One of the first two people to test positive for coronavirus in the UK is a student at the University of York.
The university said while the news will cause "concern and anxiety among our students, staff, and the wider community", the risk of infection is low.
A spokesman said the student is not believed to have come into contact with anyone on campus while they had symptoms.
The student and another member of their family are being treated at a specialist unit in Newcastle.
They had been staying at Staycity apartment-hotel in York and were taken to hospital on Wednesday evening.
Health chiefs confirmed on Friday that they had tested positive for the virus – which has killed 259 people in China.

The university has advised people concerned about their health in relation to the disease to call 111, and have also set up a call centre over the weekend.
The spokesman said: "Our immediate concerns are for the affected student and family, along with the health and continued wellbeing of our staff, students and visitors."

Meanwhile, 83 British nationals evacuated from Wuhan have spent their first night of two weeks in quarantine, having arrived at Arrowe Park Hospital in Wirral in a convoy of six coaches on Friday evening.
One of the people on the rescue flight – which also carried 27 non-UK nationals to Brize Norton RAF base in Oxfordshire – described the accommodation at the NHS staff accommodation block in Merseyside as "perfectly nice".
In a video blog from inside his room Matt Raw told the Guardian: "They've actually put a bag here containing various essentials that we might need - underwear and things that people might not have had time to pack.
"It's a perfectly nice room. We've got all the essentials that we need."
The evacuees have been supplied with food, and laundry facilities, and have access to the internet and a team of medical staff who will closely monitor their conditions.
Kitchens are available for those who wish to self-cater, and families are being kept together, with games consoles, toys and cots provided.
Coaches which transported the evacuees were seen parked in a fenced-off area of the staff car park at the hospital on Saturday morning. It is understood they will be taken away to be decontaminated later.
In another development on Saturday the Foreign Office announced it is withdrawing some staff from China.
It said essential staff will remain to continue "critical work" but warned that its ability to provide help to Britons in the country may be "limited".
The British Consulate-General in Wuhan was also closed on Friday after the evacuation flight.
UK ministers have said the Government will send another plane to Wuhan to rescue British citizens if needed and the Foreign Office (FCO) is working with EU countries to add British passengers to any rescue flights they may charter back from the city.
One Briton in Wuhan has told of his fears of being left stranded after deciding he could not leave his wife behind.

Chris Hill, 38, from Sunderland said: "My wife is a nurse and is not able to get the time off and will not abandon her parents. I am not willing to leave her behind and take my daughter. It's either we all go or we all stay in Wuhan."
He added: "I had to make a choice which I did. My only worry now is after everybody pulls out the FCO will forget about those who are staying and not give any support for us."
He said the departure of embassy staff was "not a good sight to see really, is it?"
Some reports on social media raised concerns that Paddington station had been cordoned off on Friday night due to a suspected coronavirus case.

Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
