Bronchitis is a very common disease in respiratory medicine and can be categorized into acute bronchitis and chronic bronchitis based on the duration of the disease. Generally, regardless of the type, the symptoms presented by patients are primarily discomfort in the respiratory tract, such as fever, fatigue, cough, expectoration, breathlessness, chest tightness, and wheezing in cases of acute bronchitis. For patients with chronic bronchitis during acute episodes, there generally is no fever, but the primary symptoms are persistent cough and expectoration, along with wheezing, breathlessness, and chest tightness. Additionally, symptoms may vary between the elderly and the young when they contract bronchitis, thus clinical symptoms are predominantly as described above.
