One ward at the Victoria Infirmary and one ward at the Mansionhouse unit have today re-opened.
Six wards at the Victoria Infirmary and one ward at Stobhill Hospital are not admitting new patients due to diarrhoea and vomiting.
Twenty patients are currently showing symptoms and there are no symptomatic staff in the hospitals.
Wards routinely do not admit new patients as a precautionary measure when three or more patients display symptoms of diarrhoea and vomiting. The normal extra infection control precautions have been put in place.
Dr Syed Ahmed, Consultant in Public Health Medicine, NHS Greater Glasgow, said "The situation in Glasgow's hospitals is reflective of what is happening in the community which has also seen a rise in the number of cases of diarrhoea and vomiting.
"We are working closely with the Hospital Infection Control Team and will continue to monitor the situation."
The hospital's Infection Control Team will continue to meet over the weekend and a further update will be issued on Saturday 09 April 2005 at 1330 hours.
