According to Mayo Clinic, bronchitis is described as an inflammation of bronchial tube lining. Signs and symptoms of acute or chronic bronchitis may include cough, mucus production, chest discomfort, mild fever and fatigue.
WebMD states that acute bronchitis typically results from lung infections, with the overwhelming majority of them being viral. Industrial pollution is also a common factor in the development of bronchitis. Individuals who commonly have exposure to fumes and dust, such as coal miners and metal handlers, have higher rates of chronic bronchitis than what are considered typical.
