Liberian man in Nigeria's Lagos being tested for Ebola

LAGOS (Reuters) - A Liberian man in his 40s is being tested for the deadly Ebola virus in Nigeria's commercial capital of Lagos, a megacity of 21 million people, the Lagos State Health Ministry said on Thursday. Ebola has killed 632 people across Guinea, Liberia and Sierra Leone since an outbreak began in February, straining a string of weak health systems despite international help. This would be the first recorded case of one of the world's deadliest diseases in Nigeria, Africa's biggest economy and most populous nation, with 170 million people and some of Africa's least adequate health infrastructure.
