Two prisoners are being tested for coronavirus in Oxfordshire.
The men are inmates at Bullingdon jail, near Bicester, and are being kept in isolation in their cells, with access also restricted to the wing of the complex where they are being held, Sky News can confirm.
The prison has capacity for 1,114 inmates - including those on remand, those who have been sentenced, and young adults aged 18 to 21 - and remains operational, with Public Health England on site helping to manage the situation.
As the two prisoners were being tested, the World Health Organisation (WHO) announced the new coronavirus will be called COVID-19.
WHO director general Tedros Adhanom Ghebreyesus said the first vaccine could be ready in 18 months "so we have to do everything today using available weapons to fight this virus".
There have been a number of other coronavirus developments, including:

Eight people in the UK have been confirmed as having coronavirus, with the last four testing positive on Monday.
They are linked to Hove businessman Steve Walsh, who is believed to be a "superspreader" after 11 people he stayed in a French chalet with contracted the virus after he was infected in Singapore.

Health Secretary Matt Hancock announced on Tuesday that the government is launching a capital fund to support any urgent work the NHS needs to carry out to prevent the virus spreading, such as isolation facilities.
He said the NHS has been working hard to contact trace anybody infected patients have been around, and said that was how five people in the UK and five others in France, linked to Mr Walsh, were found.
Professor Paul Cosford, emeritus medical director of Public Health England (PHE), said "contact tracing" run by PHE was "working very well".
He added: "I should say that the people who are of concern are those who have had very close contact with somebody with coronavirus - face-to-face contact or within a two-metre range for 15 minutes or more."
PHE is now working to trace about a dozen people who were in contact with two doctors, including a Brighton GP, who were among the four new cases announced on Monday.
