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.
Health workers battling the Ebola outbreak at a major state run treatment centre in Sierra Leone have gone on strike over pay and working conditions.
Ishmael Mehemoh, chief supervisor at the clinic in the city of Kenema, in the country's east said: "The workers decided to stop working because we have not been paid our allowances and we lack some tools."
He added that clothing to protect health workers being infected is inadequate and there is only one broken stretcher which is used to carry both patients and corpses.
More than 20 health workers have already died from Ebola at the Kenema health clinic after catching the highly contagious virus from the patients they are fighting to save.
