Liberian officials faced an excruciating choice Thursday: deciding which handful of Ebola patients will receive an experimental drug that could prove life-saving, ineffective or even harmful, AP reported. ZMapp, the untested Ebola drug, arrived in the West African country late Wednesday. Assistant Health Minister Tolbert Nyenswah said three or four people would begin getting it Thursday. The government had previously said two doctors would receive the treatment, but it was unclear who else would. The Ebola outbreak that was first detected in March in Guinea and spread to Liberia, Sierra Leone and Nigeria has killed more than 1,060 of the 1,975 people sickened by it, according to the World Health Organization.
