MedicalResearch.com: What is the background for this study?
Response: Group B Streptococcus (GBS) is a leading cause of serious illness such as meningitis and sepsis in infants. Among infants, there are two main types of GBS disease. Early-onset GBS disease occurs during the first week of life and late-onset GBS disease occurs from the first week through three months of life. Rates of early-onset disease in the United States have decreased significantly since the 1990s through widespread implementation of intrapartum antibiotic prophylaxis (IAP) guidelines. However, IAP does not prevent late-onset disease. Maternal immunization represents a nonantibiotic strategy to prevent both early and late-onset disease. Multivalent polysaccharide-protein conjugate vaccines are under development against GBS capsular types, with candidate vaccines in phase I and II trials.
Active Bacterial Core surveillance (ABCs) conducts active surveillance for early and late-onset GBS disease among infants in select counties of 10 states, covering about 10% of live births across the United States. We analyzed data from early and late-onset GBS cases identified from ABCs between 2006 and 2015 to describe their epidemiology, incidence trends, and associated strain characteristics.
