Gastroenteritis, clinically, is mostly caused by viral infection, hence the incubation period for patients with viral flu typically ranges from one to three days. Due to differing immune functions, patients may exhibit varied clinical symptoms. In addition to upper respiratory infection symptoms, gastroenteritis patients often experience gastrointestinal discomfort, particularly in young infants, manifesting as nausea, vomiting, abdominal bloating, and diarrhea during the outbreak. Typically, gastroenteritis patients need a week for the infection to resolve and the healing process to complete. Thus, it is crucial in clinical practice to promptly provide antiviral and symptomatic treatment to relieve symptoms. Some mild cases can be cured, but most require appropriate medication for symptomatic treatment.
