A local nurse was on the front lines in the treatment of the two American aid workers who contracted Ebola and were brought back to the United States where they were cured after two weeks of tireless efforts.“Ebola has a very high mortality rate, anywhere from 80 to 90 percent,” said former McMinnville resident Dustin Hillis, who was assigned to the special infectious disease unit at Emory Hospital in Atlanta that handled the two Ebola cases.A 2003 graduate of Warren County High School, Hillis received his nursing degree from Georgia State University and took a nursing job with Emory shortly after graduation. His normal assignment is in neuro intensive care. However, upon news the two aid workers were being shipped here from Liberia for treatment, a rarely used special section of the hospital was opened to accept them.
