Rotavirus is the most common cause of severe gastroenteritis in infants and young children in Australia.
Children can be infected with rotavirus several times during their lives, and almost every child will suffer at least one infection by the age of three years. It is easily spread from one child to the next. Symptoms range from mild, watery diarrhoea to severe, dehydrating diarrhoea with vomiting, fever, and shock.
Rotavirus infections are often more severe than other causes of diarrhoea. They are more likely to be associated with dehydration and require treatment in hospital. Confirmation of rotavirus infection can only be made by laboratory testing of faecal specimens.
In Australia, it is estimated in children less than five years of age that there are approximately 10,000 hospitalisations, 115,000 GP visits, 22,000 emergency department visits and one death due to rotavirus
each year.
