Clinical details: 
Viral pathogens are the main cause of acute gastroenteritis in developed and developing countries. The clinical spectrum of acute viral gastroenteritis ranges from a self-limited watery diarrhoea illness accompanied with nausea, anorexia and mild vomiting or fever, to severe dehydration resulting in hospitalisation or even death. In the UK, rotaviruses and adenoviruses are the most common viruses causing gastroenteritis in children; almost every child in the UK has a rotavirus/adenovirus infection before they are 5 years old.
