Nigerian authorities on Monday confirmed a second case of Ebola in Africa’s most populous country, an alarming setback as officials across the region battle to stop the spread of a disease that has killed more than 700 people. Also Monday, health authorities in Liberia ordered that all those who die from Ebola be cremated after communities opposed having the bodies buried nearby. Over the weekend, health authorities in the West African country encountered resistance while trying to bury 22 bodies in Johnsonville, outside the capital Monrovia. Military police helped restore order. In Nigeria, Health Minister Onyebuchi Chukwu said test samples are pending for three other people who had shown symptoms of Ebola, and that authorities are trying to trace and quarantine others. The confirmed second case in Nigeria is a doctor who had helped treat Patrick Sawyer, the Liberian-American man who died July 25 days after arriving in Nigeria from Liberia. More
