Obama Urges World to do more in the Fight Against Ebola

President Barack Obama said Thursday that the Ebola outbreak was a growing threat to regional and global security and asked the world leaders to do more in containing the outbreak.

"More nations need to contribute critical assets and capabilities -- whether it's air transport, medical evacuation, health care workers, equipment or treatment," Obama told a meeting on Ebola on the sidelines of the U.N. General Assembly.

"If unchecked, this epidemic could kill hundreds of thousands of people in the coming months," he said, reports Reuters.

Obama said that the international response to the epidemic should be like a marathon run at the speed of a sprint race. He said that this will happen only if all nations and organizations play their role in the fight.

Doctors without Borders, the humanitarian aid organization, which has been in the forefront  in the fight against the Ebola appealed to the world leaders at the UN General assembly to take immediate action to contain the disease.

"Generous pledges of aid and unprecedented U.N. resolutions are very welcome. But they will mean little, unless they are translated into immediate action," Dr. Joanne Liu, international president of Doctors without Borders said, reports CNN.

"The reality on the ground today is this: The promised surge has not yet delivered. The sick are desperate, their families and caregivers are angry, and aid workers are exhausted. Maintaining quality of care is an extreme challenge," she said.

The U.S. Centers for Disease Control and Prevention (CDC) in a report published Tuesday, said that number of Ebola infections in Liberia and Sierra Leone could range between 550,000 and 1.4 million by January 2015.

Meanwhile, the Sierra Leone government has put three districts under indefinite quarantine, said President Ernest Bai Koroma.

The districts put under quanrantine are Port Loko and Bombali in the north and Moyamba in the south, Koroma said, reports AlJazeera.
