Ebola outbreak spreads to fourth West African country

An Ebola outbreak that has left more than 660 people dead across West Africa has spread to the continent’s most populous nation after a Liberian man with a high fever vomited aboard an airplane to Nigeria and then died there, officials said Friday. The 40-year-old man had recently lost his sister to Ebola in Liberia, health officials there said. It was not immediately clear how he managed to board a flight, but he was moved into an isolation ward upon arrival in Nigeria on Tuesday and died on Friday.

All ports of entry into Nigeria, including airports, seaports and land borders, are placed on red alert.
