Diarrheal symptoms may be present in a small number of patients with novel coronavirus pneumonia. Novel coronavirus pneumonia is a respiratory infection with common symptoms such as fever, cough, chest tightness, and breath-holding, but a small number of patients do present with non-respiratory symptoms such as conjunctivitis and diarrhea. Since the viral receptor is present in the intestine, it is theoretically possible for the virus to attack the gastrointestinal tract, but this symptom is less common. If diarrhea is present, the first step should be to determine whether it is caused by a new coronavirus or due to some other cause. Novel coronavirus pneumonia is a self-limiting disease, and if it is diagnosed as being caused by a novel coronavirus, recovery usually begins after 10 days, with normalization of temperature and respiratory symptoms, and improvement of diarrhea symptoms, without much intervention. If the diarrhea is obvious and the number of dilute watery stools is high, dehydration is more frequent, so timely replenishment of body fluids is needed. If the diarrhea is not caused by neoconiosis, it may be caused by other bacterial infections or other viral infections, and the cause should be actively sought. If the diarrhea is not caused by Neoconiosis, it may be caused by other bacterial infections or other viral infections. Content source: Dr. Yurai
