Lobar pneumonia

Pneumococcal pneumonia is caused by pneumococci or streptococcus pneumoniae. It is generally susceptible to children under 5 years old and older than 60 years old, accounting for more than half of out-of-hospital infections. The lung segment or lobe showed acute inflammatory consolidation, and the patient had symptoms such as chills, high fever, chest pain, cough, and blood sputum. In recent years, due to the widespread application of antibacterial drugs, clinical symptoms or atypical diseases are more common. Children can be prevented by vaccines. Currently available pneumococcal vaccines include 7-valent pneumococcal conjugate vaccine and 23-valent pneumococcal polysaccharide vaccine. Infants under 2 years of age can only receive 7-valent pneumococcal vaccine.
