Lu Lijun, deputy chief physician of the Department of Pulmonary Diseases of Wuhan Hospital of Traditional Chinese Medicine, said that after infection with the new coronavirus, even if the nucleic acid and antigen are negative, the cough symptoms still do not disappear, mainly because Omicron virus infection damages the respiratory mucosa .

Coughing is a protective mechanism of the human body . Coughing after infection is a common symptom of many respiratory virus infections. Generally, there is no need to be too nervous .

Cough and pneumonia are different concepts. Cough is only a symptom of the disease and does not cause pneumonia itself. When viruses bacteria and other pathogens only affect the upper respiratory tract but not the lower respiratory tract, cough symptoms usually occur; and when inflammation involves the lower respiratory tract, it may develop into pneumonia .

If you cough up blood (blood in sputum), your cough gets worse at night (or when you change your body position), you cough up a lot of yellow purulent sputum, or you have a fever again, you have shortness of breath, , difficulty breathing, chest pain and other original symptoms that get significantly worse, or if your cough lasts for more than 2 weeks, it is recommended to go to the hospital for treatment.

Fu Guiling, chief physician of of Beijing Changping District Hospital of Integrated Traditional Chinese and Western Medicine, reminded not to cough forcefully with your throat . This will not only fail to effectively clear respiratory secretions, but will also cause sore throat and hoarseness. Especially for those with a history of cerebral blood vessel rupture, embolism or hemangioma, coughing with force should be avoided.

Fu Guiling specially reminded that we should pay attention to the treatment of cough. If the cough is not cured for a long time, do not "hardly carry it" to prevent minor lesions from serious diseases. You should go to the relevant departments of the nearest hospital for treatment in a timely manner.
