Pneumococcal Disease
Serious bacterial infection of special concern to Elders and young children
Overview
Pneumococcal disease is a serious infection caused by a bacteria called pneumococcus (Streptococcus pneumoniae). It often causes ear and sinus infections but can also spread to parts of the body where bacteria aren’t usually found. This is called invasive pneumococcal disease and can lead to serious illnesses like pneumonia, blood infections, or meningitis (swelling around the brain and spinal cord).
Children under 2, adults 65 and older, Alaska Native adults 50 and older, and people with certain health conditions are at higher risk.
Symptoms and Diagnosis
Mild cases don't usually cause complications, but serious cases can lead to lasting health issues or death.
Symptoms depend on the infected body part and are similar to other bacterial infections. For most types, except pneumonia, it's unclear how long symptoms take to appear after infection.
Diagnosis requires specific lab tests used for different types of infections.
