Increasing Burden of Invasive Group B Streptococcal Disease in Nonpregnant Adults, 1990–2007

摘要

Background. Group B Streptococcus (GBS), traditionally considered to be a neonatal pathogen, is an important cause of morbidity and mortality among older adults and among those with underlying medical conditions. We used population-based surveillance to examine trends in adult GBS disease during the period 1990–2007 and to describe the epidemiology of adult GBS disease to guide prevention efforts.
