Overview

Immunosuppressed patients, neonates, pregnant women and elderly patients are at a higher risk for listeriosis. are more likely to develop serious illness such as life-threatening bacteremia and meningoencephalitis.[1]

Risk Factors

Pregnant Women

About one in seven (14%) cases of listeriosis occurs during pregnancy. Pregnant women are about 10 times more likely than the general population to be infected. Pregnant Hispanic women are about 24 times more likely than the general population to get listeriosis.[2]

Older Adults

More than half (58%) of Listeria infections occur among adults 65 and older. Adults 65 years and older are about 4 times more likely than the general population to be infected.[2]

People with Weakened Immune Systems

Individuals within this group also have a higher risk for infection due to underlying medical conditions such as cancer and immunosuppresive therapy (i.e., steroids, chemotherapy, radiation), liver or kidney disease, diabetes, alcoholism, and HIV/AIDS. AIDS patients are almost 300 times more likely to get listeriosis than people with normal immune systems.

Newborn Babies

Newborn babies suffer the most serious effects of listeriosis in pregnancy.
