Pregnant women and people who have weak immune systems are at highest risk of contracting a listeria infection.

Pregnant women and their babies

Pregnant women are significantly more susceptible to listeria infections than are other healthy adults. Although a listeria infection may cause only a mild illness in the mother, consequences for the baby may include:

  • Miscarriage
  • Stillbirth
  • Premature birth
  • A potentially fatal infection after birth

People who have weak immune systems

This category includes people who:

  • Are older than 65
  • Have AIDS
  • Are undergoing chemotherapy
  • Have diabetes or kidney disease
  • Take high-dose prednisone or certain rheumatoid arthritis drugs
  • Take medications to block rejection of a transplanted organ
