The Highly Pathogenic Avian Influenza virus H5N1 is still present in some of the poorest areas of the world as South-east Asia where the disease occurred on a regular basis in human and poultry. Early detection of the disease in poultry population is the most efficient method to avoid the spread of the virus to human. In poor rural communities of developing countries, such as Cambodia, this disease detection is often based on volunteer case reporting by farmers. However this surveillance method carries challenges when applied in difficult socioeconomic environments: low density of health facilities, poor communication systems, weak awareness of population, distrust on governmental authorities and lack of qualified staff. We have in this thesis conceived and applied new methods for the evaluation, the design or the improvement of passive surveillance in order to propose innovative methods to increase the involvement of rural communities in the reporting of zoonotic diseases.
The international community and governmental organizations are actively calling for the implementation of One Health (OH) surveillance systems to target health hazards that involve humans, animals, and their environment. In our view, the main characteristic of a OH surveillance system is the collaboration across institutions and disciplines operating within the different sectors to plan, coordinate, and implement the surveillance process. However, the multisectoral organizational models and possible collaborative modalities implemented throughout the surveillance process are multi-fold and depend on the objective and context of the surveillance. The purpose of this study is to define a matrix to evaluate the quality and appropriateness of multisectoral collaboration through an in-depth analysis of its organization, implementation, and functions. We developed a first list of evaluation attributes based on (i) the characteristics of the organization, implementation, and functionality of multisectoral surveillance systems; and (ii) the existing attributes for the evaluation of health surveillance systems and OH initiatives. These attributes were submitted to two rounds of expert-opinion elicitation for review and validation. The final list of attributes consisted of 23 organizational attributes and 9 functional attributes, to which 3 organizational indexes were added measuring the overall organization of collaboration. We then defined 75 criteria to evaluate the level of satisfaction for the attributes and indexes. The criteria were scored following a four-tiered scoring grid. Graphical representations allowed for an easy overview of the evaluation results for both attributes and indexes. This evaluation matrix is the first to allow an in-depth analysis of collaboration in a multisectoral surveillance system and is the preliminary step toward the creation of a fully standalone tool for the evaluation of collaboration. After its practical application and adaptability to different contexts are field-tested, this tool could be very useful in identifying the strengths and weaknesses of collaboration occurring in a multisectoral surveillance system.
In response to the global call to mitigate risks associated with antimicrobial resistance (AMR), new regulations on the access and use of veterinary antibiotics are currently being developed by the Lao government. This study aims to explore how the implementation of these new regulations might effectively reduce and adapt the sale, distribution and use of veterinary antibiotics in Lao PDR. To this end, we used the theory of change, framing the AMR issue within the context of the stakeholders involved in the veterinary antibiotics supply chain. Qualitative and quantitative methods were used to collect data, based on questionnaires (n=36 antibiotic suppliers, n=96 chicken farmers, n=96 pig farmers), and participatory tools such as a workshop (n=10 participants), semi-structured interviews (n=20), and focus group discussions (n=7 participants). The stakeholders' understanding of the AMR issue and potential challenges related to the implementation of new regulations regarding access and use of antibiotics, were also investigated. We mapped the veterinary antibiotic supply chain in Lao PDR, and analysed the roles and interactions of its stakeholders. Twenty-three stakeholders representing the private and the public sectors were identified. Many informal and formal links connected these stakeholder within this supply chain. The lack of veterinarian-farmer interaction and the evolving nature of the veterinary antibiotics supply chain accentuated the challenges of achieving behaviour change through regulations. Most of the antibiotics found on farms were categorized by the World Health Organisation's as critically important antibiotics used in human medicine. We argue that AMR risk mitigation strategy requires dialogue and engagement between private and public sectors stakeholders, involved in the importation, distribution, sale and use of veterinary antibiotics. This study further highlighted that AMR is a complex adaptive challenge requiring multi-sectoral approach. We believed that a sustainable approach to reduce and adapt veterinary antibiotics use should be prepared in collaboration with stakeholders from private and public sectors identified in this study, in addition to the new regulations. This collaboration should start with the co-construction of a common understanding of AMR issue and of the objectives of new regulations.

Purpose: In Cambodia, Village Animal Health Workers (VAHW) have been trained by NGOs or by the government to provide animal health services (treatment, husbandry advice, vaccination) to their communities' farmers. This system is characterised by a high variability of skills because of non-harmonised training plans, poor sustainability with a large number of VAHWs dropping their activities after five years and no harmonised tools for their evaluation. The objective of the study was to assess the work skills of VAHW. Methods: We applied a scoring grid composed of five categories (sustainability, treatment, production, vaccination, reporting). Linked to several evaluation criteria, specific questions were defined to assess if the criteria were fulfilled by the VAHW. An additional questionnaire, with 31 explanatory variables, was developed in order to collect data about factors that could influence the VAHW's score. The study was implemented in three provinces bordering Vietnam (Kampong Cham, Prey Veng and Takeo). A total of 367 villages were selected using a proportional random sampling, g method. We applied a multivariable linear regression model to determine factors associated with high scores for the VAHW evaluation. Results: In the population studied, 23% of the villages did not have a VAHW. According to our scoring system, 23.6% of the VAHW interviewed were in a situation of inactivity. From our multivariable analysis, six factors were significantly associated with a high score in the evaluation of the VAHW once they were active: selecting a VAHW from a village with at least 100 heads of cattle, using practical activities during training, having a training duration longer than 30 days, organising refresher courses, being a member of association and having regular contact with the district veterinarian. Conclusions: These results demonstrate the need of constant networking activities in the surveillance system to ensure that field staffs do not feel isolated. Relevance: Some of these findings could be used as a prerequisite for continued participation in refresher training activities done by the Cambodian government. (Texte intégral)
This study aims to explore the farmers' perceptions of FMD vaccination using a reflexive research method called Q methodology. A structured sample was composed including 46 farmers selected according to gender, farming experience, level of education and production type. Statements relevant to the farmers' perceptions of and attitudes towards FMD vaccination, related to confidence, logistics, costs and impacts of vaccination, were developed. Results were analysed by principal component analysis, using R version 3.1.2. Three distinct discourses ""Believe"", ""Confidence"", ""Challenge"", representing common perceptions among farmers and accounting for 57.3 % of the variance, were identified. Consensus points were found such as: the feeling of being more secure after FMD vaccination campaigns; the fact that farmers take vaccination decisions themselves without being influenced by other stakeholders; the opinion that FMD vaccination is cheaper than the costs of treating a sick animal; and that vaccines provided by governmental authorities are of good quality. Part of the studied population did not consider vaccination to be the first choice strategy in prevention. This raises the question of how to improve the active participation of famers in the FMD vaccine strategy. Regular awareness raising is an important tool to foster active participation and to maintain the farmers' motivation to vaccinate.
This study aims to explore the farmers' perceptions of foot-and-mouth disease (FMD) vaccination using a reflexive research method called Q methodology. A structured sample was composed of 46 farmers selected according to gender, farming experience, level of education, and production type. Statements relevant to the farmers' perceptions of and attitudes toward FMD vaccination, related to confidence, logistics, costs, and impacts of vaccination were developed. Results were analyzed by principal component analysis and factor analysis. The influence of demographics and characterized variables on the respondent's contribution to each factor was also tested. Regarding the different beliefs and behavior toward FMD vaccination, the common perceptions held by Vietnamese cattle and pig farmers were divided into three discourses named Confidence (24 subjects), Belief (12 subjects), and Challenge (6 subjects). The identified discourses represented 57.3% of the variances. Consensus points were found, such as the feeling of being more secure after FMD vaccination campaigns; the fact that farmers take vaccination decisions themselves without being influenced by other stakeholders; the opinion that FMD vaccination is cheaper than the costs of treating a sick animal; and that vaccines provided by governmental authorities are of high quality. Part of the studied population did not consider vaccination to be the first choice strategy in prevention. This raises the question of how to improve the active participation of farmers in the FMD vaccine strategy. Taking into consideration farmers' perceptions can help to implement feasible vaccination strategies at the local level.

Purpose Since 2006, Vietnam has implemented mass vaccination against foot and mouth disease (FMD) for all cattle and buffaloes within specific targeted areas. However this strategy is still facing many logistical and economic constraints. This study aimed to explore South-Vietnamese farmers' subjectivities regarding FMD vaccination using a reflexive research method called Q methodology. This method allowed us to identify groups of farmers who shared similar viewpoints. Methods A structured sample of 46 farmers in Tay Ninh province was chosen. These 46 respondents were distinguished in socio - economic variables such as gender, experience level, education level and production's type. Statements relevant to farmers' attitude and perception toward FMD vaccination have been developed from previous groups and individual interviews, to produce a Q-set of 46 items. They covered 4 themes regarding vaccination: confidence, logistic, cost and impacts. Q method results were analyzed performing principal component analysis (PCA) using R version 3.1.2. Results Three factors, representing common perceptions between farmers and accounting together for 57,3 % of the variance were selected. Several consensus points were found across the factors: they feeling more secure after vaccination campaign; they strongly thinking that a good vaccination practice will make their animal have a good protection; they taking vaccination decision themselves without influenced from other actors; vaccination is cheaper than treatment cost; vaccines given by governmental authorities are of good quality. However there were several points of disagreement between factors: for some farmers (factor 3) if the housing and feeding conditions are good, they don't need to vaccinate their animals every year; the preferred type of vaccine (individually or multi dose) will depend between factors. Conclusions These outputs provided critical elements on the acceptability of FMD vaccination programs by farmers in Vietnam and allowed some recommendations on how to improve their involvement. Further researches are still required to understand and combine viewpoints of other actors involved in the vaccination campaign. (Texte intégral)
Background The international community strongly advocates the implementation of multi-sectoral surveillance policies for an effective approach to antibiotic resistance, in line with the One Health concept. To comply with these international recommendations, the Vietnamese government has issued an inter-ministerial surveillance strategy for antibiotic resistance, including an integrated surveillance system. However, one may question the ability and willingness of surveillance stakeholders to implement the collaborations required. To assess the feasibility of operationalising this strategy within the national context, we explored the role of key stakeholders in the strategy, as well as their abilities to comply with it. Methods We conducted a qualitative approach based on an iterative stakeholder mapping and analysis, in three distinct steps: (1) a description of the structure of the national surveillance strategy (literature review, key informant interviews); (2) an analysis of the key stakeholders' positions regarding the strategy (semi-structured interviews); (3) the identification of factors influencing the operationalisation of the collaborative surveillance strategy (comparison of data collected at the first and second steps). Results The mapping of the surveillance system, as well as the characterisation of key stakeholders according to organisational and functional attributes, underlined that inter-sectoral surveillance initiatives do exist, but that the organisation of the national surveillance system remains highly silo-oriented. Based on stakeholder perspectives, we identified seven factors that may influence the implementation of the One Health strategy at national level: governance and operational frameworks, divergence of institutional cultures, level of knowledge, technical capacities, allocation of resources, conflicting commercial interests and influence of international partners. Conclusions The study suggests that the operationalisation of the collaborative surveillance strategy requires the ...

Conclusions The study suggests that the operationalisation of the collaborative surveillance strategy requires the full adhesion of stakeholders and the provision of appropriate resources. Based on these findings, we have proposed a guidance framework together with recommendations to move towards a more suitable governance and operational model for One Health surveillance of antibiotic resistance in Vietnam. To lever and promote successful inter-sectoral collaboration, a participatory "learning by doing" process could be applied to guide, frame and mentor stakeholders through the identification of appropriate levels of collaboration, depending on the expected positive impacts on the value of surveillance.
