Cases of the new strain of coronavirus in the UK are "highly likely", a Public Health England (PHE) boss has said.
However, most of those affected abroad by the virus were making a good recovery, Prof Paul Cosford, medical director at PHE, added.
So far 14 people have been tested in the UK, with nine people awaiting results and five getting the all clear.
Globally,
there are more than 800 confirmed cases of the virus, which has killed 26 people in China.
All the people who have been tested in the UK had visited Wuhan - the Chinese city where the virus first broke out - in the last 14 days.
In Scotland, where five people were tested,
an incident team has been set up to deal with the health threat. Four of the patients were believed to be Chinese, Downing Street said.
Those tested in the UK included
one person in Wales, who was given the all clear last week, and
one man in Belfast.
One of those cleared was British artist Michael Hope, 45, who
spent two days in quarantine this week after developing "a nasty cough" on returning to Newcastle from Wuhan.
