by Schulte S




Group B streptococcal (GBS) disease is a bacterial infection.
GBS can cause illness in newborn babies, pregnant women, the elderly, and adults with other chronic medical conditions, such as diabetes or liver disease. In newborns, it is the most common cause of a blood infection called sepsis and of meningitis, which is an infection of the fluid and lining surrounding the brain.
This following information covers GBS in pregnant women and their babies.

Risk Factors

Factors that increase the risk of a baby having GBS include the following:
