Norovirus most recently caused alarm at Stevenage’s Lister Hospital, where cases of the virus led health workers to close down wards.
An East and North Hertfordshire NHS Trust spokesman told local newspaper the Comet there had been a steady increase of the virus in the region.
They said: “Over the past few days there has been an increase in the number of cases of norovirus in and around Stevenage.
“It is currently affecting a number of patients at Lister and, as a result, the hospital has temporarily closed some wards to visiting to help prevent further spread of this virus.”
