Pediatric viral enteritis, also known as infantile viral enteritis or rotavirus enteritis. These viruses are highly resistant and are mainly transmitted through the fecal-oral route. The virus can multiply in the villous cells of the small intestine, causing damage to the intestinal mucosa and affecting digestion and absorption. Infants and young children with weak gastrointestinal function, especially those aged 6 months to 2 years, can develop the disease in 1-2 days after being infected with rotavirus through food and eating utensils, or coming into contact with virus-contaminated furniture, doorknobs or toys, etc. The virus can also be transmitted in the form of aerosols. It can also be infected through the respiratory tract in the form of aerosols and cause disease. It occurs mostly in infants and young children aged 6-24 months, and is rare in those aged 4 years and above, with a rapid onset of disease, often accompanied by fever and upper respiratory tract infections at the beginning, and no obvious symptoms of infection and poisoning. Vomiting often occurs in the first 1-2 days, followed by diarrhea, diarrhea 5-6 times a day, stools are eggdrop soup-like, or watery with a sour smell, the color of the stool is light, so it is also known as white diarrhea.
