It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal pneumonia is 900,000 annually, with almost 400,000 cases hospitalized and fatalities accounting for 5-7% of these cases. [2]
If the symptoms worsen, the pneumonia does not improve with home treatment, or complications occur, hospitalization may be required. [69] Worldwide, approximately 7–13% of cases in children result in hospitalization, [23] whereas in the developed world between 22 and 42% of adults with community-acquired pneumonia are admitted.
