    • Pregnant people, adults 65 years or older, and people with weakened immune systems are at higher risk for severe illness.
    • Pregnant people typically experience only fever, fatigue, and muscle aches. However, Listeria infections during pregnancy can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.
