How effective are antibiotics in preventing GBS transmission to newborns?
Antibiotics administered during labour to pregnant women who test positive for Group B Streptococcus (GBS) are highly effective in preventing transmission to newborns. They significantly reduce the risk of early-onset GBS infection in newborns by about 80% and help prevent GBS colonisation in the baby during delivery.
Antibiotics are typically given intravenously during labour, ideally starting at least 4 hours before delivery. They effectively target and eliminate GBS bacteria present in the birth canal at the time of delivery.
Antibiotics used for GBS prevention are chosen to minimise the risk of developing antibiotic resistance. Healthcare providers monitor both mother and baby closely after birth to ensure any signs of infection are promptly addressed.
