GASTROENTERITIS

Common infection of the stomach and intestines, transmitted mainly by the faecal–oral route and usually highly infectious. Presents with diarrhoea, vomiting and abdominal pain following consumption of infected food or drink (food poisoning) or contact with an infected individual. The rotavirus is the leading cause of gastroenteritis in children. Always ask about recent travel. Usually mild and self-limiting. Individuals with severe symptoms or vulnerable because of age or other illness may need hospital treatment to manage dehydration. Patients should stay away from work or school until 48 hours after last episode of diarrhoea or vomiting.
