Briton with Ebola arrives in London from Sierra Leone

A British nurse who contracted the Ebola virus in Sierra-Leone arrived in London by military plane on Sunday, the ministry of defense said.

The patient, who is not "seriously unwell" according to the Department of Health, is to be treated at an isolation unit at a London hospital.

The patient's bed will be sealed off with a tent with its own ventilation system. Only trained staff can enter the unit.

A spokesman for Sierra Leone's Ministry of Health, Yahya Tunis, said the man was a volunteer nurse working in Kenema in eastern Sierra Leone, one of the areas hardest hit by Ebola which has now been quarantined.
