Overview
Brief Summary
A prospective, multi-center, observational clinical trail. Aim to evaluate the real incidence of chronic obstructive pulmonary disease (COPD) pertussis and the impact of pertussis on COPD exacerbation.
Detailed Description
1. Investigate the incidence and epidemiological characteristics of pertussis infection in COPD population. 2. To explore the relationship between pertussis infection and COPD exacerbation.

Outcomes
Primary Outcomes
Evaluation of the prevalence of pertussis among COPD
Time Frame: Day 0 of each subject at the time of enrollment.
According to the positive rate of bordetella pertussis nucleic acid, evaluate the prevalence of pertussis in COPD.
Evaluation of the correlation between pertussis and COPD exacerbation
Time Frame: Day 0 of each subject at the time of enrollment.
Evaluate the correlation between pertussis infection and COPD exacerbation by pertussis positive rate and exacerbation degree.
Secondary Outcomes
- Evaluation of the cut-off value for serological diagnosis of pertussis.(Day 0 of each subject at the time of enrollment.)
- Evaluation of the seroprevalence of Bordetella pertussis in COPD(Day 0 of each subject at the time of enrollment.)
- Evaluation of the subtype of bordetella pertussis.(Day 0 of each subject at the time of enrollment.)
