The NHS lists the main symptoms of norovirus as:

What should you do if you get norovirus

Unfortunately there isn’t a cure for norovirus. But treatments focus on alleviating symptoms, which should go away in one to three days. 

Dr Babak recommended staying hydrated and drinking plenty of liquids that include electrolytes, in order to help replace fluids lost from diarrhoea and avoid dehydration.

He also advised: "Infants, the elderly and those with other health conditions may require additional medical attention due to the risk of dehydration linked to norovirus." 

Taking paracetamol can help treat any aches, pains and fever.

And make sure you get plenty of rest in order to help your body fully recover.

What are the signs a norovirus infection is serious?

Norovirus can become serious, especially in vulnerable people.

As well as being at risk of dehydration, young children, older adults, and pregnant people may have weakened immune systems, making it more difficult for them to fight the virus.
