Streptococcus Pneumoniae (the pneumococcus) is the most common bacterial cause of bacterial pneumonia in all age groups. Pneumonia is more common in the very young and the very old. Transmission of Streptococcus Pneumoniae is mostly through the spread of respiratory droplets from the nose or mouth of a person with a pneumococcal infection or from people, especially children, who carry the bacteria in their throats without being ill. The risk of pneumococcal infection is much increased in immunocompromised persons and can cause acute sinusitis, otitis media, meningitis, osteomyelitis, septic arthritis, endocarditis, peritonitis, and pericarditis.
