Officials are trying to trace people who had close contact with two Chinese nationals diagnosed with the new strain of coronavirus in the UK.
Public Health England (PHE) said anyone who had close contact – defined as being within two metres of those infected for 15 minutes or more – will receive health advice.
The pair – who are related – were taken ill while staying at a hotel in York.
It comes as Britons evacuated from China begin two weeks in quarantine.
The new coronavirus has caused the deaths of 259 people so far – all in China.
Cases of the virus have reached nearly 12,000 in the country – with cases reported in 22 other countries.
Some 83 UK nationals and 27 others were flown into the UK on a chartered evacuation flight from the Chinese city of Wuhan, where the outbreak of the novel coronavirus began.
The UK nationals were taken by coach to Arrow Park Hospital on the Wirral and arrived on Friday evening.
They will spend 14 days in quarantine – but not solitary confinement – in an accommodation block at the site.
The coach company which transported the evacuees to the Wirral said health officials advised its drivers did not need to wear protective clothing for the journey.
Horseman Coaches said five drivers will nonetheless enter a two-week period of isolation at home as a precaution.
The vehicles used will also be subject to a “military-grade cleansing process”, the company added.
Search for contacts
Efforts to trace those who may have had close contact with the two Chinese nationals who tested positive for the virus in Britain are continuing.
The pair – whose diagnosis was announced on Friday morning – were staying at the Staycity apartment-hotel in York when medics were called.
After initially being taken to Castle Hill Hospital in Hull, they are now being treated at a specialist infectious diseases unit in Newcastle.
Professor Sharon Peacock, director of the National Infection Service at PHE, said: “Public Health England is contacting people who had close contact with the confirmed cases.
“Close contacts will be given health advice about symptoms and emergency contact details to use if they become unwell in the 14 days after contact with the confirmed cases.”
Prof Peacock previously said while staff were working to trace people who have been in contact with the pair, they do not currently have “any idea” of how high that number might be.
Staycity said that – after consultation with PHE – its York hotel would stay open and the apartment used by the two patients disinfected.
Who qualifies as a close contact?
Anyone who is within two metres of the infected person for 15 minutes.
Would the virus survive on a tissue?
Probably for 15 minutes, but it is unlikely to survive on surfaces, like door handles, for more than 24 hours.

On Thursday, the UK’s four chief medical officers raised the risk level of the illness from low to moderate and the World Health Organisation (WHO) declared an international public health emergency.
The United States declared a public health emergency on Friday night, with President Donald Trump signing an order which will temporarily bar entry for most foreign nationals who have travelled in China within the last 14 days.
Ministers said the government is prepared to send another plane to Wuhan to rescue British citizens if needed.
‘Relatively minor disease’
Prof Whitty said the specialist unit at the Newcastle hospital was experienced in treating people with infectious diseases and there was “a high chance people would get better”, based on current information.
“A lot of people will end up with a relatively minor disease,” he said.
Ian Jones, professor of virology at the University of Reading, said the possibility of further spread was “minimal” because the cases were caught early.
Virus experts said they were not surprised to see cases in the UK but there was no reason to panic.
The WHO declared the outbreak a global emergency on Thursday.
The mortality rate for the new strain of coronavirus is currently low, at 2% – less than Sars at 10% and Ebola at 70%, the chief medical officer says.
But the death rate could yet go up if more of those in hospital die, or down if it’s discovered there are many other people with mild symptoms.
