(1) Cough, long-term, repeated, and gradually worsening cough is a prominent manifestation of this disease. The mild ones only occur in the winter and spring seasons, especially before and after getting up in the morning, and there is less cough during the day. Cough reduces or disappears during summer and autumn. In severe cases, the cough in the four seasons, the winter and spring intensified, coughing day and night, especially in the morning and evening.

(2) Cough is generally a white mucus foam, which is more frequent in the morning and often does not easily smear due to stickiness. Symptoms rapidly increase after infection or cold, increased sputum, increased viscosity, or yellow purulent sputum or wheezing. Occasionally because of a cough and blood in the sputum.

Differential diagnosis

The disease is often exposed to irritating chemical gases, and is significantly different from other respiratory diseases in the etiology. Chronic bronchitis refers to chronic non-specific inflammation of the trachea, bronchial mucosa and surrounding tissues. It is clinically characterized by a cough, cough, or chronic process accompanied by wheezing and recurrent episodes. Acute bronchitis: The main symptom is cough, the beginning of the disease, short, dry and cough. After 3 to 4 days, as the exudate increases, it becomes wet and coughs, and the pain is reduced. It is often accompanied by vomiting after coughing. Allergic bronchitis refers to a special type of asthma with chronic cough as the primary or only clinical manifestation. In the early stage of asthma, about 5-6% are persistent cough as the main symptom, mostly at night or in the early morning, often irritating cough, which is often misdiagnosed as bronchitis. Because cough is a non-specific symptom of many diseases, it is necessary to ask for detailed medical history, comprehensive physical examination, chest X-ray or CT, airway responsiveness measurement, pulmonary function, electrocardiogram, fiberoptic bronchoscopy and some special cases. Check to rule out other diseases that can cause chronic, intractable cough.
