Few people get a chance to speak directly with someone who’s seen the effects of Ebola in West Africa today. Students in the Earhart-Edison Exploration Academy at North Hall Middle School had a chance Wednesday to speak with Dr. Jennifer McQuiston, scientific adviser for public affairs for the Centers for Disease Control and Prevention. McQuiston spent October and November of last year in Sierra Leone, West Africa, where she aided in the CDC’s efforts to treat, control and prevent the spread of Ebola.
