Symptoms of nausea and vomiting can occur after novel coronavirus infection. In most patients with novel coronavirus pneumonia, fever, malaise, and dry cough are the main manifestations. Upper respiratory symptoms such as nasal congestion and runny nose are rare, and some patients do not have fever. About half of the patients develop dyspnea after a week, but not all patients have fever, or cough as the first symptom. As the symptoms of novel coronavirus pneumonia are diverse, some patients have the first signs of digestive symptoms, such as nausea, vomiting, diarrhea, mild nausea, fatigue, and poor mental health.
