Increasing Incidence of Invasive Group B Streptococcal Infections in Nonpregnant Adults

Findings suggest that obesity and diabetes are the most common risk factors.

Group B Streptococcus (GBS) is most commonly associated with infection in pregnant women and neonates, but it has been associated with cancer and other chronic diseases in nonpregnant adults.

Using the Active Bacterial Core surveillance (ABCs) network, researchers studied trends in the epidemiology of GBS from 2008 to 2016 in nonpregnant adults. Overall, 21,250 cases were identified, with an increase over the study period of 8.1 to 10.9 cases per 100,000 people. Older age was a significant risk factor, with rates of almost 25/100,000 for those between the ages 65 and 79 versus <5/100,000 for those 18 to 39. More than 90% of patients had underlying medical conditions, and 53.8% and 53.4% had obesity and diabetes, respectively. Almost all pati…
