Liberia confirmed a second case of Ebola on Tuesday, a day after the first case since the virus was declared eliminated in May. The country was declared Ebola-free by the World Health Organization on May 9. Dr. Moses Massaquoi of Liberia's Ebola task force confirmed the second case, but did not provide details. The body of a 17-year-old boy was the first to test positive for the virus on Sunday after the country was declared Ebola-free. Massaquoi said more people are being tested, including those who had contact with the teenager.
