The main clinical manifestations are fever, abdominal pain, bloating, diarrhea, vomiting, etc., which means that the main symptoms are gastrointestinal. Gastrointestinal colds are mainly due to the imperfect development of the gastrointestinal function of children, and when infected with the virus, there will be respiratory symptoms such as fever, sneezing and runny nose, as well as more obvious gastrointestinal symptoms, such as nausea and vomiting, not eating, loose stools, and older children will actively complain of stomach discomfort. Sometimes it is easy to misdiagnose it as diarrheal disease. When a child has these symptoms, it means that the child has a gastrointestinal cold. In terms of treatment, medications for gastrointestinal symptoms can be used if necessary. Gastrointestinal flu is also a type of acute upper respiratory tract infection. Most of them are also caused by viral infections, so it is very important to treat them aggressively and symptomatically. When the combination of bacterial infection is clear through laboratory tests, then consider using antibiotics according to the condition.
