Ongoing High Incidence and Case-Fatality Rates for Invasive Listeriosis, Germany, 2010-2019

We used 10 years of surveillance data to describe listeriosis frequency in Germany. Altogether, 5,576 cases were reported, 91% not pregnancy associated; case counts increased over time. Case-fatality rate was 13% in non-pregnancy-associated cases, most in adults >= 65 years of age. Detecting, investigating, and ending outbreaks might have the greatest effect on incidence.
