Most babies have egg-soup-like loose watery stools, mostly caused by rotavirus infections, which are more common in autumn and winter. The main serious phenomenon of this disease is the combination of dehydration signs. If the baby is in good general condition and the vomiting is not obvious, the baby can be given antiviral and oral rehydration salts to correct the dehydration, which is given orally frequently for 24 hours, and the course of the disease is about 10-14 days. If the baby has obvious signs of dehydration, less tears when crying, reduced urine output, sunken fontanelle, etc., oral rehydration salts cannot be administered and should be treated by infusion at the hospital in a timely manner. Rotavirus vaccine is already available on the market, so you can visit your local vaccination station for consultation.
