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.
British personnel on board a Navy ship heading for west Africa will be banned from taking shore leave for three months under strict rules to stop the spread of the Ebola virus.
The RFA Argus is setting off from Cornwall for Sierra Leone later this week, with a crew of 350 including 80 medics and 80 Royal Marines.
Marines who leave the ship for operations in Sierra Leone will go through a decontamination process upon their return.
Captain David Eagles said: "No shore leave is unusual, it will be quite tough but I think people will understand. I think people are going to be quite busy.
Any personnel showing symptoms of the virus will be taken off the ship to a treatment centre before they can become infectious, Cpt Eagles added.
