Complications
By Mayo Clinic staffMost listeria infections are so mild they may go unnoticed. However, in some cases, a listeria infection can lead to life-threatening complications — including:
- A generalized blood infection (septicemia)
- Inflammation of the membranes and fluid surrounding the brain (meningitis)
Complications of a listeria infection may be most severe for an unborn baby. Early in pregnancy, a listeria infection may lead to miscarriage. Later in pregnancy, a listeria infection may lead to stillbirth, premature birth or a potentially fatal infection in the baby after birth — even if the mother becomes only mildly ill.
Infants who survive a listeria infection may experience long-term neurological damage and delayed development.
Adults over 60 can also be seriously affected by a listeria infection, and death rates may be as high as 10 to 20 percent for this age group.
