Gastroenteritis does not lead to infection. In itself, there are two aspects of gastroenteritis: first, functional gastroenteritis, most of which is a dysfunction of the plant nervous system leading to recurrent intestinal dysfunction, causing symptoms of diarrhea, abdominal pain, nausea and vomiting. Second, inflammatory infections lead to gastroenteritis, mostly viral and bacterial infections, mostly related to cold, flu, or eating unclean, poorly digested food. This condition is mostly accompanied by fever, abdominal pain, general weakness, etc. It is necessary to give anti-inflammatory rehydration symptomatic support treatment, and even treatment to prevent water-electrolyte disturbance balance. Therefore, the appearance of gastroenteritis will not lead to the occurrence of infectious diseases, but if the pathogenic bacteria or contact with the pathogenic bacteria is not cleared, other patients who are exposed to the same symptoms can lead to the same symptoms after the occurrence of the patient itself is not infectious, so do not worry too much.
