An RAF aircraft has left Sierra Leone today carrying a British citizen infected with Ebola, bound for treatment in an isolation unit in London's Royal Free Hospital, reports the BBC. London is confirming that a male patient was indeed infected, notes the AP; he was a volunteer at a clinic in the nation's Kenema district, which has been especially hard hit by the outbreak. There have been upward of 300 infections in Kenema, about a third of all cases in Sierra Leone, which has recorded almost 400 deaths from Ebola. The British patient, the nation's first, is "not currently seriously unwell," says a rep for the UK health department. (More Ebola stories.)
