Nigeria has confirmed 11 cases of Ebola, after a doctor who treated the Liberian man who brought the disease to Lagos fell ill, the health minister said on Thursday, according to Reuters. The doctor had been one of those involved in the initial treatment of Patrick Sawyer, who collapsed at Lagos airport on July 20, Health Minister Onyebuchi Chukwu told a news conference in the capital Abuja. A member of staff of West African regional economic body Ecowas this week became the third person in Nigeria to die of the disease, which has no proven cure and has killed more than 1,000 people across four West African countries. "Eight (others) are still alive, more than half of them are doing very well and actually showing signs of recovery ... under treatment," Chukwu said.
