Secretary of State John Kerry has appointed Nancy Powell to be "Ebola Coordinator" for the State Department.

Powell, who resigned as U.S. Ambassador to India in March, will lead the Ebola Coordination Unit, State Department spokeswoman Jen Psaki said in a statement.

In her new role, Psaki said, Powell "will lead the State Department’s outreach to international partners, including foreign governments, to ensure a speedy and truly global response to this crisis."

Last week, saying "the world has a responsibility to act" to help contain the deadliest Ebola outbreak in history, President Obama announced that the United States will devote significant new resources to curbing the spread of the disease in West Africa.

“The reality is, this epidemic is going to get worse before it gets better," Obama said in announcing that the U.S. military will lead the fight against Ebola. "But right now the world still has an opportunity to save countless lives.”

Obama declared the epidemic a national security priority.

"Ambassador Powell, working with leaders from across our government, is leading our efforts to build the coalition required to bring this epidemic under control," Psaki said in the State Department's statement.

Powell previously served as the State Department's senior coordinator for avian influenza.
