title: Late, Late-Onset Group B Streptococcus Cellulitis With Bacteremia.
abstract: Group B streptococcus (GBS) infection remains a leading cause of serious neonatal and early infantile infection. As the infection often presents with nonspecific symptoms, and is associated with underlying bacteremia, prompt investigation and treatment is required. We report a case of late, late-onset GBS infection with bacteremia in a 94-day-old boy experiencing cellulitis of the left hand. Although late-onset disease or late, late-onset disease has been reported to be common among infants with underlying conditions such as premature birth, immunocompromised status, trauma, or among those using medical devices, no such underlying medical condition predisposed this infant to invasive GBS infection. Recent reports including the present case underscore the risk of GBS infection among previously healthy infants beyond the neonatal period. Thus, clinicians should especially be aware of unusual presentations of GBS invasive disease with bacteremia.
