Prenatal-onset GBS Disease Recognition Month - Support mothers and spread knowledge about G.B.S. disease to save lives this Prenatal-onset G.B.S. Disease Recognition Month.

Prenatal-onset GBS Disease Recognition Month 2025 – October 2025

Prenatal-onset G.B.S. Disease Recognition Month occurs every October. It was initiated by Group B Strep International. The three types of G.B.S. are prenatal-onset, early-onset, and late-onset but prenatal-onset is often overlooked or not recognized.G.B.S. stands for Group B Streptococcus. This is bacteria that is found in the intestine, vagina, and rectum in about 25% of all healthy pregnant women. Newborn babies and adults can be infected by group B strep and most pregnant women who have the bacteria have no symptoms.G.B.S. can infect the urinary tract, placenta, womb, and amniotic fluid. This infection can also be passed to babies during labor and delivery.

History of Prenatal-onset GBS Disease Recognition Month

Prenatal-onset G.B.S. Disease Recognition Month aims to promote awareness that group B strep (G.B.S.) can infect babies even before birth. It is sponsored by Group B Strep International. In April 2006, Group B Strep International was formed. It was created by John MacDonald and Marti Perhach who each lost a daughter to group B strep. It began as a national project in conjunction with a sister organization but then expanded its scope and the audience of the campaign worldwide.Early-onset (birth through the first week of life) and late-onset (after the first week of life to several months of age) are the two types of G.B.S. disease that current medical literature acknowledges. However, babies are also susceptible to group B strep during pregnancy.It was in the late 1880s that G.B.S. was first recognized as a pathogen by Edmond Nocard and Mollereau. In 1938, three fatal cases of puerperal infections caused by G.B.S. were reported. This was the first mention of the significance of G.B.S. as a human pathogen. By the early 1960s, G.B.S. was recognized as the main cause of infections in newborns.Generally, G.B.S. is a harmless bacterium that is part of the human microbiota colonizing the gastrointestinal and genitourinary tracts of up to 30% of healthy human adults. In the western world, G.B.S. is the main cause of bacterial infections in newborns, such as sepsis, pneumonia, and meningitis. This can lead to death or long-term after-effects.Fortunately, early-onset G.B.S. fatality rates have declined, from 50% observed in studies from the 1970s to between two and 10% in recent years.In 2000–2001, the reported overall incidence of G.B.S. infection in newborn babies in the U.K. was 0.72 per 1,000 live births. Today, the mortality associated with early-onset G.B.S. E.O.D. in the U.S. is 2.1% among term newborns and 19.2% among preterm newborns.In the United States and Canada, the rate of early-onset infection reduced by more than half from 0.7 cases per 1000 live births in the U.S in 1997. In 2004, it reduced to 0.32 cases per 1,000 live births.Even though group B strep can infect babies before birth, Prenatal-onset G.B.S. is not yet a widely-known disease. There are no official statistics on how many babies have been miscarried or stillborn due to G.B.S. It is believed that the reason prenatal-onset G.B.S. disease has not been officially recognized is that general medical opinion considers G.B.S.-caused miscarriages and stillbirths to be rare occurrences.

5 Facts About Group B Strep

  1. One in four pregnant women carry G.B.S.

    About one in four pregnant women carry G.B.S. bacteria in their bodies.

  2. There may be no symptoms

    People may be asymptomatic which means G.B.S. bacteria may come and go in people’s bodies without symptoms.

  3. It can likely cause meningitis

    In the United States, the leading cause of meningitis and bloodstream infections in a newborn’s first three months of life is G.B.S. bacteria.

  4. Newborns of infected mothers are at risk

    If the mother tests positive during pregnancy, the risk of newborns getting G.B.S. disease increases.

  5. The bacteria grows back quickly

    Pregnant women must take antibiotics during labor to prevent early-onset of G.B.S. disease in newborns; the antibiotics only help during labor because the bacteria grow back quickly.

Why Prenatal-onset GBS Disease Recognition Month is Important

  1. It exposes people to an important reality

    Most people out there are still unaware of even the existence of G.B.S. Any information on it is life-saving and should be shared widely.

  2. It helps us become better parents
