The general symptoms of novel coronavirus infection include fever, malaise, dry cough, and progressive dyspnea. Some patients with moderate to severe disease have a mild onset with moderate to low fever or may even have no significant fever. In severe cases, acute respiratory distress syndrome, septic shock, uncorrectable metabolic acidosis, and outgoing coagulation dysfunction may occur. In addition, some of the symptoms may not be typical, such as nausea, vomiting, diarrhea and other digestive system symptoms; headache and other neurological symptoms; cardiovascular system symptoms such as panic and chest tightness; and mild muscle pain in the extremities or lower back. Since the symptoms of this disease are diverse, patients are not advised to make judgments based on symptoms alone.
