Question
Why would such a young child develop pneumonia? Under what circumstances might this illness occur? The child is currently in the hospital, and the doctor said the condition is severe. I want to understand the background of this disease.
Answer
Pneumonia is typically caused by bacterial or other pathogenic infections, which may be related to inadequate care or malnutrition in children. When a child catches a cold, pathogens can enter the nasal passages. If clothing is not added in time, pathogens may then enter the trachea and lungs, leading to pneumonia. Since infants cannot cough up phlegm, the phlegm cannot be expelled, causing a slow recovery from pneumonia.
