Overview
Epidemiology
Incidence
Prevalence
Demographics
Age
- The frequency of different causative agents causing bacterial meningitis varies with different age groups
- There is increased incidence of bacterial meningitis with increasing age
- In USA, the incidence rate is 0.66 cases per 100, 000 in age groups from 18 to 34 years compared to 1.92 cases per 100, 000 in age group >65 years of age.[1]
- The case fatality rate in USA in age group 18-34 years of age is 16.4 percent compared to 22.7 percent in individuals >65 years of age

Geographical distribution
- The frequency of different bacterial causes of meningitis may vary in different parts of the world.
- Meningococcal meningitis is commonest cause of meningitis epidemic in developing world. However, it is relatively uncommon cause of meningitis in USA and Europe.[2]
- In African countries the streptococcus pneumoniae is the most common cause of high mortality rates due to bacterial meningitis.
- In USA, the overall incidence of bacterial meningitis has decreased significantly since the emergence of vaccine against Hemophilus influenza and Streptococcus pneumoniae.[1]
- Streptococcus suis is the new emerging cause of bacterial meningitis in Asia.[3]
