OTTAWA -- A U.S. doctor who survived the Ebola virus says he'd like to eventually return to West Africa, the place where he got sick.

For now, Dr. Kent Brantly says his experience has given him a platform to raise awareness about the virus.

But he says he would like to return to medical work in Liberia at some point.

Brantly and a fellow aid worker were diagnosed with the illness while treating patients in Liberia.

He was treated with the experimental drug ZMapp and eventually discharged from an Atlanta hospital in August.

Brantly -- in Ottawa on behalf of the aid group Samaritan's Purse to talk about the group's use of recent federal funding -- is glad he received the drug, but says there needs to be a lot more data on its efficacy before it is approved.
