Statistics regarding invasive pneumococcal disease in the United States are based on active surveillance using the Centers for Disease Control and Prevention (CDC) Active Bacterial Core Surveillance (ABC) system. Calculations for 2010 estimated 39,750 (12.9 cases per 100,000 population) cases of invasive disease nationally, with 4,000 (1.3 cases per 100,000 population) estimated deaths. (Comparable 2008 data showed 44,000 (14.5 cases per 100,000 population) episodes of invasive disease with 4,500 (1.5 cases per 100,000 population) deaths. [6]

Children younger than 5 years and adults older than 65 years are 2 identified age groups in whom rates of disease and death are increased. In 2010, rates of pneumococcal invasive disease in these groups were estimated to be 19 per 100,000 population and 36 per 100,000 population, respectively. This compares with rates of 20.2 and 40.4 in 2008, 21.8 and 39.2 in 2007, and 23.2 and 43.3 in 2002, respectively. More than half of deaths due to invasive pneumococcal disease occur in adults with specific risk factors (age, immunosuppression) for severe disease. Such risk factors are an indication for vaccination. [6, 37]
