Campylobacteriosis is the most commonly reported gastrointestinal disease in the EU/EEA. In 2021, 30 EU/EEA countries reported 129 960 confirmed cases of campylobacteriosis, with Liechtenstein reporting cases for the first time. The overall EU/EEA notification rate was 44.5 cases per 100 000 population.

The campylobacteriosis notification rate was highest in children under five years of age. Campylobacteriosis notification rates in the five years preceding the COVID-19 pandemic have been stable. After a significant decline in cases in 2020, primarily as a consequence of the pandemic, case numbers increased by 5.6% in 2021.

Campylobacteriosis shows clear seasonality, with a sharp peak of cases in the summer months and a
smaller peak at the beginning of the year.
