Pneumococcal disease is a very serious illness, with resulting infections being the most common cause of invasive bacterial infection in US children. Invasive pneumococcal disease and pneumonia kills thousands of people in the US each year, most of them age 65 years and older.
Everyone who is a carrier of the bacteria causing pneumococcal disease will get sick from it.
It is common for people, especially children, to carry the bacteria in their throats without getting sick from it.
Only adults age 65 years and older are at risk for pneumococcal disease.
Anyone can get pneumococcal disease. In addition to adults age 65 years and older, high-risk groups include individuals who smoke cigarettes and those with certain chronic health conditions, including those that weaken the immune system (HIV/AIDS, cancer, or damaged/absent spleen), cochlear implants, or cerebrospinal fluid (CSF) leaks. In addition, children under age 2 years and those with certain medical conditions are at increased risk.
