The UK is to begin monitoring flights arriving from China, as part of a series of precautionary measures after the spread of a new coronavirus.
The measures, to be announced by the health secretary later , will apply to flights from Wuhan to London Heathrow.
Aircraft will land in an isolated part of Terminal 4, before being met by a health team, a government source said.
Public Health England has upgraded the risk from very low to low, the transport secretary said.
Chinese authorities have advised people to stop travel into and out of Wuhan , the city at the heart of the outbreak.
They also admitted the country is now at the “most critical stage” of prevention and control.
So far, there have been 440 confirmed cases and nine people have died.
Most cases have been in Wuhan and Chinese authorities believe the virus originated from a seafood market that “conducted illegal transactions of wild animals”.
However it has also spread to other Chinese cities and a handful of cases have been identified abroad, including in Japan and the US. There have been no cases in Britain.
