Streptococcus pneumonia in children

Streptococcus pneumonia refers to acute lung inflammation caused by Streptococcus pneumoniae (formerly known as pneumococcus). Streptococcus pneumoniae often causes inflammation in the lobules or segments of the lungs, which are primary. They are more common in children over 3 years of age, especially in older children. Therefore, the defense ability of this age group gradually matures. Can make the lesion confined to a lung lobe or a lung segment without spreading, so it is also called lobar pneumonia. Occurs occasionally in infants and young children. Due to immature immune function, the bacteria spread along the bronchus to form a lesion characterized by small airways around the bronchus (bronchopneumonia). Secondary pneumococcal pneumonia is more common in infants and young children, often secondary to viral pneumonia. Here mainly describes lobar pneumonia. The disease can occur all year round, but it is more common in winter and spring and when the climate changes suddenly.
