Health professionals in Scarborough and Ryedale are seeing a rise in the numbers of people with the winter vomiting bug and other seasonal illnesses.
While the numbers are not necessarily out of the ordinary, GPs and other clinicians say patients and their carers can help reduce the risk of winter infections being transmitted through good hygiene, regular hand-washing and ample hydration.
Harrogate and District NHS Foundation Trust's Infection, Prevention and Control Team said: "There has been a rise in the number of cases of diarrhoea and vomiting, influenza and chest infections in the community over the past few weeks.
"We would like to remind people they can help reduce the risk of infection through good hygiene and it's also important that people who are suffering with a winter illness maintain hydration levels to avoid getting more poorly."
