President Barack Obama warns that the Ebola epidemic in West Africa was unprecedented and is "spiraling out of control". The high alert issued by the President was a call to action to fight this deadly outbreak which is a threat to hundreds of thousands of people.
Speaking as he unveiled a major new US initiative which will see 3,000 US military personnel deployed to West Africa to combat the growing health crisis, Obama said the outbreak was spreading "exponentially."
Advertisement"Here's the hard truth. In West Africa, Ebola is now an epidemic of the likes that we have not seen before," Obama said.
"It's spiraling out of control. It is getting worse. It's spreading faster and exponentially. Today, thousands of people in West Africa are infected. That number could rapidly grow to tens of thousands."
"And if the outbreak is not stopped now, we could be looking at hundreds of thousands of people infected with profound political and economic and security implications for all of us."
As well as the military deployment, the US will also set up a command and control center in the capital of Liberia, the hardest-hit country, build new treatment centers and train health workers.
The Ebola epidemic has killed more than 2,400 people in Guinea, Liberia, Nigeria and Sierra Leone this year.
The virus can fell its victims within days, causing severe fever and muscle pain, weakness, vomiting and diarrhea -- in some cases shutting down organs and causing unstoppable bleeding.
No licenced vaccine or treatment exists.
- Security Council action -
The United Nations Security Council is poised to adopt a resolution on Thursday exhorting countries to provide more field hospitals and urgent aid to the crisis-stricken region.
Likely passage of the resolution marks only the third time that the Security Council will vote on a public health crisis after resolutions on AIDS in 2000 and 2011.
"This has gone beyond health issues," UN Secretary General Ban Ki-moon said.
"It has gone to areas affecting social and economic situations. It may even affect political stability if not properly contained and treated."
The United Nations said nearly one billion dollars would be needed to beat back the worst-ever outbreak of the disease, which is on track to infect 20,000 people by the end of the year.
The world body has set a goal of stopping the spread of Ebola within six to nine months but aid agencies are complaining that help has been too slow.
Ban is planning a "high-level event" on the sidelines of the UN General Assembly next week to draw attention to the crisis.
UN humanitarian chief Valerie Amos told reporters in Geneva the Ebola crisis faced a "huge funding challenge."
The capacity of Guinea, Sierra Leone and Liberia to provide even the most basic necessities is "on the brink of collapse," she warned.
The United Nations said the response to the crisis would require $987.8 million (763 million euros), with about half needed for Liberia.
- World 'needs to do more' -
The World Bank meanwhile approved a $105 million grant, part of a $200 million pledge made in early August aimed at helping people cope with the economic impact of the crisis and strengthening public health systems.
"The world needs to do much, much more to respond to the Ebola crisis in these three countries," World Bank President Jim Yong Kim said in a statement.
The UN said if the international community and affected countries respond swiftly and energetically, transmission should begin to slow by the end of the year and halt by mid-2015.
"The level of surge we need to do is unprecedented. It is massive," the United Nations' Ebola coordinator David Nabarro told reporters.
China will send a 59-person mobile laboratory team from its Centre for Disease Control to Sierra Leone, including epidemiologists, clinicians and nurses -- bringing the number of Chinese medics in the country to 174, the WHO said.
The EU, Britain, France and Cuba have also pledged to send medical teams and other aid to the region.
But this is far from enough, warned Joanne Liu, head of the Doctors Without Borders (MSF) charity.
Noting that the known Ebola toll "represents only a fraction of the real number," she stressed that "the ground response remains totally and lethally inadequate."
"The window of opportunity to contain this outbreak is closing," she warned.
