MONROVIA, LIBERIA - AUGUST 16: A crowd enters the grounds of an Ebola isolation center in the West Point slum on August 16, 2014 in Monrovia, Liberia. A mob of several hundred people, chanting, 'No Ebola in West Point,' opened the gates and took out the patients, many saying that the Ebola epidemic is a hoax. The center, a closed primary school originally built by USAID, was being used by the Liberian Health Ministry to temporarily isolate people suspected of carrying the virus. Some 10 patients had 'escaped' the building the night before, according to a nurse, as the center had no medicine to treat them.
