Hundreds of students in Dundee have been told to isolate after a suspected coronavirus outbreak in a halls of residence.
A single positive case and small number of other possible infections are being investigated linked to Parker House – a private accommodation block.
Dr Daniel Chandler, associate director of public health, said the virus can "spread very quickly in student accommodation".
He added: "Further investigation and contact tracing are continuing and we will review this advice in the coming days.
"It is really important that any residents who develop symptoms book a test as soon as possible."

The university had already increased cleaning and safety measures so the campus will remain open, he added.
It follows the announcement of tougher restrictions in Scotland as cases across the UK begin to spike for a second time.
From Wednesday, households are banned from mixing indoors.
Those living alone will be able to form extended households, while couples not living together, those who need childcare and tradespeople will be exempt.
