Lagos: The Nigerian city of Lagos has shut down and quarantined a hospital where a man died of Ebola, the first recorded case of the highly infectious disease in Africa's most populous country.

Patrick Sawyer, a consultant for the Liberian Finance Ministry aged in his 40s, collapsed on arrival at Lagos airport on July 20. He was put in isolation at the First Consultants Hospital in Obalende, one of the most crowded parts of a city that is home to 21 million people, and died on Friday.

"The private hospital was demobilised [evacuated] and the primary source of infection eliminated," said Lagos State Health Commissioner Jide Idris on Monday. "The decontamination process in all the affected areas has commenced."
