Newborns of mothers with laboratory-confirmed infection had an odds ratio of 6.6 (95%CI 3.9-11.2) for laboratory-confirmed infection themselves compared with newborns of mothers without laboratory-confirmed infection. Newborns of mothers with colonization had an odds ratio of 9.4 (95%CI 3.1-28.5) of laboratory-confirmed infection compared with newborns of non-colonized mothers. Furthermore, newborns of mothers with risk factors for infection (prelabour rupture of membranes, preterm <37 weeks prelabour rupture of membranes, and prolonged rupture of membranes) had an odds ratio of infection of 2.3 (95%CI 1.0-5.4) compared with newborns of mothers without risk factors.
