There are obvious differences between gastrointestinal colds and novel coronavirus infections, as follows: 1. Gastrointestinal colds: caused by coxsackievirus infection, which is a special type of common viral cold, not an infectious disease. Patients with gastrointestinal type cold mainly have gastrointestinal symptoms, patients are mostly accompanied by obvious nausea, vomiting, abdomen, stuffiness, diarrhea and other discomforts, and sometimes can be accompanied by mild upper respiratory cartilage symptoms and low fever, etc.; 2. New coronavirus infection: is extremely contagious and belongs to category B infectious diseases. Patients with new coronavirus pneumonia can have diarrhea in a few cases. Such patients have dry cough, fever and malaise as the main manifestations, and they mostly have a history of new coronavirus epidemiology, and some severe patients can also have shortness of breath and chest tightness. When the nucleic acid test for New Coronavirus is positive, the patient can be diagnosed with New Coronavirus pneumonia infection and needs to be isolated and treated.
