Invasive Pneumococcal Disease

Invasive pneumococcal disease is an infection caused by bacteria called Streptococcus pneumoniae. The bacteria can cause a variety of different diseases that range in severity from mild illness like ear infections, to serious invasive infections.

Invasive infections occur when the Streptococcus pneumoniae bacteria enter the sterile tissues of the body such as the blood stream. Invasive forms of infection include septicemia and pneumonia. In this report, only invasive infections with Streptococcus pneumoniae are described. Invasive infections are most common in the very young, older adults, and people with weakened immune systems and chronic health problems.

Streptococcus pneumoniae bacteria are spread from person-to-person through respiratory droplets from people with the infection. While infections can occur throughout the year, the majority of infections follow a seasonal pattern similar to influenza, which usually peaks in the winter and early spring. Pneumococcal disease is preventable with immunization. Children receive the vaccine as part of their routine immunization schedule. Vaccination is also recommended and is free of charge for all adults over the age of 65 and people with certain medical conditions. Contact a health care provider or the Health Unit for more information.
