Health officials say the risk from a respiratory illness similar to the deadly Sars virus remains "very low" after new evidence suggested it can spread from person to person.
Worldwide, there have been 11 confirmed cases of the new strain of coronavirus - and five patients have died.
One man in the UK is thought to have caught the infection from his father.
However, Professor John Watson, head of the respiratory diseases department at the Health Protection Agency said the new strain was still not thought to be as infectious as the Sars virus.
