Environmental Epidemiology in Latin America (2014-2015)

The objective for this Bass Connections project team was to further our understanding of epidemiological risk factors associated with endemic infectious diseases as well as the emergence of chronic diseases in the Madre de Dios Region of the southern Peruvian Amazon. This project was part of a multiyear study to understand population and environment dynamics occurring along both a newly developed highway and a watershed undergoing heavy gold mining operations. These large-scale development changes interact with household livelihood choices to alter the risk profile of families and individuals living in the region. In addition to these developments, a recent land concession for oil exploration has been granted, centrally located in the study site. Similarly to the rapid changes caused by highway construction and ongoing gold mining, oil development has the potential to have a lasting and wide impact on social, environmental and health characteristics of the region. 

Therefore, this Bass Connections project team continued the work of engaging and educating communities and families regarding good health practices; conducting research to better understand risk factors for infectious and chronic diseases as well as toxicological exposure (e.g., mercury, arsenic, selenium, mostly due to gold mining); and improving our understanding of biogeochemical cycling (e.g., in air, soil and water) and the bioaccumulation of toxic metals in food (focusing on mercury). Team members were trained in epidemiology, hydrology, land use/land cover change (remote sensing), toxicology, nutrition and biogeochemical cycling. Activities included a seven-month training program in North Carolina (November-May), followed by 8-10 weeks in the Peruvian Amazon. Team members spent the summer researching vector-borne diseases and the health impacts of mercury exposure. The team also partnered with the Peruvian Ministry of Health to give presentations to children on nutrition, dental hygiene and handwashing.
