The winter vomiting bug is on the increase - it's risen by a staggering 40% in the past two decades and this year alone over 5% of the entire UK population will suffer from it.

The main symptom of Norovirus is the sudden onset of nausea and vomiting and there is no cure with sufferers advised to let it run its course. However, it's advised to rehydrate and keep fluid levels topped up in particular with the young and elderly who are more at risk.

Using rehydration drinks like Dioralyte are the recommended way to keep fluid levels up.
