NSW public health alert

​People in NSW Australia are encouraged to stay on alert for symptoms of gastroenteritis, with testing and hospital data showing a significant rise in cases in recent weeks across the state.

The latest testing data shows rotavirus notifications are at some of their highest levels of the last decade. In the first two weeks of 2023, 197 cases of rotavirus were identified, compared with about 40 cases during the same period usually.

Rotavirus is one common cause of viral gastroenteritis and can be particularly severe in young children.

Read on to find out more about how you can prevent and treat gastroenteritis.


What is gastroenteritis?

Gastroenteritis, commonly called the 'stomach flu' or 'gastro', is a short-term infection that affects the digestive system. It can be triggered by a range of different causes, including viruses, bacteria, parasites, bacterial toxins, chemicals and certain medications.

You can get it from eating or drinking contaminated food or water or from viruses such as the rotavirus and norovirus. It can appear within one to three days after you're infected and symptoms can range from mild to severe. While symptoms usually last just a day or two, they can occasionally last for up to 14 days. Gastroenteritis is also highly contagious.

Signs and symptoms

Some common symptoms of gastroenteritis include:

  • Stomach cramps or pain

  • Nausea

  • Vomiting

  • Diarrhoea

  • Bloating

  • Low-grade fever

  • Loss of appetite

  • Lethargy and body aches.

    Rotavirus can be potentially deadly and mainly affects children 6 months to 3 years old. See a doctor if your child is less than 6 months old, has other health problems, is not taking enough fluid, keeps vomiting, is tired/drowsy, has blood or mucus in their poo, or has abdominal pain or high fever and isn’t getting better.

How to treat it?

Ways to treat gastroenteritis include:

  • Drinking lots of fluids to help prevent dehydration

  • Antibiotics, if bacteria are the cause

  • Rehydration fluids from a pharmacy

  • Eating small amounts of food often if you feel nauseous such as plain crackers or bread; avoiding fatty, spicy and oily foods which can upset the stomach even more

  • In severe cases, you may need to go to the hospital where you may be given intravenous fluids.

How to prevent it?

You can reduce the risk of infection by:

  • Staying at home while you're sick, until 48 hours after symptoms have stopped.

  • Wash your hands with soap and water before preparing food or eating to reduce the spread of bacteria. Also wash your hands after going to the bathroom and after changing nappies.

  • Clean kitchen utensils thoroughly between uses especially if they have handled meat.

  • There is a rotavirus vaccine for babies and children that provides protection for up to five years.
