Childhood pneumonia is mainly due to the weaker resistance of children, who are then subjected to the invasion of pathogens such as bacteria, viruses, or other agents like chlamydia and mycoplasma, leading to inflammation of the alveoli. Generally, the treatment of pneumonia is mainly targeted at its pathogens. For instance, antiviral treatment is administered for viral infections, antibacterial and anti-inflammatory treatments are required for bacterial infections, and specific antibiotics such as azithromycin or erythromycin are used for mycoplasma infections. For other types like tuberculosis and some other fungal pneumonias, specific treatments targeting those pathogens are also necessary. If the baby clearly has symptoms like wheezing or difficulty in breathing, symptomatic treatment is required. Therefore, pneumonia in children is mainly treated based on the cause, and as long as the course of treatment is sufficient, it can be cured completely. However, even after recovery, it does not mean a child will never contract pneumonia again. If the child has weak immunity or is in a high-risk environment with exposure to other patients with pneumonia cough, they might be infected again.
