The Queen Elizabeth University Hospital has closed two wards to new patients due to a norovirus outbreak.
Two wards have been affected in the Langlands unit on the campus and have been shut as a precaution as NHS chiefs urge people suffering from diarrhoea or vomiting not to visit.
The health service said the virus has become "more prevalent" across the whole of Scotland over the last few weeks with an increase in cases at the hospital. They confirm all appropriate infection control measures are in place.
Dr Linda de Caestecker, NHSGGC’s Director of Public Health said: “Norovirus, sometimes known as the ‘winter vomiting bug’, is the most common stomach bug in the UK, affecting people of all ages.
“It is highly contagious and is transmitted by contact with contaminated surfaces, an infected person, or consumption of contaminated food or water.
“The symptoms of norovirus are very distinctive – people often report a sudden onset of nausea, followed by projectile vomiting and watery diarrhoea.
“Most people with norovirus will make a full recovery in 1-2 days. It is important to keep hydrated – especially children and the elderly.
“Good hand hygiene using soap and water is important to stop the spread of the virus.”
It comes after the Scottish Government announced an inquiry into two deaths linked to pigeon droppings at the Queen Elizabeth University Hospital (QEUH) and Royal Hospital For Children and Young People in Edinburgh.
A child and another patient died after picking up an infection related to pigeon excrement last year.
An HPS investigation report states the first child was infected in 2016, with a total of 25 cases found by September 2018 when the patients were moved out of the wards 2A/B and into the neighbouring Queen Elizabeth University Hospital (QEUH).
The investigation will determine how vital issues relating to ventilation and other key building systems occurred and what steps can be taken to prevent these being repeated in future projects.
