Most novel coronavirus infections present with fever, malaise, and dry cough, and most severe patients develop respiratory distress a week after onset. Only a few patients have atypical symptoms and may only have digestive symptoms as the first manifestation, such as vomiting, nausea, diarrhea and poor appetite. Therefore, patients should not be overly concerned if they have atypical symptoms such as vomiting, as not all vomiting is due to novel coronavirus infection, but may also be caused by simple digestive disorders. However, if the patient has a significant epidemiological history, a clear diagnosis needs to be made promptly at the hospital.
