Now that we have entered the autumn and winter season, acute gastroenteritis in infants and children caused by rotavirus or other viruses (such as norovirus, coxsackievirus, etc.) infection is very popular in the south. Therefore, parents of children with this disease should closely observe the changes in the child’s condition, especially paying attention to the child’s mental status, changes in urine output, and limb circulation. In addition, the disease may cause frequent convulsions in a short period of time in a small number of children, which may be caused by fever, electrolyte disorders, viral encephalitis, etc. Some children may have benign convulsions.
