Hospital bosses have agreed to reopen the majority of wards at Gloucestershire Royal Hospital following an outbreak of a diarrhoea and vomiting bug.
The hospital suspended visiting last Friday, after several wards were reported to be affected by the illness.
A spokesman for Gloucestershire Hospitals NHS Trust has confirmed that two wards - 8A and 3B - will reamin closed for the time being.
Director of nursing Maggie Arnold said: "This is a precautionary measure and good infection control practice to protect patients and to control the spread of the illness. I hope that families and friends will understand that we need to protect our vulnerable patients and that is why we are asking them not to visit for this short period."
