Listeriosis | MedTrace

Disease Profile

Listeriosis is a foodborne bacterial infection caused by Listeria monocytogenes that can present with invasive disease such as sepsis or meningitis, especially in high-risk populations. Severe outcomes include hospitalization, fetal loss in pregnancy-associated cases, and notable case-fatality risk.

Category: foodborne bacterial infectious disease
Prevalence: U.S. annual incidence is about 0.24 laboratory-confirmed cases per 100,000 population, with roughly 1,250 estimated cases per year including under-detection.
