It’s the common tummy bug that makes you dash to the toilet.
Gastro starts with a grumbling stomach and nausea, followed by days spent in the bathroom and avoiding other people.
But what causes gastroenteritis and why is it so infectious?
GUT FEELINGS
Gastroenteritis – commonly known as gastro – is an inflammation of the digestive system.
The symptoms include vomiting, diarrhoea and stomach cramps for up to 3 days.
Unfortunately, treatment involves riding it out and drinking plenty of fluids.
This is due to the risk of dehydration from vomiting and diarrhoea. In severe cases, patients need fluids from an intravenous drip to recover.
While the symptoms are similar to food poisoning, gastro is far more contagious.
QUICK TO TRANSMIT
Gastro is caused by bacteria, toxins, parasites or viruses, which is why it’s so highly contagious.
Viral gastro is spread through contact with infected vomit or faeces, contaminated food, drinks, or objects. It’s also caught by person-to-person contact through coughing, sneezing or even shaking hands.
In 2023, a surge in gastro cases across Australia sparked warnings from health authorities to practise good hygiene and keep unwell children at home.
While infected people tend to stay home, they can still be contagious for 2 weeks after symptoms subside.
STAY FAR, FAR AWAY
Rotavirus is the most common cause of gastro in young children, which can cause dehydration and hospitalisation in severe cases.
In Australia, rotavirus vaccines are available for children under 6 months old.
The vaccines are included in the National Childhood Immunisation Schedule, reducing the risk of infants becoming infected.
For adults, the best way to prevent gastro is to keep your distance from infected people, wash your hands and sanitise your home.
That’s a small price to pay to avoid this nasty bug.
