Bronchitis is an infection of the bronchial mucosa caused by various pathogens, often secondary to upper respiratory tract infections or as a manifestation of acute infectious diseases. It is a common respiratory disease in childhood, typically caused by viruses or bacteria, or a combination of both. The treatment mainly involves symptomatic management, and when necessary, anti-inflammatory treatment can be administered. For viral infections, symptomatic treatment is usually sufficient, generally involving the use of expectorants, or if there is severe wheezing, nebulized asthma medications may be needed. For those with allergic constitutions, appropriate use of anti-allergy medications can be considered. Treatment can also integrate unique approaches from traditional Chinese medicine. If there are clear signs of bacterial infection, antibiotic treatment is necessary, and the use of antibiotics is recommended to be carried out in hospitals, with doctors prescribing appropriate antibiotics for children based on their specific conditions.
