Rotavirus diarrhea is an acute gastroenteritis caused by rotavirus infection, which is usually most severe on the third to fifth day of illness and can result in more than a dozen stools a day. The main clinical manifestation of rotavirus enteritis, or autumn diarrhea, is recurrent diarrhea, with egg-flake soup-like or watery stools, which can even cause water-electrolyte disturbances and more serious consequences. However, the disease is self-limiting and usually heals gradually within a week or so, and early medication can shorten the course of the disease and reduce symptoms. The most important aspect of the treatment of this disease is to prevent dehydration, so the child should drink more water, or choose oral rehydration salts to avoid adverse consequences of dehydration. In addition, parents should control the child’s diet to reduce the burden on the intestinal tract, and children with severe vomiting should fast temporarily and gradually increase the amount of food when the condition improves. Parents are advised to pay attention to hand hygiene and dietary hygiene in daily life, chew and swallow slowly when eating, and avoid overfeeding at once.
