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.
There are fears Ebola could have spread to the Democratic Republic of Congo after 10 people died from a disease with Ebola-like symptoms, local officials said.
The deceased, which included four health workers, lived in a remote part of the northern Equateur province of Boende. The country has now sent its health minister and a team of experts to the area to confirm if it is the deadly virus.
Michel Wangi, a spokesman for the governor' office, said: "An illness is spreading in Boende but we don't know the origin."
So far the disease has killed more than 1,200 people in Guinea, Liberia, Sierra Leone and Nigeria.
