Early onset neonatal meningitis in Australia and New Zealand, 1992-2002

Abstract

OBJECTIVES: To study the epidemiology of early onset neonatal bacterial meningitis (EONBM) in Australasia. DESIGN: Prospective surveillance study, 1992-2002, in 20 neonatal units in Australia and New Zealand. EONBM was defined as meningitis occurring within 48 hours of delivery. RESULTS: There were 852 babies with early onset sepsis, of whom 78 (9.2%) had EONBM. The incidence of early onset group B streptococcal meningitis fell significantly from a peak of 0.24/1000 live births in 1993 to 0.03/1000 in 2002 (p trend = 0.002). There was no significant change over time in the incidence of Escherichia coli meningitis. The rate of EONBM in very low birthweight babies was 1.09/1000 compared with t..
