A norovirus outbreak has hit a care home, nursery and hospital in Cornwall.
Three wards at Royal Cornwall Hospital have been closed because of the virus, which causes vomiting and diarrhoea.
The BBC reported that up to 20 operations a day are being cancelled at the hospital because of the outbreak.
The hospital is now in “internal major incident” status.
Patients have been warned not to visit general practice unless symptoms persist for more than 24 hours.
A Kernow clinical commissioning group spokesman said: "Outbreaks of norovirus can cause major disruption to both community and hospital settings.
“Those with a planned hospital admission should inform the hospital in advance and those with symptoms should not visit anyone in a hospital or care home.”
