Infection Information Sheet - Rotavirus

Rotavirus Vaccination, 4 Months

Rotavirus is the most common cause of severe gastroenteritis (gastro) in infants and young children. Rotavirus is spread easily by hand-to-mouth contact with faeces from an infected person, by touching contaminated hands or objects, or through contaminated food or water.

The main symptoms of rotavirus infection are vomiting and watery diarrhoea, which can lead to dehydration, particularly in young children. Rotavirus is one of the major reasons young children are hospitalised for acute gastroenteritis. Children under 5 years of age had approximately 10 thousand rotavirus related hospitalisations each year in Australia prior to the introduction of rotavirus vaccines.

Children can be infected with rotavirus several times during their lives. The first infection, which generally occurs in babies aged 3 to 36 months, tends to cause severe diarrhoea and dehydration.

Vaccination is generally considered to be the best approach for protection from severe rotavirus gastroenteritis. Rotavirus vaccines are available on the government funded immunisation program for infants. Talk to your health care professional to find out more.
