Hundreds of Scot students are self-isolating after a suspected Covid-19 outbreak in university accommodation.
One positive case and a few suspected cases have been detected at Parker House in Dundee.
All 500 students living in the private halls of residence have been told to self-isolate until further contact tracing has been completed.
The single positive case attends Abertay University.
NHS Tayside chiefs confirmed the potential outbreak late on Tuesday night.
Dr Daniel Chandler, associate director of public health, said: "We know from outbreaks in other university settings across Scotland that the virus can spread very quickly in student accommodation.
"Therefore, as a precautionary measure, we are contacting all residents of Parker House and advising them to self-isolate immediately.
"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."
Professor Nigel Seaton, principal of Abertay University, said, "Our students in Parker House are being supported to self-isolate safely and we will remain in regular daily contact with them.
"The university already has enhanced cleaning and safety measures in place on campus, in line with national guidance, and the campus will remain open.
"We have contacted students and staff to remind them of their personal responsibilities in relation to Covid safety and to inform them of today's changes in Scottish Government guidance."
