"The reality is this outbreak's not over," says Dr. William Fischer, speaking about Ebola. "It's just changed."
Fischer, a professor at the University of North Carolina who's been studying Ebola survivors, was speaking about the new cases in Liberia. On Monday, a 15-year-old died of the disease. The teenager's father and brother have also tested positive for Ebola. Health authorities have not yet determined how the family was infected.
Liberian health officials say the 15-year-old boy visited several clinics in Monrovia last week before finally being directed to an Ebola treatment unit.
