A persistent hacking cough lets a person know that he or she might have bronchitis. The bronchitis cause might be a virus, a bacterium, exposure to cigarette smoke, prolonged exposure to cleaning products, or by stomach acid irritating the bronchial tubes. Acute bronchitis usually lasts for a week or two. If the bronchial tubes become permanently inflamed, a patient may develop chronic bronchitis.
