Using one health and participatory epidemiology to assess impacts of anthrax on the human-animal interface in rural Uganda
- 1. Using One Health and Participatory Epidemiology to Assess Impacts of Anthrax on the Human-Animal Interface in Rural Uganda Jeanne L Coffin, MS Fred Monje, DVM Grace Asiimwe-Karimu, DVM PENAPH First Technical Workshop Dec. 11-13 2012, Chiang Mai, Thailand
- 2. Summary Slide Conservation Medicine and Participatory Methods Systematic Review Applying Participatory Epidemiology (PE) to Anthrax in Uganda Results and Discussion Management Proposal
- 3. Background Conservation Medicine & A Systematic Review of Participatory Literature
- 4. Conservation Medicine Conservation medicine is an emerging, interdisciplinary field that studies the relationship between human and animal health and environmental conditions, or ecosystem health. It seeks to apply that knowledge to better the management of One Health or Ecohealth challenges. Case Study for a 1 year Masters in Conservation Medicine.
- 5. Systematic Review of Literature Standard search and coding 13 papers met the exclusionary criteria Scoring of each accepted paper counteracting bias level of participation reached as in Pretty 1994 quality of study design execution reporting
- 6. Results All but one study made adequate efforts to counteract bias need more integration with quantitative methods No paper reached the highest level5 Reporting and evaluation was highly variable feed back to participants often not mentioned Study design was not clearly described example outlines or questions needed
- 7. Learning from the Literature Technical pitfalls to avoid Slippery definitions Avoid bias use rigorous sampling and triangulation cross-check with conventional methodologies plan adequately Evaluation and reporting Reporting as transparently as possible Pursuing follow up faithfully is important
- 8. In the Field
- 9. Anthrax in Uganda Western Uganda is mixed livestock and banana farming Sporadic ongoing anthrax (B. anthracis) outbreaks wildlife in 2005 in Queen Elisabeth National Park3 and again in 2010 cattle and people in 2011 in Sheema District6
- 10. Main Aims Understand the context surrounding the ongoing anthrax outbreaks Propose a management plan Gain on the ground experience and practice with participatory epidemiology methods
- 11. Specific Objectives Assess the impact of anthrax on humans and domestic animals around QENP relative to other local diseases Assess knowledge of zoonoses Assess knowledge of wildlife role in anthrax life cycle Understand attitudes about anthrax, related veterinary services, and wildlife
- 12. Study Design Study Partners AFENET fellows with Makerere University staff internship at Uganda Wildlife Authority In the field in late July of 2012 pilot study PE4 compared with conventional questionnaires
- 13. Techniques Used Formal questionnaires Informal Interviews semi-structured Focus groups semi-structured interview participatory mapping simple and comparative ranking proportional piling matrix scoring
- 14. Sampling Two districts where anthrax outbreaks had occurred (purposive) two subcounties – one adjacent to anthrax outbreaks, one further away (purposive) 1-2 villages in each subcounty (convenience) 2-3 focus groups in each village (convenience) 5+ questionnaires in each village (76 total)
- 15. Study Locations
- 16. Second Location
- 17. Collaborative Challenges short timeframe of program institutional communication Participatory Epidemiology time constraints standardization gave way to flexibility data management bias introduced by previous studies participant frustration with previous lack of feedback The Bugs
- 18. Results Anthrax vs. other diseases Not always top 3 Other diseases at top: brucellosis, tick diseases, trypanosomiasis Impact of disease varied Non-disease issues also very important Disease impact varied by experience Economic and social impacts very important
- 19. Results Color Key: Pink x > 50% Purple 49% > x > 35% Yellow 34% > x > 20% White x < 19% Note frequency of economic impacts chosen in the top three listed here by disease. Anthrax in top 3 in 3/5 focus groups in Kasese, and in1/6 in Sheema.
- 20. Results
- 21. Knowledge and Attitudes Zoonoses Knowledge of zoonosis varies Sometimes choose not to treat carcasses appropriately – cutting their losses Wildlife role well known near park, unknown elsewhere Frequent dissatisfaction with availability of veterinary services Lack of veterinarians, medications, vaccines Quarantines are unpopular
- 22. Management Proposal Widen survey – beyond reported case areas follow PE trail, wide surveys of environmental factors Include soil biology and chemistry amoebas1 Domestic canine seroprevalence2 Field or local tests these could be “immediate” feedback for participants Use this data to tailor vaccination and education programs to high risk areas.
- 23. Further Study, or Surveillance? Research Link to public service organizations Scientific or mixed funding Surveillance, either sporadic or regular Some form of governmental support AFENET, work with the Ugandan PE network Non-profits Appropriate technology
- 24. Recap/Conclusion PE and other participatory methods have room to grow PE could enhance and inform regular anthrax management in Uganda Frequency of outbreaks might be reduced if targeted vaccination and education were implemented.
