If a patient presents with generalized aches and pains, abdominal pain, and abdominal distension, but no significant fever, home isolation may be performed first. Novel coronavirus pneumonia is mainly manifested by fever, malaise and dry cough. A small number of patients have symptoms such as nasal congestion, runny nose and diarrhea. And some patients only show low fever and mild malaise without pneumonia manifestations. Therefore, patients with no obvious fever and only generalized aches and pains, abdominal pain and bloating should also be taken seriously and can first be isolated at home by themselves. Once fever, chills, malaise, diarrhea, respiratory symptoms, etc. appear, prompt medical investigation is required.
