Edmond Bangura-Sesay, a driver for the local office of U.N Women, died on Saturday, the international body said in a statement. He had been placed on observation last Tuesday, after his spouse began showing symptoms. The spouse is still being treated, the statement read.
"The UN 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 organization said.
Bangura-Sesay had been driving for the U.N. since 2005.
