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.
More troops, funding and medical staff are urgently needed to prevent the Ebola outbreak becoming the "definitive humanitarian disaster of our generation", Oxfam has warned.
The UK-based charity said there was less than a two-month window to curb the spread of the deadly virus but there remained a "crippling shortfall" in military personnel to provide logistical support across west Africa.
The charity said it was "extremely rare" to call for military intervention but troops were "desperately needed" to build treatment centres, provide flights and offer engineering and logistical support.
Oxfam also called for European Union foreign ministers meeting in Brussels on Monday to follow the UK's lead in pledging £125m in response to the Ebola crisis.
