LONDON (AFP) - A man has died of Crimean-Congo haemorrhagic fever after flying home to Scotland from Afghanistan, in Britain’s first case of the deadly disease, health officials said Saturday. Two passengers who sat close to the 38-year-old man on a plane are undergoing daily health checks, although they have not yet shown signs of the tick-borne tropical illness. The man was diagnosed within hours of arriving on Tuesday from Kabul on an Emirates airlines plane that went via Dubai and he was initially treated in hospital in Glasgow. But as his condition worsened he was transferred to the high-security infectious diseases unit at London’s Royal Free Hospital on Friday, reportedly on board a special Royal Air Force isolation plane.
