Protect Your Baby from
Group B Strep (8/7/08)
If you or someone you know is pregnant, you need to know about “group B
strep." Group B streptococcal bacteria (also called GBS, group B strep, or
baby strep) is very common in all types of women and can be passed on to a
baby during childbirth. Protect babies from group B strep. If you are 35-37
weeks pregnant, ask your doctor or nurse about a group B strep test.

Group B streptococcus (group B strep) is a type of bacteria that causes
illness in newborn babies, pregnant women, the elderly, and adults with
other illnesses. Group B strep is the most common cause of life-threatening
infections in newborns. Find out what you can do to prevent and treat group
b strep.

Rate of Very Low Birthweight, by Age of Mother and Multiple-Birth Status-
United States, 2003 (12/30/05)

The risk of giving birth to a very low birthweight infant is higher for both
younger and older mothers. Much of the added risk among older women is attributable
to higher multiple birth rates. On average, infants born in multiple births
are smaller than infants born in single births.

As part of the Minnesota Department of Health Emerging Infections Program,
prenatal care providers in Minnesota were surveyed in April 1998 to determine
strategies to prevent perinatal GBS disease. In November 2002, a similar survey
was undertaken to determine the extent to which Minnesota providers have adopted
the revised 2002 CDC guidelines.
Disparities
in Universal Prenatal Screening for Group B Streptococcus- North Carolina,

To examine prenatal Group B streptococcus (GBS) screening among pregnant women
in North Carolina, CDC analyzed 2002 and 2003 data from the North Carolina
Pregnancy Risk Assessment Monitoring System. The proportions of women reporting
prenatal screening for GBS were similar in 2002 and 2003 (70% and 74%, respectively);
however, for both years, women of Hispanic ethnicity and women who received
prenatal care at a hospital or health department clinic were less likely to
report prenatal screening for GBS.

Diminishing
Racial Disparities in Early-Onset Neonatal Group B Streptococcal Disease-
United States, 2000-2003 (6/30/04)

PDF (p. 502)
http://www.cdc.gov/mmwr/PDF/wk/mm5323.pdf
In 2002, CDC and the American College of Obstetricians and Gynecologists revised
guidelines for prevention of early-onset GBS disease to recommend late prenatal
screening of all pregnant women and intrapartum antibiotic prophylaxis for
GBS carriers. This report updates early-onset incidence trends since 1999 and
indicates that 1) after a plateau in early-onset disease incidence during 1999-2002,
rates declined 34% in 2003 and 2) although racial disparities in incidence
persist, rates for blacks now approach the 2010 national health objective of
0.5 cases per 1,000 live births. Continued implementation of screening and
prophylaxis guidelines by clinicians and public health practitioners should
lead to further declines in racial disparities.

This report summarizes the results of a survey about prenatal culture-processing
practices in 2003, which indicated that, although adherence to GBS isolation
procedures was high, opportunities exist to improve implementation of recommendations
related to antimicrobial susceptibility testing and GBS bacteriuria.

of Perinatal Group B Streptococcal Disease: Revised Guidelines from

Data collected after the issuance of the 1996 guidelines prompted reevaluation
of prevention strategies. The new recommendations are based on available evidence
and expert opinion where sufficient evidence was lacking. Although many of
the recommendations in the 2002 guidelines are the same as those in 1996, they
include some key changes: 1) Recommendation of universal prenatal screening
for vaginal and rectal GBS colonization of all pregnant women at 35-37 weeks'
gestation; 2) Updated prophylaxis regimens for women with penicillin allergy;
3) Detailed instruction on prenatal specimen collection and expanded methods
of GBS culture processing; 4) Recommendation against routine intrapartum antibiotic
prophylaxis for GBS-colonized women undergoing planned cesarean deliveries
who have not begun labor or had rupture of membranes; 5) A suggested algorithm
for management of patients with threatened preterm delivery; and 6) An updated
algorithm for management of newborns exposed to intrapartum antibiotic prophylaxis.
Group B streptococcus (GBS) remains a leading cause of serious neonatal infection
despite great progress in perinatal GBS disease prevention in the 1990s.
Prenatal Screening
is Most Effective Strategy to Prevent Newborn Strep B Infections (Press
Release)

Routine screening for group B streptococcus late in pregnancy is the most effective
way to prevent transmission of the bacteria from mother to child during delivery.
The data were published in the July 25, 2002 issue of the New England Journal
of Medicine (NEJM). Guidelines issued in 1996 to prevent transmission of the
bacteria from mother to newborn recommend that health care providers use one
of two methods. The new data show that the prenatal screening method was more
than 50 percent more effective in preventing transmission than the clinical
risk factor method. The new guidelines will be published in the CDC Morbidity
and Mortality Weekly Report. Group B streptococcal disease remains a leading
infectious cause of illness and death among newborns in the United States,
resulting in approximately 1,600 illnesses and 80 deaths each year.
