Norovirus is very easily spread from one person to another.
The virus can survive outside the body, so hard surfaces, toys, plates, cutlery and other objects can become contaminated. Careful cleaning of surfaces and hand washing is important to stop the spread of norovirus.
If you are concerned about norovirus call Healthline on 0800 611 116 or see your doctor or practice nurse.
The faeces and vomit of people with norovirus are infectious.
Norovirus can be spread in many ways, including having food or drinks contaminated with norovirus and having contact with a person who has norovirus.
To help stop norovirus spreading, wash your hands thoroughly with soap and water or a hand-sanitising gel.
People with norovirus usually get sick within one to two days. Symptoms usually last for two days and can include feeling or being sick, diarrhoea, stomach cramps, headache, low-grade fever, chills and muscle aches.
There is no specific treatment or vaccination for norovirus. It is not treated with antibiotics because it is caused by a virus, not bacteria. Dehydration is the main cause of serious illness.
Stay away from school, early childhood centres or work, and don’t prepare or handle food until two days after the symptoms have gone away.
Auckland Regional Public Health Service provides information about how to manage norovirus and stop it spreading, in particular, where there are institutional outbreaks.
