Group B Streptococcal Disease (GBS)


Group B Streptococcus (GBS) is a bacterium that causes illness in newborn babies, pregnant women, the elderly, and adults with other illnesses, such as diabetes or liver disease. GBS is the most common cause of life-threatening infections in newborns.

Oregon's Public Health Division conducts surveillance for GBS in the Portland tri-county area (Multnomah, Clackamas and Washington counties).

Prevent Group B Strep App
Revised Guidelines for the Prevention of Perinatal Group B Streptococcal (GBS) Disease were published in 2010. A new “Prevent Group B Strep” app has been developed for healthcare providers. The app was developed in collaboration with and endorsed by the American College of Obstetricians and Gynecologists (ACOG), American Academy of Pediatrics (AAP), American College of Nurse-Midwives (ACNM), and American Academy of Family Physicians (AAFP). The app provides patient-specific and scenario-specific guidance in accordance with the new 2010 guidelines.
