Dr. Eilish Cleary said she does not believe she will be directly exposed to patients infected with the disease during her eight- to 10-week stint.
Cleary, who previously worked as a doctor in Sierra Leone, will instead take on a public health role as part of a team organized by the World Health Organization in a bid to contain the unprecedented outbreak and reduce the chances of it evolving.
"Now that I'm working more as a public health doctor, I have much more experience in communicable disease control and in emergency response," she said in an interview Thursday. "It felt like it was a good fit between what they needed and what I could offer."
Cleary will leave Sept. 15 for Lagos and could be deployed to other countries depending on the need.
She said accepting a degree of personal risk is part of being a health professional.
"We need to remember that showing compassion and helping others is actually a good thing and contributes in a large way to having a healthier world to live in," she said.
"I felt it was important to walk the talk. Even with the personal inconvenience, it's important to step up and do these things."
