Novel coronavirus infection can cause great harm to the human body, most notably by causing major damage to the lungs, such as chest tightness, dyspnea, emphysema, and so on. Clinical manifestations such as panic attacks and dyspnea may also occur. Pulmonary function tests may indicate hypoxemia and impaired ventilation, and in severe cases, respiratory distress syndrome and multiple organ failure may occur. In addition, there can be some harm to the gastrointestinal tract. Some patients may have digestive symptoms such as abdominal pain and diarrhea. Some patients may have symptoms related to the conjunctiva, such as acute conjunctivitis.
