Rotavirus causes vomiting and diarrhoea usually in babies and young children. It can lead to severe dehydration which may result in death, if not treated. Immunisation is recommended at an early age to help protect against rotavirus.
Rotavirus is a virus that spreads very easily from person to person and is a common cause of severe diarrhoea and vomiting in babies and young children. Rotavirus disease is often more severe than other causes of diarrhoea because it is more likely to lead to dehydration (loss of body water), shock and sometimes death. Children can catch rotavirus several times in their lives. Generally, the first infection occurs between 3 and 36 months of age; and this first infection is usually the most severe.
The symptoms of rotavirus can start suddenly, one to three days after infection, and can range from mild (lasting only a couple of days) to severe (life-threatening). Vomiting is usually the first sign, followed by diarrhoea. Other symptoms may include fever and drowsiness.
A rotavirus infection is more likely to lead to dehydration and hospitalisation of babies and young children than other causes of diarrhoea. Some signs of dehydration which may need medical attention include dry mouth, not urinating much, few or no tears when crying and sunken eyes.
Symptoms generally disappear after 3 to 7 days.
This is not a full list of symptoms that can occur following rotavirus infection. Please speak to your doctor if you have any concerns about rotavirus.
Rotavirus can spread easily among infants and young children especially those in crèche or kindergarten.
The virus can be found in high concentrations in the faeces (stools) of an infected child and is spread via the faecal-oral route (swallowing of or contact with infected faecal particles). Examples of when this may occur include when you change a nappy or care for a sick child, have close contact with an infected person, come in contact with clothing, bedding or other things that an infected person has used or eat food or drink water that is contaminated.
Those who recover from rotavirus can remain infectious for up to two months.
Rigorous and careful handwashing and disinfecting of baby change tables and toys is very important to help reduce the risk of spreading the disease.
Please speak to your doctor if you are concerned about your baby’s risk of catching rotavirus.
Rotavirus can affect anyone, but babies and young children are most at risk of serious disease. Adults, especially those with a weakened immune system can also be infected with rotavirus.
Some groups of people are at increased risk of severe or life-threatening symptoms.
- Aboriginal and Torres Strait Islander children
- Those with a weakened immune system
- Those who have had an organ transplant
- Those with existing gastrointestinal problems.
Other people may also be at risk of rotavirus infection. Please speak to your doctor about your individual circumstances.
The rotavirus vaccine is recommended and provided free for infants as part of the National Immunisation Program (NIP). This oral vaccine is taken by mouth, and usually given at 2 months and 4 months of age.
Once your baby reaches a certain age, the rotavirus vaccine cannot be given, therefore adhering to the NIP schedule is important. Please speak to your doctor to learn more.

Learn more about who should receive flu vaccination.
Vomiting and diarrhoea caused by rotavirus can lead to dehydration. The main treatment for rotavirus is aimed at preventing or minimising dehydration by drinking plenty of fluids and rest.
Mild dehydration can be relieved with rehydration drinks available from your pharmacy. Severe dehydration may require hospitalisation for treatment using intravenous fluids (directly into the vein).
If your baby develops severe diarrhoea and vomiting you should seek medical attention immediately.
For information about rotavirus immunisation contact your doctor.
Some side effects may be experienced following immunisation. Please discuss any side effects or concerns with your doctor.
