Patient's question:
What is acute bronchitisDoctor's answer:
Bronchitis is primarily caused by infections of pathogens such as bacteria and viruses in the trachea and bronchi, leading to inflammatory reactions in the tracheal and bronchial mucosa. The main symptoms are coughing, generally without fever, and some may have phlegm. Auscultation reveals non-fixed dry rales in both lungs. This condition is a common and frequently occurring disease, especially prevalent among children and the elderly. It is mostly caused by viral infections of the upper respiratory tract, with cold exposure being the primary cause. Autumn and winter are the peak seasons for this disease, and it is also more common in cold regions.
