MONROVIA, Liberia (AP) — Liberia's president opened one of the country's largest Ebola treatment centers in Monrovia on Friday, remembering the days when "the dying, the sick, the dead who could not picked up on time" as officials hope the disease is on the decline in this West African country. Some believe it's a sign that the Ebola outbreak is finally on the wane in Liberia, but others believe Sirleaf's order that the bodies of Ebola victims in the capital be cremated has led to people with symptoms hiding at home, because cremation violates traditions. "MSF teams are looking into the reasons for this; a widespread aversion to the government's mandatory cremation policy, poor ambulance and referral systems, changes in behavior, and other factors may play a role," the aid group said. Assistant Health Minister Tolbert Nyenswah, who heads the government's Ebola response, told The Associated Press the JFK Ebola medical team and a team of Cuban doctors will be in charge of the new center, located in Congo Town in eastern Monrovia. The United States has promised up to 4,000 American troops for Liberia and is building 17 treatment centers and helping to train thousands of health care workers.
