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
- The incidence of Hemophilius influenza meningitis is higher in children younger than 5 years of age, rate estimated to be 31 cases per 100,000.[2]
- The incidence of Streptococcus pneumoniae in very young and very old individuals is estimated to be 17 cases per 100,000 making it the most common cause of meningitis in this age group.[3]

Geographical distribution
- The frequency of different bacterial causes of meningitis may vary in different parts of the world.[4]
- Meningococcal meningitis is commonest cause of meningitis epidemic in developing world. However, it is relatively uncommon cause of meningitis in USA and Europe.[5][6][7]
- 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.[8]
