Norovirus, which causes diarrhoea and vomiting, is one of the most common stomach bugs in the UK. It’s also called the “winter vomiting bug” because it’s more common in winter, although you can catch it at any time of the year.
Norovirus can be very unpleasant but it usually clears up by itself in a few days.
You can normally look after yourself or your child at home. Find out more: NHS Choices
