Rotavirus is a highly contagious virus and one of the common causes of severe vomiting and diarrhoea in babies and young children.
Although many children recover well, rotavirus can sometimes cause significant dehydration — especially in babies, who can become unwell very quickly.
What symptoms should parents look out for?
Rotavirus commonly causes:
* Frequent watery diarrhoea
* Vomiting
* Fever
* Abdominal cramps
* Poor feeding
* Tiredness or irritability
Watch for signs of dehydration.
Please seek medical attention if your child:
* Is drinking or feeding poorly
* Has significantly fewer wet nappies or is urinating less than usual
* Has a very dry mouth or no tears when crying
* Is unusually sleepy , lethargic
* Is vomiting continuously
* Has blood in the stool
Babies and young children can dehydrate surprisingly quickly.
Prevention matters:
Vaccination is one of the most effective ways to protect babies against severe rotavirus gastroenteritis. The rotavirus vaccine is given orally during early infancy and helps reduce the risk of severe illness and hospitalisation.
Good hand hygiene is also important, although rotavirus spreads extremely easily and can survive on surfaces for prolonged periods.
If your child has diarrhoea or vomiting:
The most important priority is maintaining hydration. Offer frequent small amounts of breast milk, formula or an appropriate oral rehydration solution.
A message from ProPaeds:
Most episodes of gastroenteritis are manageable, but parents should never hesitate to seek help when a baby or young child is not drinking, is vomiting repeatedly or appears dehydrated.
