Prevention focuses on early onset, which is the most common cause of serious infection in newborn babies. 36) This guideline provides guidance for obstetricians, midwives and neonatologists on the prevention of early-onset neonatal group B streptococcal (EOGBS) disease. GBS is not a sexually transmitted infection. Vitamin D and coronavirus: is there evidence it can help? American College of Obstetricians and Gynecologists
These antibiotics reduce the risk of your baby developing a GBS infection in their first week of life from around 1 in 400 to 1 in 4,000. Chen K, Puopolo K, Eichenwald E et al (2005) No increase in rates of early-onset neonatal sepsis by antibiotic-resistant group B Streptococcus in the era of intrapartum antibiotic prophylaxis. You should also be offered antibiotics through a drip.

If the results show that GBS is present, most women will receive antibiotics through an intravenous (IV) line once labor has started. SE1 1SZ

grunting, noisy breathing, moaning, seeming to be working hard to breathe when you look at their chest or tummy, or not breathing at all, not feeding well or not keeping milk down, have a high or low temperature and/or their skin feels too hot or cold, have changes in their skin colour (including blotchy skin), have an abnormally fast or slow heart rate or breathing rate, many women carry the GBS bacteria and, in the majority of cases, their babies are born safely and do not develop an infection, screening all women late in pregnancy cannot accurately predict which babies will develop GBS infection, no screening test is entirely accurate: a negative swab test does not guarantee that you do not carry GBS, many babies who are severely affected by GBS infection are born preterm, before the suggested time for screening (35–37 weeks). These findings are supported by other smaller studies (Hiller et al 2005; Towers et al 2010).
Even if you are not known to carry GBS, if you develop any signs of infection in labour, you will be offered antibiotics through a drip that will treat a wide range of infections, including GBS. GBS can occasionally cause serious infection in newborn babies, and, very rarely, during pregnancy and before labour. Dr Steer is Chair of the Medical Advisory Panel and GBSS. Late-onset disease also is serious and can cause meningitis. This information has been reviewed before publication by women attending clinics in Cardiff and London, by the RCOG Women’s Network and the RCOG Women’s Voices Involvement Panel, and by Group B Strep Support and their networks.

Chohan L, Hollier L, Bishop K et al (2006) Patterns of antibiotic resistance among group B streptococcus isolates: 2001-2004. S agalactiae is now best known as a cause of postpartum infection and as the most common cause of neonatal sepsis. However, if you carry GBS, there is a small chance that your baby will develop GBS infection and become seriously ill, or even die. you are not carrying GBS at this stage of pregnancy then the risk of your baby developing early-onset GBS infection is much lower (1 in 5000) and you may choose not to have antibiotics. If you are asked to make a choice, you may have lots of questions that you want to ask. Coronavirus: what are moderate, severe and critical COVID-19? Most early-onset GBS infections (in babies aged 0-6 days) can be prevented by giving intravenous antibiotics during labour to women whose babies are at particular risk of GBS infection: If you are found to carry GBS in your vagina or rectum, treating you with antibiotics before your labour begins does not reduce the chance of your baby developing GBS infection. Have a high or a low temperature, with their skin feeling very hot or cold. However GBS can, rarely, cause serious infections in babies, including sepsis, pneumonia or meningitis. This is to reduce the time that your baby is exposed to GBS before birth. women may be advised to remain in hospital for at least 24 hours after the birth so that the baby can be observed for signs of Group B streptococcus infection. More information on late-onset GBS infection is available here: www.gbss.org.uk/infection. Discussion about Group B streptococcus should take place at around 35 weeks gestation so that women have received information about preventive treatment before they go into labour. In 2015, the incidence of EOGBS in the UK and Ireland was 0.57/1000 births (517 cases), a significant increase from the previous surveillance undertaken in 2000 where an incidence of 0.48/1000 was recorded.
Women who have a cesarean birth do not need to be given antibiotics for GBS during delivery if their labor has not started and the amniotic sac has not ruptured (their water has not broken). The enriched culture medium (ECM) test is more accurate. Read ASM’s Guideline: Mifsud A, Efstratiou A, Charlett A et al (2004) Early-onset neonatal group B streptococcal infection in London: 1990-1999. In the UK, the NHS does not routinely offer all pregnant women screening for GBS.

GBS is carried in the vagina and bowel of about 3 in 10 women in the UK. Turrentine M & Ramirez M (2008) Recurrence of group B streptococci colonization in subsequent pregnancy.
your waters have broken more than 24 hours before your baby is born. giving antibiotics to all women who carry GBS would mean that a very large number of women would receive treatment they do not need. El Helali N, Giovangrandi Y, Guyot K et al (2012) Cost and effectiveness of intrapartum Group B streptococcus polymerase chain reaction screening for term deliveries. Breastfeeding has not been shown to increase the risk of GBS infection, and it offers many benefits to both you and your baby. Read ACOG’s Committee Opinion: Prevention of Group B Streptococcal Early-Onset Disease in Newbornsexternal icon. While there is no high-level evidence on the benefits of approaches to prevent transmission of Group B streptococcus, prospective and retrospective studies have identified reductions in the incidence of Group B streptococcus in the newborn associated with both routine antenatal testing (Angstetra et al 2007; Chen et al 2005; Eberly & Rajnik 2009; Phares et al 2008; Puopolo et al 2005) and risk-based testing (Trijbels-Smeulders et al 2007). How can group B streptococcus affect a newborn?
Upgrade to Patient Pro Medical Professional? This is rare and happens to 1 or 2 babies out of 100 when the mother does not receive treatment with antibiotics during labor. If, however, GBS was found in a previous pregnancy and your baby was unaffected, then there is a 1 in 2 (50%) chance that you will be carrying it again in this pregnancy. Therefore your baby may develop symptoms caused by these types of infections. In March 2020, the American Society for Microbiology (ASM) published a new guideline—Interim Guideline for the Detection and Identification of Group B Streptococcusexternal icon—which all labs should now be following. If it is thought that your newborn baby has an infection, tests will be done to see whether GBS is the cause.

Of the strategies evaluated, routine testing only is slightly more cost-effective than routine testing with treatment for certain risk factors, when compared to ‘doing nothing’.
Group B streptococcus (GBS) is sometimes also called 'strep B' or 'Group B strep'. Intravenous antibiotic treatment during labour has been shown to prevent early onset Group B streptococcus infection in 86–89% of newborns of mothers colonised before birth (Lin et al 2001; Schrag et al 2002).

It is one of many germs (bacteria) that live in our bodies and usually causes no harm. An economic analysis carried out to inform the development of these Guidelines (see separate document on economic analyses) found that the benefits of testing do not outweigh the costs involved, whatever approach is taken.
