A United Nations driver in Sierra Leone has died of the Ebola virus, officials said Monday.

Edmond Bangura-Sesay was quarantined Oct. 14 with a suspected case of the Ebola virus as a precautionary measure after his wife exhibited Ebola symptoms, the U.N. Women Office said in a statement. His wife remains under the care of the Ebola Treatment Center and "we wish her a swift recovery," the statement said.

"The U.N. Medical team is conducting immediate and robust contact tracing in order to ensure that all people who came into contact with the staff member while he was symptomatic are assessed and quarantined," the statement said. "Our thoughts now are with the family and friends of our colleague Edmond."

Bangura-Sesay, who died Saturday, drove for the office since 2005.

The U.N. Women Office works with West African governments, other U.N. agencies, and governments and charities worldwide providing public awareness campaigns as well as training, data collection, and shelters for orphaned and abandoned children in the virus-ravaged region.

In Oslo, health worker Silje Lehne Michalsen was declared free of Ebola and discharged from Oslo University Hospital Ulleval. Michalsen was working in Sierra Leone until she was diagnosed with the Ebola virus two weeks ago. She had been flown back to Norway, hospitalized and isolated in the infection ward.

Last week, a 56-year-old U.N. worker who contracted the disease in Liberia died in a German hospital.
