Gastroenteritis and the common cold generally manifest as two types of symptoms in clinical settings. The first type includes symptoms caused by upper respiratory tract infections. The second type involves gastrointestinal symptoms. Common symptoms of upper gastrointestinal tract infections include fever, fatigue, dry cough, coughing, sore throat, runny nose, and itchy throat, etc., typically lasting about a week. These symptoms are usually nonspecific and similar to those of a typical upper respiratory tract infection. The second type of symptoms generally involves gastrointestinal issues, presenting as abdominal discomfort, bloating, leg pain, and abnormal stool. Clinically, abnormal stools are often looser and more frequent, but typically do not involve bloody stools. These symptoms are generally not severe and can be observed.
