BAG-Campylo-CaCo & Provider - Epidemiology of campylobacteriosis in Switzerland

Campylobacter spp. are the most frequently recorded foodborne, bacterial infections in the Swiss National Notification System for Infectious Diseases (NNSID). The overall goal of the project is to get a better understanding of foodborne diseases in Switzerland with a special emphasis on campylobacteriosis. The project aim is fourfold:


  1. To develop a concept for investigating the epidemiology of campylobacteriosis in Switzerland
  2. To identify determinants of the campylobacteriosis winter peak observed in Switzerland
  3. To describe general morbidity patterns and how campylobacteriosis presents in the (laboratory-confirmed) patient
  4. To describe how physicians diagnose, treat and manage acute gastroenteritis and campylobacteriosis patients in general practice

The concept is developed based on a literature review and an analysis of campylobacteriosis notification data. Then, a prospective case control study on risk factors for campylobacteriosis over Christmas and New Year is conducted. Furthermore, the study includes a description of the perceived illness experience of campylobacteriosis patients. Cases are laboratory-confirmed campylobacteriosis patients registered in the NNSID. Controls are selected from a representative sample of the general population, drawn by the Federal Statistical Office. Finally, a qualitative assessment among primary care physicians covering all Swiss regions will be conducted to investigate their approach to manage acute gastroenteritis and campylobacteriosis patients.
