A woman has been diagnosed in the UK with Crimean-Congo haemorrhagic fever following travel to Central Asia, the UK Health Security Agency (UKHSA) said.

Crimean–Congo haemorrhagic fever is a viral disease usually transmitted by ticks and livestock animals in countries where the disease is endemic.

The woman was diagnosed at Cambridge University Hospitals NHS Foundation Trust and is receiving specialist care at the Royal Free Hospital in London.

Dr Susan Hopkins, chief medical adviser at the UKHSA, said the virus “does not spread easily between people and the overall risk to the public is very low”.

It is the third known case of the fever in the UK, with prior cases reported in 2012 and 2014, both of which did not spread.

According to the World Health Organisation, around 30% of patients die, usually in the second week of infection.

In patients who recover, improvement generally begins on the ninth or 10th day after the onset of illness.

Symptoms of the virus come on suddenly and include fever, muscle ache, dizziness, neck pain and stiffness, backache, headache, sore eyes and sensitivity to light.

People can also suffer nausea, vomiting, diarrhoea, abdominal pain and sore throat early on, followed by sharp mood swings and confusion.

Other signs include rash in the mouth and throat, fast heart rate and enlarged lymph nodes.

Dr Hopkins said the agency was working to contact people who have been in close contact with the woman to assess them and provide advice.

She added: “UKHSA and the NHS have well-established and robust infection control procedures for dealing with cases of imported infectious disease and these will be strictly followed.”

Dr Sir Michael Jacobs, consultant in infectious diseases at the Royal Free London, said: “The Royal Free Hospital is a specialist centre for treating patients with viral infections such as Crimean-Congo haemorrhagic fever.

“Our high-level isolation unit is run by an expert team of doctors, nurses, therapists and laboratory staff and is designed to ensure we can safely treat patients with these kind of infections.”

A type of tick known as Hyalomma tick is the main carrier of Crimean-Congo haemorrhagic fever.

These are not established in the UK and the virus has never been detected in the UK in a tick.

Anyone visiting areas where the ticks are found should take protection, the UKHSA said.

This includes avoiding areas where ticks are abundant at times when they are active, using tick repellents and checking clothing and skin carefully for ticks.

According to the European Centre for Disease Prevention and Control, the affected ticks are in North Africa and Asia and are also present in southern and eastern Europe, having been recorded in Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, France, Greece, Italy, Kosovo, the former Yugoslav Republic of Macedonia, Moldova, Montenegro, Portugal, Romania, Russia, Serbia, Spain and Ukraine.
