As Gastroenteritis can be highly infectious, it is important to take steps to prevent it spreading from your child to other children.
Even if you isolate your child, it may be possible for adults in your household to spread the infection to other children without realising it.

Rotavirus vaccine
In England, a new vaccine is available that protects children against rotavirus gastroenteritis.
It’s given as a liquid from a dropper straight into the baby’s mouth for them to swallow at two months and then again at three months of age.
Two possible side effects of the vaccine are diarrhoea and irritability. These are usually mild and should disappear with time.
The rotavirus vaccine will be given as part of the routine childhood vaccination schedule from July 2013.
