MONROVIA, Liberia — Liberian officials confirmed a second Ebola case on Wednesday in the same town where the disease was detected days earlier on the corpse of teenager, seven weeks after the country was declared Ebola-free. The infected person was moved to Monrovia, said deputy health minister Tolbert Nyenswah. Health minister Bernice Dahn said Liberia has paid hazard benefits to “99 percent” of people who worked in the Ebola treatment units in addition to their regular salaries. [...] Wednesday, workers exhumed the body of the 17-year-old male student whose infection, detected after his death, sparked fears of the return of Ebola to Liberia.
