UNITED NATIONS, Sept 2 (Reuters) - The worst ever outbreak of the Ebola virus will not be halted unless wealthy nations dispatch specialized biological disaster response teams to West Africa to stop its spread, the head of medical charity Medecins Sans Frontieres said on Tuesday.
"Six months into the worst Ebola epidemic in history, the world is losing the battle to contain it," MSF President Joanne Liu said in a speech to United Nations member states. She said aid charities and West African governments did not have the capacity to stem the outbreak and needed intervention by foreign states. The organization is known in the United States as Doctors Without Borders.
The United Nations and its World Health Organization have also appealed for more global help to stop the deadly disease.
Deputy U.N. Secretary-General Jan Eliasson said an international response with more involvement of U.N. member states may be needed, and referenced operations after the 2004 Indian Ocean tsunami and the Haiti earthquake in 2010.
David Nabarro, senior U.N. coordinator for the outbreak, said more health workers and treatment beds were needed, along with food, money, equipment, materials, vehicles, training, information systems support and communications guidance.
"The way to deal with Ebola is well known; it's just a question of putting it into practice," Nabarro said. "The outbreak is advancing ahead of us, it's accelerating ahead, and we in our control efforts, collectively, are falling behind."
"Every country in the world needs to be thinking 'what can we do to help?' Because if we don't get on top of this outbreak as a global community then this could effect all of us in unexpected ways," he warned.
Governments and aid organizations are scrambling to contain the disease, which has killed more than 1,500 since early this year.
WHO director-general Margaret Chan said the outbreak was the largest, most severe and complex ever seen in the 40-year history of the disease.
"The outbreak will get worse before it gets better and it requires a well coordinated, big surge and huge scale up of outbreak response urgently," she told the U.N. briefing. "The whole world is responsible and accountable to bring the Ebola threat under control."

Frieden said on Tuesday that he expected the number of Ebola cases to accelerate in the next two weeks and urged governments to act now.
""We're likely to see significant increases in cases. Already we have widespread transmission Liberia. In Sierra Leone, we're seeing strong signs that that will happen in the near future," he said. (Writing by Daniel Flynn and Michelle Nichols; Editing by Bate Felix, Toni Reinhold)
