Rate My Professor Nienke Hagedoorn

Relocating to New Zealand in 2022, she initially worked as a postdoctoral research fellow in the Departments of Primary Care and Paediatrics at the University of Otago, focusing on vaccine-preventable diseases and community antibiotic consumption. Since October 2022, she has contributed to the Centre for International Health, undertaking systematic reviews and meta-analyses on typhoid fever epidemiology under Professor John Crump. Her research interests center on clinical epidemiology of infectious diseases, invasive bacterial infections—including typhoid fever, non-typhoidal Salmonella, and leptospirosis—immunizations, and optimizing antibiotic prescriptions, with an emphasis on low- and middle-income countries. Notable publications include: Murthy et al. (2025) "Global typhoid fever incidence: An updated systematic review with meta-analysis" in The Lancet Infectious Diseases; Hagedoorn et al. (2024) "Global distribution of Leptospira serovar isolations and detections from animal host species: A systematic review and online database" in Tropical Medicine & International Health; Hagedoorn et al. (2024) "Prevalence and distribution of non-typhoidal Salmonella enterica serogroups and serovars isolated from normally sterile sites: A global systematic review" in Epidemiology & Infection; and Hagedoorn et al. (2023) "Comparison of clinical prediction rules in pre-school aged children with septic hip arthritis due to different pathogens" in Journal of Pediatric Orthopaedics. Through collaborations in international consortia such as VACC-iNTS and PERFORM, her work advances global public health strategies.
