International Group B Strep Awareness Month

United States, Canada, United Kingdom, Australia, New Zealand, Ireland

About

International Group B Strep Awareness Month is observed throughout July to raise understanding of group B Streptococcus (GBS), a common type of bacteria that can live harmlessly in the body but may cause serious illness in newborns and other vulnerable people. The observance highlights the importance of reliable information, appropriate screening, and timely medical care.

Throughout the month, families, healthcare professionals, and communities are encouraged to learn about GBS, discuss questions with medical providers, and recognize how awareness can help protect newborns from potentially severe infections. By sharing knowledge and supporting informed healthcare decisions, International Group B Strep Awareness Month promotes prevention, compassion, and healthier beginnings for families everywhere.

History

International Group B Strep Awareness Month is observed throughout July to increase understanding of group B Streptococcus (GBS), a common bacterium that can live harmlessly in the digestive and reproductive systems but may cause serious illness in newborns. The observance developed in response to continuing concerns about early-onset GBS disease, which can be transmitted from a colonized mother to an infant during labor or childbirth. Before effective prevention became widespread, GBS was a leading cause of life-threatening infections such as sepsis, pneumonia, and meningitis in newborn babies.

Its history is closely connected with advances in medical research and public-health guidance. During the late twentieth century, studies established maternal GBS colonization as an important risk factor for newborn infection, while clinical trials demonstrated that antibiotics administered during labor could substantially reduce early-onset disease. Health authorities subsequently introduced screening and risk-based prevention policies, including recommendations for testing pregnant patients late in pregnancy and offering intravenous antibiotics during labor to those at elevated risk. These measures changed GBS prevention from a relatively specialized clinical concern into a widely recognized part of prenatal and maternity care.

Over time, the July observance evolved beyond professional education to include families, patient advocates, researchers, hospitals, and nonprofit organizations. Campaigns commonly explain how GBS is detected, why a positive test does not necessarily mean illness, and how preventive treatment works. They also draw attention to the limits of current prevention strategies, including late-onset GBS disease, which can occur after the first week of life and is not prevented as reliably by antibiotics given during labor. This broader focus has encouraged continued research into vaccines, improved diagnostic methods, and more comprehensive prevention approaches.

Culturally, International Group B Strep Awareness Month gives bereaved families and survivors a public setting in which to share experiences that might otherwise remain private. Its educational message also helps reduce stigma by clarifying that GBS colonization is common and is not considered a sexually transmitted infection or a sign of poor hygiene. By connecting personal stories with medical knowledge, the observance supports informed conversations between expectant parents and healthcare professionals and reinforces the importance of evidence-based newborn care throughout July.

Timeline

1887
Edmond Nocard and Hippolyte Mollereau described Streptococcus agalactiae as a cause of bovine mastitis, marking the early identification of the bacterium now known as group B streptococcus (GBS).
1996
The U.S. Centers for Disease Control and Prevention issued its first national consensus guidelines for preventing perinatal group B streptococcal disease, recommending risk-based or culture-based prevention strategies during labor.
2002
CDC revised its perinatal GBS-prevention guidelines to recommend universal prenatal screening by culture at 35–37 weeks of gestation and intrapartum antibiotic prophylaxis for those with positive results.
2010
CDC published updated guidelines for prevention of perinatal group B streptococcal disease, consolidating evidence on screening, laboratory methods, and intrapartum antibiotic prophylaxis.
