Question: Which of the following best defines chronic bronchitis?

Option 1: 'Presence of bronchitis symptoms for at least three months per year over two consecutive years' This matches the classic cardiopulmonary definition of chronic bronchitis, describing a persistent productive cough with timing criteria that span multiple years, not just a single season. It aligns with the clinical criterion used to distinguish chronic bronchitis from acute bronchitis.

Option 2: 'A seasonal condition triggered by allergens and dust' This describes a seasonal allergic response or hay fever type of reaction, not chronic bronchitis. Chronic bronchitis is defined by persistent symptoms over time, not by seasonality or allergen trigger alone.

Option 3: 'A viral infection of the bronchi lasting less than three weeks' This describes an acute bronchitis episode, typically caused by a viral infection with a short duration. Chronic bronchitis, by contrast, involves long-term, ongoing symptoms over years, not a short-lived infection.

Option 4: 'Inflammation of the bronchi caused by bacterial infection' While bronchitis can involve inflammation from bacterial infection in some cases, chronic bronchitis is not defined purely by a bacterial cause. The defining feature is the duration and frequency of symptoms (three months per year for two consecutive years), regardless of the exact etiologic agent.

In summary, Option 1 accurately captures the standard definition of chronic bronchitis, while Options 2–4 describe conditions or scenarios that do not meet the chronic, long-duration criteria for chronic bronchitis.
