Rotavirus gastroenteritis can be transmitted both through the gastrointestinal tract and through the respiratory tract, making parents feel overwhelmed. Rotavirus infections can occur throughout the year, but fall and winter are the most frequent seasons, so it is called “autumn diarrhea”. Second, what are the characteristics of autumn diarrhea? The clinical manifestation of autumn diarrhea is acute gastroenteritis, the baby’s stool is yellow and watery, most of them are also accompanied by fever, other accompanying symptoms include abdominal distension, abdominal chirping, abdominal pain and nausea, vomiting, etc. Rotavirus usually stays in the body for 5-7 days, and is a self-healing disease process. When a baby has suspected symptoms of fall diarrhea, stool specimens can be taken for direct rotavirus antigen testing, with negative stool routine and positive stool rotavirus antigen. Third, is oral rotavirus vaccine useful? Oral rotavirus vaccine can prevent fall abdominal occurrence, some babies may become infected after oral rotavirus vaccine, but the symptoms are generally very mild.
