Norovirus causes acute gastroenteritis (inflammation of the stomach and intestines). The most common symptoms are nausea, diarrhoea, vomiting, and stomach pain. The illness often begins suddenly and norovirus can make people feel extremely ill with frequent vomiting and diarrhoea. Most people get better within one to two days. Dehydration can be a problem among some people with norovirus infection, especially the very young, the elderly, and people with other illnesses.

Norovirus is highly contagious.
