Rotavirus is the main pathogen of acute infectious diarrhea in infants and young children, also known as “autumn diarrhea”, which is usually transmitted by the fecal-oral route, and its clinical manifestations are mainly acute watery diarrhea, some children may be accompanied by vomiting, fever and other symptoms, and the symptoms usually last 3-9 days. Rotavirus infection is self-limiting and generally does not require antiviral treatment. The main treatment principle is to correct water-electrolyte disturbances and prevent dehydration. Children with rotavirus diarrhea should be actively treated with rehydration support, including oral rehydration salts, encouragement to drink more water and eat liquid, easy-to-digest soft food, and gradually transition to normal diet after diarrhea symptoms are relieved; if the child cannot eat due to severe vomiting symptoms, and the child has obvious symptoms of dehydration, such as reduced skin elasticity, little urine, sunken eyes, crying without tears, etc., intravenous rehydration treatment is required, and attention should be paid to maintaining The electrolyte and acid-base balance should be maintained. The use of antibacterial drugs is generally not necessary for rotavirus diarrhea because they are ineffective in treating the etiology of rotavirus, and their use may lead to antibiotic abuse and dysbiosis of the intestinal flora. In conclusion, the treatment of rotavirus-induced infectious diarrhea is mainly symptomatic treatment, active correction of dehydration, and good stool handling to avoid transmission; there is also a self-funded vaccine for rotavirus prevention, which can be administered at the local program immunization center before the onset of autumn.
