A man critically-ill with Crimean-Congo Viral Haemorrhagic Fever (CCVHF) has been flown from Glasgow to London in a special RAF isolation plane.
The 38-year-old, who had been in Kabul, Afghanistan, was diagnosed hours after returning to Glasgow on Emirates flight EK027 from Dubai on Tuesday.
He was transferred from the city's specialist Brownlee unit to Royal Free Hospital in London on Friday morning.
Passengers who sat near the man have been contacted and have no symptoms.
NHS Greater Glasgow and Clyde (GGC) said medical staff would continue to follow up with passengers on the flight from Dubai.
The health authority said the risk to all other passengers was "extremely low" and advised anyone with concerns to contact NHS 24.
This is the first case of CCVHF in the UK. NHS GGC said the patient's transfer was "in line with the UK-wide protocol for the management of diseases of this severity and rarity".
The man was stabilised overnight before being moved in specialist isolation facilities by air with the support of the Scottish Ambulance Service and the RAF.
Public health consultant, Dr Syed Ahmed, who is coordinating the investigations into this case, said: "The risk of person-to-person transmission of Crimean Congo Viral Haemorrhagic Fever is extremely low as it can only be transmitted by direct contact with infected blood or body fluids.
"It is not a virus which is transmitted through the air. As such the risk to those who were in close contact with him is minimal. "We have already made contact with all the patient's close contacts and they are being followed-up appropriately.
"The decision to transfer the patient to the high security unit at the Royal Free was taken in line with the national protocol for the management of cases such as this."
