This was a completely preventable case involving group B streptococcus (GBS). Asymptomatic carriage of GBS is common in women, especially in the vaginal and rectal areas. The mother was a carrier of GBS and passed the infection onto her son during a vaginal birth. Unknown to the medical staff due to their failure to conduct a simple swab test. Her son was completely healthy but developed the serious early onset infection of neonatal sepsis and its unfortunate sequalae, including severe neurological complications and cerebral palsy.
