Via The Guardian, this appears to be confirmation: First case of ebola reported in Africa's most populous city Lagos. But note that WHO hasn't yet confirmed the test results, and I don't see an update yet on the website of the Lagos State Ministry of Health. Excerpt:
A man has died of ebola in Lagos, the first confirmed case of the highly contagious and deadly virus in Africa's most populous metropolis.
Patrick Sawyer, a 40-year-old Liberian civil servant, collapsed on arrival in Nigeria's main airport on Sunday, health officials said. His condition rapidly deteriorated before he died, said Abdulsalami Nasidi, project director at the Nigeria Centre for Disease Control, who attributed his death to ebola.
Officials at the World Health Organisation confirmed a sample from Nigeria was being tested for ebola, but did not confirm the results.
The death marks a new and alarming cross-border development in a disease that has spiralled into the world's biggest epidemic, spread across three west African countries. At least 660 people have died in Guinea, Liberia and Sierra Leone since ebola was first diagnosed in February.
