Exclusion Criteria:

• Major diseases except COPD; Significant abnormality in laboratory examination; Clinical diagnosis of lung cancer, bronchiectasis, pneumoconiosis or other simple restrictive ventilation dysfunction; Patients with a history of asthma, allergic rhinitis, or a blood eosinophil count of 2600/mm3 (0.6x10^9/L) within 4 weeks; Currently suffering from active tuberculosis; Patients with life-threatening pulmonary embolism, or al-antitrypsin deficiency, or cystic fibrosis; Patients who have undergone lung resection.

Related Conditions & MeSH terms

• COPD Exacerbation
• Pertussis
• Whooping Cough

Intervention

Procedure:
• Blood sample
2 ml venous blood was collected and separated into serum.

Other:
• Data collection
Whether the patient has been vaccinated with DPT vaccine and record the time of vaccination; Medication situation of patients in the past year, including rescue drugs, antitussive and expectorant drugs, inhaled corticosteroids and antibiotics; Assess COPD using ABCD assessment tool.

Procedure:
• Throat swab
Before the collection of oropharyngeal swabs, instruct the patient to wash the mouth or gargle, fix the patient's head, open the mouth and expose the throat. If necessary, use a tongue depressor to gently press the tongue. Use the swab to wipe the secretion on both sides of the palatal arch, pharynx and tonsil with a sensitive and gentle action, and quickly withdraw the swab to avoid contacting other parts of the mouth. Put the swab in the sterile test tube, plug the opening with cotton ball, and send it for inspection and registration in time.
