About pneumococcal disease

Pneumococcal disease is a bacterial infection caused by Streptococcus pneumoniae, sometimes known as pneumococcus. Most people carry pneumococcus in their nose and throat, where the bacteria do not cause any symptoms. However, sometimes the bacteria grow and spread to other parts of the body and that’s when you become sick.
