More than a dozen people in the UK have been tested for the new strain of coronavirus, Public Health England has said.
Five people have tested negative while nine others are waiting for results.
In Scotland, where five people were tested, an incident team has been set up to deal with the health threat.
Globally, there are more than 800 confirmed cases of the virus, which has killed 26 people in China. Authorities there are battling to contain it.
PHE’s announcement that 14 people in the UK had been tested came on Thursday night, but they did not give details of where the cases were.
Earlier, the Scottish government confirmed that five people had been tested. Four of them were believed to be Chinese, Downing Street said.
Meanwhile, one man was treated in Belfast for symptoms associated with coronavirus.
All the patients had been in Wuhan – the Chinese city where the virus first broke out – in the last 14 days.
Prime Minister Boris Johnson’s spokesman said the tests were “purely precautionary”.
