Norovirus, also called the “winter vomiting bug”, is a stomach bug that causes vomiting and diarrhoea. It can be very unpleasant, but usually goes away in about two days.
Symptoms
The main symptoms of norovirus are:
- feeling sick (nausea)
- diarrhoea
- being sick (vomiting)
Other possible symptoms include:
- a high temperature of 38C or above
- a headache
- aching arms and legs
The symptoms start suddenly within one to two days of being infected.
Key treatment steps
You can usually treat yourself at home. Prioritize rest, drink plenty of fluids to prevent dehydration, and eat bland foods if you feel up to it.
There is no specific medicine for norovirus, but over-the-counter pain relievers like paracetamol can help with headaches and fever. Your doctor may suggest anti-diarrheal or anti-nausea medication.
You should start to feel better in a day or two. Stay off school or work until the symptoms have stopped for two days. Avoid visiting anyone in hospital during this time, as this is when you’re most infectious.
How norovirus is spread
Norovirus is highly contagious and spreads very easily and quickly.
You can catch norovirus from:
- close contact with someone with norovirus
- touching surfaces or objects that have the virus on them
- eating food that has been prepared or handled by someone with norovirus
Washing your hands frequently with soap and water is the best way to stop it from spreading.
