Rotavirus diarrhea stools tend to be white rice soup-like or yellow-green egg-like loose stools in color. Rotavirus diarrhea is an infectious diarrhea of the gastrointestinal tract caused by the rotavirus, which attacks children under 5 years of age mainly from November to May each year. Rotavirus is highly contagious and spreads mainly through the fecal-oral route, but also through the respiratory tract. Young children can be infected through contact with contaminated hands, toys and other items. When children are infected with rotavirus, they usually present with acute gastroenteritis as the main clinical symptom, i.e., watery diarrhea, accompanied by fever, vomiting and abdominal pain, and the diarrhea is mostly white rice soup-like or yellowish-green eggdrop soup-like dilute stools with bad smell, and in severe cases, it can lead to death due to dehydration and complications such as pneumonia and toxic myocarditis. Rotavirus diarrhea can be prevented by encouraging breastfeeding, paying attention to dietary hygiene, and receiving rotavirus vaccination. For rotavirus diarrhea, it is recommended to consult a doctor for diagnosis and treatment.
