Event description

Description

Typhoid fever is a serious disease threat in the South Pacific region, with Fiji reporting the highest annual number of cases, yet risk factors in this setting have been poorly studied. While localised behaviours have dominated perspectives on typhoid transmission, interactions between distal ecological conditions, conditions of the residential environment and localised behaviour deserve greater attention for their potential to influence transmission. This presentation demonstrates a nested approach to typhoid epidemiology utilising geospatial, case-control, microbiological, physicochemical and observational methodologies to explore how regional, river basin, residential, socio-cultural and behavioural subsystems influence the risk of typhoid transmission in Central Division, Fiji. Significant risk factors are synthesized within and across nested subsystems and several intervention scenarios are explored using a Bayesian Network approach. This study demonstrates how a nested environmental approach to studying and interrupting waterborne disease transmission extends the testing of causal assumptions beyond the domestic domain, enhances traditional case-control approaches and provides evidence for multi-scale interventions on drivers of disease and environmental degradation.


About Dr Aaron Jenkins

Dr Aaron Jenkins is the inaugural Research Fellow in Planetary Health research with the Sydney School of Public Health, Marie Bashir Institute for Infectious Diseases and Biosecurity, and Edith Cowan University’s Centre for Ecosystem Management. He has highly regarded expertise in crosscutting development themes including integrated conservation and development, wetland management for health, nutrition and climate change mitigation and waterborne disease management. This expertise stems from 20 years of professional experience in international development working with international, regional agencies, governments, NGOs, donors, universities and communities across Asia-Pacific. He has high-level engagement in international and regional affairs, and is an elected board member of the International Association of Ecology & Health. His current research focus explores the socio-ecological determinants of waterborne diseases.
