Answer 1

The primary causes for an acute exacerbation of COPD are air pollution and tracheobronchial infections.

Step-by-step explanation:

The primary causes for an acute exacerbation of COPD are:

1. Air pollution: Exposure to environmental pollutants such as cigarette smoke and air pollution can trigger an acute exacerbation of COPD.
2. Tracheobronchial infection: Infections in the tracheobronchial airways, such as respiratory tract infections, can lead to an exacerbation of COPD.

Other factors such as change in season, gastrointestinal viruses, and hypertension are not direct primary causes of an acute exacerbation of COPD.
