Chest tightness is not the main symptom of novel coronavirus pneumonia. The vast majority of patients with coronavirus infection mainly present with fever, dry cough, general malaise, etc. Some severely ill patients may have dyspnea and chest tightness. However, the above symptoms are often not characteristic and do not have diagnostic significance. For this disease, an accurate diagnosis cannot be obtained simply by relying on various symptoms. If a suspected infected person has a history of epidemiological exposure and presents with symptoms such as chest tightness and fever, he or she should promptly seek medical attention at each regional fever clinic to determine whether the criteria for a suspected case of novel coronavirus pneumonia are met and to determine whether pathogenic testing is needed.
