What is norovirus?
Norovirus is a very contagious virus that causes nausea, vomiting and diarrhoea. According to Cleveland Clinic, the symptoms may be similar to the stomach flu, but they have a different cause.
Norovirus spreads easily if a person comes in contact with someone who is has already been diagnosed with the virus. There isn't a vaccine for norovirus.
According to the Centres for Disease Control (CDC), norovirus causes stomach or intestine inflammation. This is known as acute gastroenteritis. Symptoms usually appear 12 to 48 hours after being exposed to the virus. Most people recover from norovirus illness within one to three days.
There is no particular medication to treat norovirus illness. To avoid dehydration, the CDC recommends drinking plenty of liquids to replace the lost fluid. It is also essential to wash your hands regularly with soap and water as the virus can stay in the faeces of recovered people for at least two weeks.
