An atmosphere of "fear and anxiety" exists in Sierra Leone as the Ebola crisis gets worse, says Save the Children chief executive Justin Forsyth.
The Ebola crisis in west Africa is getting worse, the head of a leading charity says.
An atmosphere of "fear and anxiety" pervades the region, Save the Children chief executive Justin Forsyth said on a trip to Freetown in Sierra Leone.
"I think it's still getting worse. It's going to get even worse before we get on top of it. We are still behind the curve," he said.
"We are in this race against time. There is enormous fear and anxiety."
Forsyth said he did not leave the country feeling "despair" and reported that there are signs that aid is making a difference, and there is "more action on the ground".
He praised the "inspirational" efforts of staff risking their lives to help bring the crisis under control.
"Save the Children staff who have lost relatives and loved ones have come into work and carried on the fight against Ebola.
"The whole country is mobilising. The international staff who are coming - families back home are very worried. It is an amazingly brave and courageous thing to do. People are putting their lives on the line."
On Saturday the Disasters Emergency Committee said it has been "overwhelmed" by the "extraordinary generosity" of the British public after STG4 million ($A7.30 million) was donated in just two days to a campaign to help people affected by the Ebola crisis in west Africa.
The UK Government has pledged to match the first STG5 million given by the public and its STG4 million contribution brings the fund total to STG8 million since the campaign was launched on Thursday.
So far, almost 5,000 people have been killed by the virus and more than 13,000 have been infected, although experts say the real figures could be much higher.
