Aid groups in west Africa say they have enough money to fight the virus but need more people. The WHO estimates that 1,000 foreign medical workers and 20,000 locals are needed to man the 50 Ebola treatment units due to be rolled out across the three worst effected nations, but so far there are firm commitments from foreign teams for only 30 of the units. Manuel Fontaine, head of UNICEF in west Africa:
The big gap is still in human resources. Money is necessary. It is an expensive operation. But we need people.
