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.
Border staff do not feel adequately prepared to deal with the possibility of people with Ebola coming to the UK and need more information about the threat, a union leader said.
Immigration Service Union general secretary Lucy Moreton said the union's members were very concerned and were not confident over what to do if they suspected someone of being sick.
She told BBC Radio 4's The World Tonight programme: "They serve on the front line; they are the first point of contact usually for people coming off an aircraft and the concern is what do they do if they're confronted with someone that doesn't appear well who appears at the border.
"There is no health facility at the border, there is no containment facility and until extremely recently there has been no guidance issued to staff at all as to what they should do."
