Rotavirus enteritis, also known as fall diarrhea, refers to an intestinal viral infection that tends to occur in the fall and winter months, and it is a self-limiting illness. Stools are typically characterized by the three polymorphisms, i.e., more volume, more frequency, and more water in the stools. The number of stools averages about 5-10 times a day, and in severe cases it can reach 20 times or more. Stools sometimes contain mucus or egg-like pattern with indigestible milk petals, and in the case of frequent stools, the baby may show signs of dehydration and acidosis. If your baby has rotavirus enteritis, if the symptoms are mild, you can take montelukast to protect the gastric mucosa, and then take some mama’s love or bifidobacteria to adjust the gastrointestinal function, and you can also take oral rehydration salts to prevent dehydration. Breastfeeding mothers should pay attention to avoid eating fish, shrimp, hair products and stimulating food. If the baby’s symptoms are more serious, especially the frequency of stools, dehydration or even acidosis, the baby’s mental state is not good, it is recommended to go to the hospital in time.
