Acute gastroenteritis in children is a common disease in children worldwide with a high incidence and a certain fatality rate. It is an important cause of child death in developing countries, especially in children with malnutrition and diminished human defense. Salmonella and pathogenic Escherichia coli are among the pathogens causing the acute gastroenteritis in infants. In addition, enterovirus or adenovirus can also cause the spread of gastroenteritis in some areas. The recent report of late-onset virus (rotavirus) causing acute febrile non-bacterial gastroenteritis in infants and young children has seen an increasing number and has now been proven to be the most important causative agent of acute gastroenteritis in infants and young children. . Turn infected with the virus found in Britain, Singapore, Rhodesia, India, Norway, New Guinea, Malaysia, Australia, the United States and other places.
