Health chiefs in Sheffield are urging city residents to stay at home if they develop the winter vomiting bug norovirus, to prevent the illness spreading.
The NHS is advising people suffering from symptoms including diarrhoea and vomiting to avoid passing on the highly-infectious virus to hospital patients and vulnerable individuals, such as the elderly.
Richard Oliver, joint clinical director of NHS Sheffield Clinical Commissioning Group, said: “Although the norovirus can be very unpleasant, the illness is generally short-lived and most people make a full recovery within a few days.
“The most important part of management is to maintain fluid intake. This is especially important for small children and adults with other chronic disease.
“Washing hands with soap and water is particularly important as a means of reducing spread. You can remain infectious for 48 hours after symptoms have settled, so children should be kept off school for 48 hours after their last symptoms for this reason.
“If symptoms worsen or persist for more than 48 hours, you can get additional advice from NHS 111 or from your GP.”
Visitors should also stay away from hospitals if they are displaying symptoms.
