H influenzae meningitis primarily affects infants younger than 2 years. S agalactiae meningitis occurs principally during the first 12 weeks of life but has also been reported in adults, primarily affecting individuals older than age 60 years. The overall case-fatality rate in adults is 34%. Among the bacterial agents that cause meningitis, S pneumoniae is associated with one of the highest mortalities (19-26%).
