MONROVIA, LIBERIA - OCTOBER 13:  People walk past the Island Clinic Ebola treatment center on October 13, 2014 in Monrovia, Liberia. A planned strike was averted as most nurses and health care workers reported for work, many saying they could not in good conscience leave their patients unattended. Health workers have been asking for increased hazard pay. They are one of the most high-risk groups of Ebola infection, as nearly 100 of them have died in Liberia alone.
