Etienne Ouamouno, father of Ebola patient zero, poses for a picture in Meliandou February 4, 2015. A charred kapok tree and around a dozen graves scattered amongst the mud brick houses of Meliandou are painful reminders of the toll Ebola has taken on this village in southeast Guinea. Scientists traced the source of the worst-ever outbreak of Ebola to two-year-old Emile Ouamouno, who they believe contracted the disease while playing near the tree, home to hundreds of bats that may have been hosting the deadly virus. Ouamouno lost his son Emile, his daughter and his pregnant wife to Ebola. For Ouamouno and thousands of others in the forest region of southeastern Guinea, once the breadbasket of the West African nation, the suffering has only deepened. Picture taken February 4, 2015.
