UK hospitals have been warned to prepare for cases of a fatal, mystery virus which is currently infecting people in China.
Dozens of people have been hospitalised by an unknown virus which has killed one person, and there are now fears it could spread across the globe.
The World Health Organisation (WHO) has told hospitals worldwide to prepare for cases outside China.
There have been 41 cases in Wuhan city since December, with one fatality.
One cases has now been detected in Thailand.
It was initially thought the virus had been caught by contact with animals, but the WHO now believes it may be contagious between humans.
The WHO has given guidance to hospitals across the world on how to contain the virus if cases are detected.
Dr Maria Van Kerkhove, acting head of WHO's emerging diseases unit, said: "This is something on our radar, it is possible, we need to prepare ourselves."
The first case was detected on December 31 last year.
The unknown virus causes cold-like symptoms including a runny nose, headache, cough, sore throat and a fever.
Possible cases have been detected in Hong Kong and Singapore.
WHO has ruled out the unknown virus being SARS, bird flu, MERS or adenovirus.
