There is a possibility of sequelae after novel coronavirus infection, and there are insufficient studies to say with certainty that there must be or must not be. According to the study, most patients had not fully recovered 6 months after discharge from the hospital. 76% of patients still had at least one symptom 6 months after onset. The most common feelings among patients were fatigue and weakness. 63% of patients experienced fatigue or muscle weakness; 26% reported sleep disturbances and 23% reported anxiety or depression. In patients with severe disease, lung function had not fully recovered after 6 months. Patients who were more severely ill at the time of hospitalization were more likely to present with decreased lung function and abnormal chest imaging 6 months after onset. Neocoronaviruses primarily attack the lungs when they enter the body, but there is increasing evidence that, in addition to the lungs, other parts of the body are also harmed. Since clinical studies on the sequelae are not yet complete, no final conclusions can be drawn. We still need to take good personal protection in our daily life by wearing masks, washing hands regularly and keeping a social distance in order to better stay away from the disease and maintain our personal health.
