It is impossible to generalize how old pediatric wheezing bronchitis will last, although the disease is usually seen only in children aged 1-3 years. Wheezing bronchitis, which usually occurs in children under 3 years of age, is a common clinical respiratory disease that is caused by edema and spasm of the respiratory mucosa due to inflammatory irritation. The disease is a special type of bronchitis, with symptoms of wheezing in addition to bronchitis symptoms such as fever and cough, and it worsens after activity and crying. It is more likely to occur in the winter, but most cases are not serious, but if the child has breathing difficulties, he or she needs to be hospitalized. In daily life, it is important to keep the child warm and avoid catching a cold to avoid aggravating the condition. Drink plenty of water and take care of nutrition to improve the child’s resistance and help him/her recover.
