Nigeria confirmed Thursday the country’s first Ebola-related death outside Lagos, the country’s main international transit hub. The victim, an unnamed doctor who died in the southeastern oil city of Port Harcourt, marks Nigeria’s sixth Ebola death in a recent outbreak of the disease primarily affecting West Africa. He is believed to have been infected by a man linked to Nigeria’s first Ebola case, Patrick Sawyer, who died in Lagos shortly after arriving there from Liberia. The yet-unnamed doctor had died last Friday, but Nigerian Health Minister Onyebuchi Chukwu waited until Thursday to confirm the case, the BBC reports.
