Describing nearly two decades of Chagas disease in Germany and the lessons learned: a retrospective study on screening, detection, diagnosis, and treatment of Trypanosoma cruzi infection from 2000 – 2018 Jessica Michelle Guggenbühl Noller1,2†, Guenter Froeschl1,2*† , Philip Eisermann3, Johannes Jochum4, Stefanie Theuring5, Ingrid Reiter-Owona6, Alfred Lennart Bissinger7, Michael Hoelscher1,8, Abhishek Bakuli1, Franz-Josef Falkner von Sonnenburg1ˆ, Camilla Rothe1, Gisela Bretzel1, Pedro Albajar-Viñas9, Lise Grout9 and Michael Pritsch1

Abstract Background: The highly complex and largely neglected Chagas disease (CD) has become a global health problem due to population movements between Latin America and non-endemic countries, as well as non-vectorial transmission routes. Data on CD testing and treatment from routine patient care in Germany of almost two decades was collected and analysed. Methods: German laboratories offering diagnostics for chronic Trypanosoma cruzi (T. cruzi) infection in routine patient care were identified. All retrievable data on tests performed during the years of 2000–2018 were analysed. Additional clinical information regarding patients diagnosed with CD was collected through questionnaires.
