The infectious virus can strike at any time and typically lasts between one to three days, but for most people, it is most common to contract this virus from November to April.
You should call 111 if you have diarrhoea for more than a week or continue vomiting after two days, experience bleeding from your bottom, show signs of dehydration, or the patient is a baby under 12 months.
Symptoms appear very suddenly but usually only last for two to three days before the bug clears.
Norovirus cases have surged across the UK in the past fortnight, figures from the UK Health Security Agency (UKHSA) have revealed.
The easiest thing is to make sure you practise proper hand hygiene, especially after using public transportation, when using the bathroom, or before touching or preparing food.
