The gastroenteritis CPG has been updated as a part of the suite of hydration CPGs covering IV fluids, dehydration, vomiting and gastroenteritis.

The Key points for the CPG are

1. In a child with red flag features or a child with vomiting without diarrhoea, consider alternative diagnoses
2. Most children do not require investigations, including stool testing
3. Whenever possible, the enteral route (oral or nasogastric) should be used for rehydration
