Acute bronchitis is relatively common in clinical practice, especially among elderly and frail patients. Common symptoms include fever, cough, expectoration, chest tightness, and more. To prevent acute bronchitis, it is important to exercise regularly, enhance physical fitness, rest adequately, balance work and rest, and avoid overwork and staying up late. During seasons when colds are prevalent, it is advisable to drink more water, ensure room ventilation to prevent colds, and strive to improve the living and sanitary conditions to keep the air fresh. Active treatment should be sought for those with upper respiratory infections, such as diseases in the nose, pharynx, or larynx areas.
