Bacterial meningitis Epidemiology and microbiology: the overall annual incidence of bacterial meningitis is about 2?3/100,000, with peaks of incidence in infants and adolescents. Integration of vaccines into the UK vaccination programme against Haemophilus influenzae type b (Hib) and more recently against group C meningococccus has led to a marked decline in cases of Hib and Group C meningococcal meningitis and has significantly reduced the overall incidence of bacterial meningitis.
