Stomach Infection

Viral or bacterial gastroenteritis

Many people around the world suffer from viral or bacterial gastroenteritis. The
stomach bug can have a number of causes, be it diet habits or poor food hygiene, but
is less likely to bring on frequent diarrhoea. It is an uncomfortable illness, but don’t
worry as it’s very common and usually lasts only a few days.

About gastroenteritis

Diarrhoea, often accompanied by nausea or vomiting, headaches and a mild fever, are common symptoms of an infection in your stomach and intestines known as bacterial or viral gastroenteritis. Bacterial or viral gastroenteritis affects approximately 8 out of 10 people every year1. In most cases, you’ll get better in a few days without the need for a doctor but some vulnerable groups, including young children, the sick and the elderly, will need medical advice. You should seek medical advice if you experience fever or blood in your stool.

Is it infectious?

Unfortunately, gastroenteritis can be extremely infectious. If you do catch it, then it’s best to make sure you wash your hands after going to the toilet and especially if preparing food for other people. If possible, try to stay at home as much as you can until the diarrhoea and vomiting has stopped.
