A man being treated for Crimean-Congo haemorrhagic fever (CCHF) after returning to the UK from Afghanistan has died in hospital.

It was the first laboratory-confirmed case of CCHF in the UK, according to the Health Protection Agency (HPA). CCHF is especially common in east and west Africa and is fatal in about 30 percent of human cases.

The airline passengers who sat close to the man are undergoing daily health checks.

“Crimean-Congo haemorrhagic fever can be acquired from an infected patient only through direct contact with their blood or body fluids, therefore there is no risk to the general public,” the Royal Free London NHS Foundation Trust said.

The 38-year-old man was diagnosed when he returned to Glasgow from Kabul on Tuesday. He had flown into Scotland on a connecting flight from Dubai.

The man, who has not been named, was being treated in isolation at Gartnavel General Hospital’s Brownlee Centre, which specialises in infectious diseases.

He was flown from Scotland on Friday to a high-security infectious diseases unit at London’s Royal Free Hospital, which houses the national specialist centre for the management of patients with hazardous infections.
