Most of the patients are asymptomatic infected or mildly infected after the new crown infection, and generally have no sequelae, while a small number of patients have sequelae in multiple systems such as respiratory, circulatory, and neurological aspects. 1. Respiratory system: Since the neocoronavirus mainly infects human lung cells, leading to dyspnea and fatigue, decreased cardiopulmonary exercise tolerance is the most common symptom in patients recovering from neocoronavirus. It may improve with time, but pulmonary fibrosis cannot be reversed in patients with heavy critical type. 2. Circulatory system: Due to myocardial damage caused by the virus, neocoronary pneumonia may lead to a variety of cardiac complications such as hypertension, arrhythmias, and coronary atherosclerosis. 3. Neurological system: Many patients suffer from decreased sense of smell, cognitive impairment, tremor and slight motor and sensory deficits, and this type of sequelae likewise improves with time. If the infection is cured by the new crown, it is important to actively participate in rehabilitation therapy to restore health as soon as possible.
