Early onset group B streptococcal neonatal infection in Oxford 1985-96

Abstract

Of 74 920 babies live born in Oxford between 1985 and 1996, 41 (0.5 per 1000 95% GI 0.4-0.7) developed definite, culture confirmed, early onset (<48 hours) group B streptococcal infection and 32 (0.4 per 1000 95% GI 0.3-0.6) developed probable infection (sepsis plus colonisation). There was no significant variation in incidence with time. The mortality from definite infection was 19.5%, and from probable infection 6%. These data suggest that the incidence of group B streptococcal infection in Oxford is considerably lower than that reported in the USA.
