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
Summary Slide Conservation Medicine and Participatory Methods Systematic Review Applying Participatory Epidemiology (PE) to Anthrax in Uganda Results and Discussion Management Proposal
Background Conservation Medicine & A Systematic Review of Participatory Literature
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.
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
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
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
In the Field
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
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
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
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
Techniques Used
Formal questionnaires Informal Interviews
semi-structured Focus groups
semi-structured interview participatory mapping simple and comparative ranking proportional piling matrix scoring
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)
Study Locations
Second Location
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
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
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.
Results
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
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.
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
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.
