David Cameron has called for EU leaders to double their funding in the fight against Ebola to £800 million.
It comes after one of the doctors who discovered the virus, Professor Peter Piot, said the rest of Europe was not doing enough to tackle the epidemic.
Downing Street said the current total contribution from the EU was just £400 million.
Almost £300 million ($490m) will be ploughed into trying to contain the Ebola epidemic, the World Health Organisation has announced.
Some £296m will go towards trying to stop the spread of the virus over the next nine months, after projections suggested it could infect people in another 10 countries beyond the four currently affected - Guinea, Liberia, Sierra Leone, and Nigeria.
It comes after the UN health agency warned the disease could affect more than 20,000 people, with the estimated number of cases already thought to be up to three times higher than the known 3,069.
The current outbreak has killed more than 1,500 people in the West African countries.
