Four wards are closed and two others restricted at Lincoln County Hospital following an outbreak of norovirus.
United Lincolnshire Hospitals Trust (ULHT) are advising people to not visit the hospital unless completely necessary.
It is hoped that the two restricted wards, MEAU and Dixon, will open soon, however the Burton, Navenby, Carlton Coleby and Waddington wards are expected to be closed until the end of the week.
The trust’s Infection and Prevention Control team are monitoring the situation closely.
Simon Evans Director of Operations at ULHT said: “Lincoln County Hospital has had to restrict admissions to a number of wards, because a number of patients have been experiencing symptoms of the vomiting bug, norovirus.
“The restricted admission to these wards is just a precaution to prevent further spread of the virus. There is still a lot of norovirus circulating in the community.
“Visitors to Lincoln, Pilgrim and Grantham hospitals are asked to only visit if absolutely necessary and not to visit if they have had diarrhoea and/or sickness in the last three days.
“Children under five years should not visit.
“Those who are visiting should regularly use the hand gel available on all ward entrances and around the ward, as well as clean their hands with soap and water before they leave the hospital, to prevent the spread of the virus.
“We are also asking visitors to not see more than one patient or move between wards.”
