This time the call has come from the US ambassador to the United Nations, Samantha Power who is visiting Guinea, Sierra Leone and Liberia
Speaking in Guinea, Samantha Power made it clear Ebola could be defeated, as it has in the past, but only if there's a more concerted effort.
"Together we can beat this epidemic. We have beaten every Ebola epidemic in history and we will do so if we dramatically increase our involvement and our engagement.
"I want to say to the Guinean people on behalf of President Obama that we stand with you and we will be with you till the end, until we have ended this horrible epidemic in your country," she said.
The three West African countries are bearing the brunt of the worst outbreak of the hemorrhagic fever on record.
A small number of cases have also been reported in Mali, Nigeria, Senegal, Spain and the U.S.
Aid groups on the ground say more doctors, nurses and treatment centres are needed. They say Ebola patients are being turned away as there are not enough beds and are usually cared for at home, where they risk infecting more people.
The Vice President of the Australian Medical Association, Doctor Stephen Parnis says Australia should heed the US calls and send people to West Africa.
"If we want to keep this disease out of Australia, the best way is to control it at the source. And there are a lot of factors that influence Australian thinking about it but we have the expertise, we have the resources to deploy there," he told SBS.
"The Australian government needs to act on the requests that its international partners have been giving that we send support."
"$18 million thus far is a drop in the bucket and the AMA has been calling for weeks now on the Australian government to do its fair share as part of the international effort."
Federal Health Minister Peter Dutton has told the ABC the government is considering all options.
He's pointed to Australia's readiness to deploy medical personnel to nearby countries.
"We have a team of 20 in Darwin that we could dispatch to Port Moresby, for argument's sake, if there was a presentation or an outbreak there," he said.
"We're asked to assist by the PNG government so the regional response is something we've been working up as well if that happens. We are in a position to send those forces very quickly, that includes doctors and nurses but also field hospitals. We have an infrastructure of which we can be very proud."
