Algorithms and Tables

Revised Guidelines for the Prevention of Perinatal Group B Streptococcal (GBS) Disease were recently released from CDC. These 2010 guidelines were developed using an evidence-based approach in collaboration with several professional associations.*

Below are printable algorithms and tables from the 2010 guidelines.

Intrapartum Antibiotic Prophylaxis
