Gastroenteritis, also known as gastro, is a common infectious illness in children that is a very unpleasant experience for both parent and child. Severe cases of gastro are most often caused by Rotavirus. This virus is highly contagious and is spread by touching contaminated hands or faeces (poo). It can also survive on items such as toys, clothes and change mats for days, increasing the risk of it spreading.


Symptoms are typically seen within days of exposure and include the following: vomiting, fever, sudden watery diarrhoea, abdominal pain, dehydration, drowsiness, cough and runny nose.

The first time a child catches Rotavirus is usually the most severe. Most children do not need to be admitted to a hospital following infection. Keep a close eye on young babies as the sudden dehydration caused by the Rotavirus can be life threatening to them.


Usually, symptoms will last from 4-6 days.

There will initially be vomiting that lasts 2-3 days, followed by diarrhoea that can last for 3-8 days. Mild diarrhoea may persist for a couple of weeks afterward.
