the virus in West Africa. The African Development Bank has promised about $60m.

The money will be go to Guinea, Liberia and Sierra Leone - the three West African countries most affected.

But how should the money be used? And what are the challenges of containing the spread of this epidemic?
