NHS HIGHLAND wants people to wash their hands and wrap up warmly in order to stem the spread of norovirus.
Director of public health Professor Hugo van Woerden urged people to wash and dry hands before preparing food, eating or drinking.
Professor van Woerden said: ‘Norovirus is highly contagious and is easily spread. At this time of year people are much closer together physically, whether it be in crowded trains or buses with little ventilation, department stores bustling with shoppers or people partying.
‘This close contact with others greatly increases the chance of catching a virus such as norovirus. Hand hygiene is a very important way to prevent the spread of norovirus.
‘Washing hands often – and drying them on disposable paper towels or laundering hand towels regularly – can significantly reduce the chances of catching norovirus.’
NHS Highland advises that people who have had sickness and diarrhoea wait until they are 48 hours free of symptoms before visiting a relative or friend in hospital.
