Methodology Notes

A laboratory-confirmed case of group B Streptococcus is defined as either the isolation of group B Streptococcus from cerebrospinal fluid or a positive culture of group B Streptococcus from a different normally sterile site (blood, pleural fluid, etc.) in a newborn aged 0 to 6 days in the surveillance area.

Rates were calculated using live birth estimates for 2009. Missing race data was multiply imputed and surveillance rates were standardized to the racial distribution of the live birth estimates using vital statistics data from the CDC National Center for Health Statistics (NCHS).
