What kinds of illnesses does group B strep cause?
In newborns, group B strep is the most common cause of sepsis (infection of the bloodstream) and meningitis (infection of the lining and fluid surrounding the brain) and a common cause of pneumonia. Group B strep disease in newborns usually occurs in the first week of life (“early- onset”). Babies can also get a slightly less serious “late-onset” form of group B strep disease that develops a week to a few months after birth. In adults, group B strep usually causes no symptoms. However, in rare cases, it can lead to serious bloodstream infections, urinary tract infections, skin infections, and pneumonia, especially in people with weakened immune systems and other health problems, such as diabetes. How do people get infected with group B strep? Group B strep bacteria are different from many other types of bacteria that can cause disease. People can be “colonized” with group B strep. This means that they carry the bacteria in their bodies but are not infected and do not become sick. Adult
