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.
Workers charged with burying the bodies of Ebola victims in and around Sierra Leone's capital Freetown have gone on strike.
The action has been called over the alleged non-payment of a weekly risk allowance.
One of the workers, Tamba Nyandemoh, told Reuters: "We have decided to stop working until they pay us our weekly risk allowance."
The specialised teams who are striking say they bury between 17 and 35 bodies a week and wear protective clothing to remove and dispose of the corpses.
Sierra Leone's deputy health minister Madina Rahman said the burial teams have been paid through the end of September and were only awaiting payment for this week.
