The United Nations says the cost of containing the Ebola outbreak in West Africa has skyrocketed to $1 billion. That's up from the $100 million the U.N. estimated it would need about one month ago, according to Dr. David Nabarro, a senior Ebola coordinator with the international body.
"Because of the way the outbreak is advancing, the level of surge we need to do is unprecedented, it is massive," he said.
The virus has killed 2,461 people this year and infected nearly 5,000. President Obama will today announce the deployment of 3,000 U.S. troops to offer aid amid the crisis.
