Norfolk and Norwich Hospital visitors warned of bug
The Norfolk and Norwich University Hospital has warned visitors that five wards are experiencing an outbreak of norovirus.
A blanket ban on visiting has not been enforced but only close family members should attend the affected areas.
Children under 12 years old are also not permitted on the wards, which are Docking, Elsing, Gunthorpe, Holt and Knapton.
The hospital said the virus circulates in the community at this time of year.
Dr Ngozi Elumogo, director of infection prevention and control at NNUH, said visitors should wash their hands with hot soapy water.
"Hand sanitisers and alcohol gel will work against some bacteria and flu viruses but they will not protect you against norovirus," she said.
