Ebola returns to Liberia — three new cases reported this week in the previously Ebola-free country. People are questioning whether Liberia was really free of the disease to begin with. Liberian health officials reported the death of a 17-year-old boy from Ebola on Sunday, and two other cases of Ebola in people who were with the boy when he died. Liberia is now monitoring more than 100 people who had contact with the boy who died, and this number is expected to increase.
