In cases of unknown GBS status, prophylactic antibiotics are given during which period?

Explanation:
The key idea is intrapartum antibiotic prophylaxis to prevent neonatal GBS infection. If GBS status is unknown, giving antibiotics during labor reduces the bacterial load in the birth canal at the moment the baby is delivered, lowering the risk that the newborn will acquire GBS during passage through the birth canal. Administering antibiotics earlier in pregnancy isn’t reliably protective at birth because colonization can change, and giving antibiotics after birth cannot prevent exposure that occurs during delivery. Cesarean prophylaxis focuses on preventing maternal surgical infection, not neonatal GBS transmission, so the most effective window for unknown status is during labor.
