To the Editor: Meningitis is one of the most serious infections in young children. The annual incidence of Haemophilus influenzae type b (Hib) meningitis between 1984 and 1988 was 150 per 100 000 population in Aboriginal children and 27 per 100 000 in non-Aboriginal children younger than 5 years.1 A conjugate Hib vaccination program was introduced in Western Australia in January 1993, before a nationwide program commenced in July 1993. Subsequent marked declines in incidence of Hib meningitis have been reported.2-4 However, there are no recent reports on trends in overall admissions for meningitis.
