One health outlook最新文献

Introduction: Multifactorial determinants of vector presence, distribution and ability of transmitting diseases, demand holistic approaches that consider eco-biosocial factors, such as One Health (OH), and engage institutions and communities to reduce vulnerability to vector-borne diseases (VBDs). Although the importance of multisectoral, multilevel and multigroup collaboration for prevention and preparedness to VBDs has been promoted by international guidance, evidence about practical experiences adopting a OH approach needs to be gathered and enabling factors for a successful governance highlighted.

Methods: This study included a rapid literature review coupled with a stakeholder consultation process.

Results: The peer-reviewed literature search identified 1674 articles and 13 articles were finally included in the review. The collaboration and coordination of different sectors and stakeholders allowed to focus resources, and share knowledge and perspectives. To support coordination and collaboration among the stakeholders synergistic interaction mechanisms were created, such as working groups and committees, and connection agents emerged as the main link between institution and communities. These synergies allowed to target the multidimensional drivers of VBDs, supported transversal capacity building and an holistic monitoring evaluation framework, and improved effectiveness and sustainability of the interventions.

Conclusion: A OH model highlighting enabling factors for multisectoral, multilevel and multigroup interventions for VBDs prevention and preparedness was developed to support decision-makers and key stakeholders to deal with a OH governance.

In the post-COVID-19 era, stakeholders, including policymakers, funders, and the public, are increasingly seeking for a cross-sectoral systems-based approach to health risks extending beyond conventional measures. Anchored on three health pillars -human, animal, and environmental- One Health offers a promising framework to effectively address this demand. While some nations have already implemented national One Health strategic plans, European countries, in general, are lagging behind the global agenda. On 22 February 2024, an initiative was launched in Austria toward addressing this gap, bringing together multiple sectors and disciplines, marking the initial step in creating a national One Health network. The workshop emphasized the importance of enhancing One Health education and addressed key topics, such as incorporating the environmental pillar of One Health as well as socio-economic and cultural drivers to further our understanding of outbreaks, and establishing trusted communication channels, including data sharing, between disciplines and sectors. Identified challenges encompassed the need for more funding of transdisciplinary research. Opportunities for advancement include initiating local One Health projects and showcasing their positive impacts. Moving forward, efforts will focus on establishing a mature and globally connected One Health framework in Austria and supporting the integration of One Health aspects into education curricula, research programs, and policies.

Severe fever with thrombocytopenia syndrome (SFTS), a tick-borne disease caused by Dabie bandavirus (SFTSV) is an emerging infectious disease of substantial concern in East Asia. In 2019, Ongkittikul S et al. reported the first case of SFTS in Thailand. Our report describes a One Health investigation of SFTS zoonosis examining the index case and suspected animal reservoirs using real-time RT-PCR and immunoassays. We add to the report on the first confirmed case of SFTSV infection in a human in Thailand by conducting a limited but informative One Health surveillance study. Dogs and cats tested positive for SFTSV antibody using IgG ELISA. We conclude that domestic dogs and cats might serve as potential reservoirs for SFTSV spread due to their closer proximity to the index case than other non-domestic animals. Notably, we did not detect SFTSV in synanthropic cats or dogs-nor did we detect SFTSV in Rhipicephalus sanguineus ticks-using RT-PCR. We propose that One Health investigations coupling genomic and serologic assays in response to new SFTS cases could play a pivotal role in preventing and managing SFTS among humans and animals in East Asia. As such, we are establishing a collaborative response to SFTS in Thailand through human outbreak investigations that align with principles of One Health, through environmental surveys and animal RT-PCR and immunoassays. Our investigation highlights the importance of coupling RT-PCR with seroprevalence assays as principal elements of One Health surveillance for SFTS in order to shed light on potential animal reservoirs and track emerging zoonosis.

Introduction: Around 75% of (re)emerging infections are of zoonotic origins. The risk of zoonotic transmission in Mozambique is high because approximately 81% of the country's labor force is involved with agriculture, which represents a vulnerability for more frequent human-animal interaction and risk of spillover events. A One Health Zoonotic Disease Prioritization (OHZDP) workshop was conducted in Mozambique to facilitate coordination and collaboration within and across sectors to prevent, detect, and respond to zoonotic disease threats. Based on the success of this integrated workshop, the stakeholders developed actions whose results have a great impact on animal welfare, environment and improving public health.

Methods: In 2018, representatives from Mozambique's human, animal, and environmental sectors from government, universities, research institutions and partners used US CDC's OHZDP Process to prioritize endemic and emerging zoonotic diseases of greatest national concern and develop recommendations and key interventions needed to advance One Health in Mozambique. After the OHZDP workshop, the Mozambique One Health Secretariat used a theory of change methodology to identify activities for implementation from the recommendations of the OHZDP workshop. Since the OHZDP workshop, the Secretariat has monitored progress of activities annually.

Results: Mozambique's priority zoonotic diseases are rabies, zoonotic tuberculosis, salmonellosis, zoonotic avian influenza, trypanosomiasis, brucellosis, and Crimean-Congo hemorrhagic fever. One Health recommendations and interventions to address the priority zoonotic diseases focused on One Health collaboration, communication, and coordination; laboratory; surveillance; preparedness and response; prevention; workforce development; and research. After the OHZDP workshop, Mozambique established One Health coordination mechanisms, developed training courses for surveillance, laboratory diagnosis, outbreak investigation, and preparedness and response for the priority zoonotic diseases, conducted joint research, and developed plans.

Conclusion: Prioritization of zoonotic diseases is critical as it facilitated the key One Health players in Mozambique to optimize resources, gain a greater understanding of zoonotic diseases, and implement policies and activities that promote multisectoral, interdisciplinary, and transdisciplinary collaboration across human, animal, and environmental sectors to prevent, detect, and respond to public health threats. The success of these activities implemented by the local Government and One Health partners were built from the implementation and momentum from the Mozambique's OHZDP workshop.

Rabies remains a significant public health challenge in Africa, primarily burdening impoverished rural communities, with children and young adults being the most vulnerable. Achieving complete elimination in the continent by 2030 requires a coordinated effort hinged on the One Health concept, external support from international organizations like the World Health Organization (WHO) and the national governments of endemic countries. Here, we reviewed the various socio-economic and ecological factors influencing the spatial distribution and molecular epidemiology of the disease. To mitigate the transmission of rabies on a global scale, and specifically in Africa, we proposed a multi-pronged approach including enhanced access to healthcare resources, cultural sensitization and massive health promotion with efforts geared towards promoting responsible dog and pet ownership and population management, effective monitoring, and mitigation of environmental changes.

Background: Persistent challenges of fragmented, food safety management in low- and middle-income countries underscore the need for more robustly coordinated mechanisms. National food safety technical working groups, operating under a One Health framework, offer potential in streamlining coordination efforts to effectively address these challenges. However, more clarity regarding their formation and functioning is important for understanding how to best establish and support such groups. The aim of this study is to systematically document the development process of established groups in Vietnam and Ethiopia.

Methods: We assess the process used to establish and support the technical working groups against six critical success factors for multisectoral collaboration: drive change, define, design, realise, relate, and capture success. To do so, we review meeting minutes, Terms of Reference, and other related publications.

Results: The analysis underscores the importance of financial and technical support by development partners in initiating working groups while also highlighting the challenge posed by the absence of legal frameworks to secure government commitment. Embedding the technical working groups within existing government structures - such as One Health platforms - from the outset could help to ensure the active participation and sustainability of such groups.

Conclusion: Both Vietnam and Ethiopia have established operational and institutionalized technical working groups to bolster national food safety efforts under a One Health framework. The approaches employed in these countries could serve as valuable models for others seeking to establish comparable multisectoral collaborative mechanisms to address emerging health risks.

Background: Human activities including deforestation, urbanization, and wildlife exploitation increase the risk of transmission of zoonotic diseases. Urban and peri-urban wildlife species often flourish in human-altered environments, with their survival and behavior heavily influenced by human-generated food and waste. In Catalonia, Spain, and other Mediterranean regions, species of rodents, including the house mouse (Mus musculus), black rat (Rattus rattus), Norway rat (Rattus norvegicus), as well as wild boar (Sus scrofa) are common in urban and peri-urban areas. These species host numerous infectious agents, including coronaviruses (CoVs), posing potential human health risks. During the coronavirus disease 2019 (COVID-19) pandemic, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) evolved to infect previously non-susceptible species, with variants capable of infecting rodents, emphasizing their importance in surveillance studies.

Methods: The present study assessed SARS-CoV-2 presence and/or exposure in 232 rodents, 313 wild boar, and 37 Vietnamese Pot-bellied pigs in Catalonia during the pandemic period (2020-2023).

Results: All the animals tested for acute SARS-CoV-2 infection (232 rodents and 29 wild boar) were negative. For SARS-CoV-2 exposure, 3 out of 313 (0.96%) wild boar tested positive by ELISA, while the remaining 32 rodents, 310 wild boar, and 37 Vietnamese Pot-bellied pigs were all negative. Cross-reactivity with other CoVs was predicted for ELISA-positive samples, as the 3 wild boar tested negative by the virus neutralization assay, considered as the gold standard technique.

Conclusions: The absence of SARS-CoV-2 exposure or acute infection in wild boar and rodent species supports their negligible role in viral spread or transmission during the COVID-19 pandemic in Catalonia. However, their proximity to humans and the ongoing genetic evolution of SARS-CoV-2 underline the need for continued monitoring. Surveillance of SARS-CoV-2 infection in animal species can contribute to design measures to control the emergence of new animal reservoirs or intermediate hosts that could facilitate viral spillover events.

Background: One Health (OH) is defined as a unifying approach aiming to sustainably balance and optimise the health of people, animals and the ecosystem. It recognises that the health of humans, animals (both domestic and wild), plants and the wider ecosystem are both interdependent and linked. As a concept, it aims to address complex problems requiring input from multiple disciplines. Suitable issues for OH approaches typically include global issues which can widely impact not only the health of humans and animals, but also have a significant environmental impact. Examples include emerging zoonotic diseases and antimicrobial resistance (AMR). Interpretations and use of the term OH differ in the literature and have the potential to dilute its impact. The meaning of OH among the research community has evolved over time. Here, we collate the OH relevant literature from the last two decades, identifying major themes and trends and considering how OH has been embraced differently across various geographical regions.

Methods and results: Bibliographic databases were searched using the term "One Health" AND ("Veterinary" OR "Animal") AND ("Medicine" OR "Human") AND ("Environment" OR "Ecosystem") during the period between 1980 and 2022. Data analysis and narrative synthesis identified themes, similarities, and differences within literature. Web of Science and PubMed returned 948 and 1250 results for the period mentioned above. The predominant literature focused on human health, with veterinary health second, although often to benefit human health. It was found that OH is often utilised as a public health approach, generally towards the end of disease surveillance and control. Interestingly, while authors from low- and middle-income countries were well-represented within studies using the term OH, they were less well-represented as corresponding authors.

Conclusions: The predominant focus of the literature was on human and veterinary health, implying OH approach is human-orientated, despite its suggestion that all domains share a common 'health'. Potential improvement to OH could be achieved through greater incorporation of the environmental and social sciences for a more encompassing approach.

Background: Reducing antimicrobial resistance (AMR) requires a multidisciplinary One Health approach, which necessitates buy-in from all stakeholders. In Aotearoa New Zealand, where the dairy industry is one of the largest users of antimicrobials, there are ongoing efforts to optimise antimicrobial usage (AMU) to minimise the development of AMR. These include regulations around the veterinary authorisation of the use of antibiotics by farmers without the need for a specific prescription ("the RVM process") and programmes such as the New Zealand Veterinary Association's antibiotic 'Traffic Light System'. The goal of this pilot survey was to develop and trial a questionnaire to determine how much Aotearoa dairy farmers understand about One Health, AMR, the RVM process and how their actions regarding AMU affect the wider environment.

Methods: A 55-question semi-structured questionnaire was piloted on 15 dairy farms in the Lower North Island of Aotearoa New Zealand via an in-person semi-structured interview between September and November 2021.

Results: None of the interviewed farmers could define the term One Health. However, the majority found the RVM process to be of use on their farm, although admitted they generally felt frustration regarding AMR, seeing it as a blockage to productivity, and lacked awareness regarding how their actions were related to its development. Of the farmers interviewed over half had not heard of the traffic light system, and of those who had, one admitted they refused to adhere to it.

Conclusions: This survey's novel findings have highlighted that there are notable gaps within dairy farmer understanding of AMU, AMR and One Health as well as highlighting that veterinarians could do more to keep their clients informed of their important role within One Health. There is still a lot more work to do with regards to vets, farmers and industry representatives working together to embrace One Health. Simple solutions would be to encourage farmers returning unused drugs to their veterinarians for correct disposal and to actively engage farmers further regarding AMU and AMR, so that these end-product users do not feel disconnected from the process.

One Health is being promoted as a transformative approach in health, conservation, and environmental sustainability. The polycrisis of climate change, pandemics, food insecurity, biodiversity loss, pollution and inequity is creating an urgency to evolve the epistemology and methods of One Health. However, the amount of effort placed into critical and systematic reflection on One Health is outweighed by advocacy for its use, or for expanding its scope of practice. This paper advocates for reflective One Health practice to foster new ways of knowing and doing that are helpful in the face of a rapidly narrowing window of opportunity to preserve the social and environmental factors that secure health and resilience for all species and generations. We propose six areas for reflection; (1) how to moderate conformity so that One Health does not become its own silo; (2) finding the moral purpose of One Health to align actions with desired outcomes; (3) coping with the problem of too many interacting problems; (4) the strategic trajectory of growth to accelerate action on root causes and ensure One Health is future-ready; (5) how to identify priorities across a vast array of problems, values, and needs and (6) how to know if we are making the world healthier and safer and for whom. Reflective practice requires investment in ongoing conversation to guard against over-confidence that we have captured the "one right way" to meet changing expectations and circumstances in a fair and effective way. Our intention is to stimulate thinking and discussion within the One Health community to ensure that "doing is shaped by knowing". We hope One Health will continue to be an emergent and highly variable set of ever more effective practices that constantly changes in response to the complex, interconnected and changing problems facing the health of people, animals, and the environment.
