One Health research and training and government support for One Health in South Asia

Global One Health post-graduate programmes: a review

BACKGROUND

The One Health (OH) approach recognises that humans, animals, plants, and the environment are interrelated, and therefore seeks to facilitate collaboration, communication, coordination, and capacity building between relevant stakeholders to achieve a healthier ecosystem. This calls for integrating OH into established governance, policy, health, education, and community structures, and requires OH professionals equipped with the necessary inter and trans-disciplinary skillset. Therefore, numerous OH training programmes are currently being offered globally. However, the coordination and contents of some of these trainings have been criticised as inconsistent and inadequately standardised, and therefore could serve as a barrier to OH implementation. In this study, an up-to-date repository of a subset of OH academic programmes offered globally was provided, and their curricula contents was critically assessed.

METHODS

Between December 2022 and April 2023, an online search for key terms 'ONE HEALTH MASTERS COURSES', and 'ONE HEALTH MASTERS PROGRAMMES' together with variations of 'AFRICA', 'NORTH AMERICA', 'ASIA', 'AUSTRALIA', 'EUROPE', 'GLOBAL' was conducted. Details about course title, delivery mode, joint administration status, curricula contents, language of instruction, years to completion, host university, country, and continent were collected.

RESULTS

Forty-three programmes met inclusion criteria of the study, and almost all (n = 36, 83.7%) were tailored towards infectious diseases and population/global health, compared to the environmental and conservation perspectives. Compiled curricula contents clustered into one of these 12 sub-headings: 'principles and concepts of OH', 'epidemiology and biostatistics', 'major branches of OH', 'internship/externship/research project', 'infectious diseases, zoonoses, and surveillance', 'risk analysis and crises management', 'food safety, microbiology, immunology, and allied', 'communication', 'ethics', 'economics, policy, and management' and 'others. Of these, infectious disease themes were the most common. Regarding geography and organising institutions, North America and Europe, and veterinary institutions, respectively, were the most represented.

CONCLUSION

Despite the multi-level diversity observed, uniformity still exists across the programmes which favours interdisciplinary cross-talks. Future pedagogical studies that objectively assess the alignment of module contents with the OH core competencies and the impacts of these OH programmes is recommended. With this study, a critical information gap that has existed for long in the OH field has been bridged.

The Past, Present, and Future of One Health in India: A Narrative Review

Humans have experienced a long-lasting pandemic of COVID-19 going on since the year 2020. Such events have recently increased the demand for a competent disease outbreak response system, more precisely, a One Health platform. The interaction between humans, animals, and ecosystems is inevitable. It is a known fact that the interface between these three entities is important for survival. In rural areas, especially in developing countries, it is a common practice to keep the animal shed in close proximity to their homes. Further, this intricate relationship itself plays a role in the spread and transmission of the disease. The involvement of the human-animal interface in emerging and re-emerging diseases has caused havoc in recent times and might prove challenging to overcome. Over the years, many efforts have been made on international and national platforms to adopt and implement a transdisciplinary, collaborative, intersectoral approach in India. This review highlights the major initiatives taken for the implementation of one health and the challenges faced over the years in our country.

A generalizable one health framework for the control of zoonotic diseases

Effectively preventing and controlling zoonotic diseases requires a One Health approach that involves collaboration across sectors responsible for human health, animal health (both domestic and wildlife), and the environment, as well as other partners. Here we describe the Generalizable One Health Framework (GOHF), a five-step framework that provides structure for using a One Health approach in zoonotic disease programs being implemented at the local, sub-national, national, regional, or international level. Part of the framework is a toolkit that compiles existing resources and presents them following a stepwise schematic, allowing users to identify relevant resources as they are required. Coupled with recommendations for implementing a One Health approach for zoonotic disease prevention and control in technical domains including laboratory, surveillance, preparedness and response, this framework can mobilize One Health and thereby enhance and guide capacity building to combat zoonotic disease threats at the human-animal-environment interface.

Antimicrobial Resistance in Rural Settings in Latin America: A Scoping Review with a One Health Lens

Antimicrobial resistance (AMR) in rural Latin America is not fully understood. The transmission pathways are partially known since research predominantly focuses on the urban hospital setting. The contribution to AMR from environmental factors is usually only mentioned in large-scale animal production. To understand the state of the literature on AMR in rural LA, we carried out a scoping review using the One Health (OH) perspective. OH recognises the concomitant contributions and interconnectedness of humans, animal, and the environment, thus, we used the OH perspective to select those articles adopting a holistic view of the problem. We searched original articles in English, Spanish, and Portuguese in four peer-reviewed databases and included 21 publications in the analysis. We charted data on bibliometrics, design, data collection sources, and instruments. We identified the human, animal, and environmental contributions to AMR in rural locations, and information gaps on AMR transmission routes and AMR drivers. Intensive and non-intensive animal production systems and agricultural practices were the most frequently found human contributions to AMR. Poultry, swine, cattle, and fish were the most frequent livestock mentioned as sources of AMR bacteria. Animal carriage and/or transfer of AMR determinants or bacteria was recognised as the primary contribution of livestock to the problem, while water, soil, and farming were predominant environmental contributions. We found that only 1 article out of 21 considered the OH approach as a framework for their sampling scheme, whereas 5 out 21 discussed all the three OH components. There were hardly any descriptions of humans or human waste as reservoirs for AMR in rural locations, and rural health centres or hospitals and wildlife were not represented. No studies identified mining as an anthropogenic activity driving AMR. More OH-oriented studies, with emphasis on molecular approaches—for identification and comparison of AMR genes—are sorely needed to understand better the existence of a network of interconnected transmission routes in rural Latin America and provide efficient strategies to prevent further AMR emergence.

Operationalising the "One Health" approach in India: facilitators of and barriers to effective cross-sector convergence for zoonoses prevention and control

BACKGROUND

There is a strong policy impetus for the One Health cross-sectoral approach to address the complex challenge of zoonotic diseases, particularly in low/lower middle income countries (LMICs). Yet the implementation of this approach in LMIC contexts such as India has proven challenging, due partly to the relatively limited practical guidance and understanding on how to foster and sustain cross-sector collaborations. This study addresses this gap by exploring the facilitators of and barriers to successful convergence between the human, animal and environmental health sectors in India.

METHODS

A mixed methods study was conducted using a detailed content review of national policy documents and in-depth semi-structured interview data on zoonotic disease management in India. In total, 29 policy documents were reviewed and 15 key informant interviews were undertaken with national and state level policymakers, disease managers and experts operating within the human-animal-environment interface of zoonotic disease control.

RESULTS

Our findings suggest that there is limited policy visibility of zoonotic diseases, although global zoonoses, especially those identified to be of pandemic potential by international organisations (e.g. CDC, WHO and OIE) rather than local, high burden endemic diseases, have high recognition in the existing policy agenda setting. Despite the widespread acknowledgement of the importance of cross-sectoral collaboration, a myriad of factors operated to either constrain or facilitate the success of cross-sectoral convergence at different stages (i.e. information-sharing, undertaking common activities and merging resources and infrastructure) of cross-sectoral action. Importantly, participants identified the lack of supportive policies, conflicting departmental priorities and limited institutional capacities as major barriers that hamper effective cross-sectoral collaboration on zoonotic disease control. Building on existing informal inter-personal relationships and collaboration platforms were suggested by participants as the way forward.

CONCLUSION

Our findings point to the importance of strengthening existing national policy frameworks as a first step for leveraging cross-sectoral capacity for improved disease surveillance and interventions. This requires the contextual adaptation of the One Health approach in a manner that is sensitive to the underlying socio-political, institutional and cultural context that determines and shapes outcomes of cross-sector collaborative arrangements.

Rabies control in South Asia requires a One Health approach

Rabies is a vaccine-preventable viral disease present in more than 150 countries around the world. Globally, almost 60,000 people die each year from rabies, of which more than 58% are in Asia and around 45% in South Asia with especially high incidence in India, Pakistan and Bangladesh. Vaccination coverage of both people and stray dogs is low in the region and in general people are not given enough protection and information about pre- and post-exposure prophylaxis. Engagement of multiple sectors and One Health collaboration including community education, awareness programmes and vaccination campaigns are critical to control and elimination of rabies.

Leptospira interrogans Serovar Hardjo Seroprevalence and Farming Practices on Small-Scale Dairy Farms in North Eastern India; Insights Gained from a Cross-Sectional Study

Leptospirosis is a zoonotic disease of major public health concern in India. Bovines play an important role in maintaining and transmitting this disease and proximity between dairy cows and humans makes the dairy cow-human nexus a transmission route of public health interest, yet one currently under-examined in North Eastern India. We report a cross-sectional survey carried out on small-scale dairy farms in the states of Assam and Bihar in North Eastern India investigating seroprevalence for Leptospira interrogans serovar Hardjo, the most common pathogenic serovar reported in cattle worldwide. Higher seroprevalence was reported on dairy farms in Bihar 4.5% (95% CI 2.6–7.5%) than in Assam 1.2% (95% CI 0.42–3.6%), but overall seroprevalence levels were low. The study is the first indication of leptospirosis circulating in small-scale dairy farms in these states. To correlate farming practices with zoonotic risk, we combined results from a dairy farmer questionnaire with cow seroprevalence. However, low seroprevalence levels found in this study made the identification of risk factors difficult. Nevertheless, poor farming practices around hygiene and biosecurity on dairy farms have been highlighted. Implementing simple measures could mitigate environmental contamination, and therefore, reduce the risk of Leptospira interrogans, and other zoonoses transmission, at the animal-environment-human interface.

Systemic factors for enhancing intersectoral collaboration for the operationalization of One Health: a case study in India

Background

One Health is a collaborative, multisectoral, and transdisciplinary approach—working at the local, regional, national, and global levels—with the goal of achieving optimal health outcomes recognizing the interconnection between people, animals, plants, and their shared environment. Operationalization of the One Health approach is still unclear for various local health systems with their respective targets. In this scenario, the empirical study of intersectoral collaboration between the human and animal health systems provides an opportunity to investigate the appropriate strategies and their enabling factors at the local health system level. Thus, this study documented and validated the innovative strategy for intersectoral collaboration, focusing on effectual prevention and control of zoonotic diseases with its enabling factors for a city in western India, Ahmedabad.

Methods

This case study was conducted in three phases: phase I (qualitative data collection, i.e., vignette interview), phase II (quantitative data collection through modified policy Delphi), and phase III (participatory workshop). The vignette data were handled for content analysis, and the Delphi data, like other quantitative data, for descriptive statistics. The participatory workshop adapts the computerized Sensitivity Model^® developed by Vester to analyse the health system dynamics.

Result

Out of the possible 36 strategies, this study validated the top 15 essential (must-have) and five preferred (should-have) strategies for the study area. For operationalization of the One Health approach, the enabling factors that were identified through the systems approach are micro-level factors at the individual level (trust, leadership, motivation, knowledge), meso-level factors at the organizational level (human resource, capacity-building, shared vision, decision-making capacity, laboratory capacity, surveillance), macro-level factors at the system level (coordinated roles, relationships, common platform), and external factors outside of the system (guidelines/policies, community participation, a specific budget, political will, smart technology).

Discussion

This study reveals that the micro-level factors at the individual level are potential levers of the health system. More attention to these factors could be beneficial for the operationalization of the One Health approach. This study recommends a systems approach through a bottom-up exploration to understand the local health system and its enabling factors, which should be accounted for in formulating future One Health policies.

One Health information management: health system reforms to support social well-being in Thailand

Background and Aim: The information about the health problems interaction between animal health, ecosystems, and human health that the "One Health (OH)" concept is becoming more complex. This study focused on OH information in Thailand to develop guidelines for establishing a "One Health Information Management (OHIM)" system by drafting the structure of an OH information strategic plan. Materials and Methods: A mixed methods approach was used and included questionnaires, interviews, focus groups, and observations in agencies across the country to gather evidence about actions relating to the OH concept, such as the Memorandum of Agreements between the Ministry of Public Health and eight main agencies. Results: The study concentrated on the key issue that understanding the OH concept is difficult, as the environment and human health sectors include less knowledge of this concept than the animal health sector. Further, there are concerns about the comprehension of OH concepts, and high-level information management and data storage relating to OH, including medicine, cattle, wild animal, environment, and environmental resource management. Data from OH researchers and publicly accessible government data are less integrated and inconsistently managed across agencies. Conclusion: The study of OHIM strategic development should consist of four important points: (1) Clarity in the OH concept, (2) OH staff development, (3) development of an OHIM data network and innovation, and (4) research and academic development, and global OHIM academic exchange. All of these points will lead to health system reforms to support social well-being.

One Health, "Disease X" & the challenge of "Unknown" Unknowns

The emergence of SARS-CoV-2 and its rapid spread globally emphasizes the ever-present threat of emerging and re-emerging infectious diseases. In this review, the pathogen pyramid framework was utilized to identify the "unknown unknowns" associated with the emergence and rapid transmission of novel infectious disease agents. Given that the evolutionary origin of most of the emerging infectious disease agents can be traced to an animal source, we argue the need to integrate the "One Health" approach as a part of surveillance activities. The need for focusing on undertaking global and regional mapping activities to identify novel pathogens is discussed, given that there are an estimated 1.67 million unknown viruses, of which around 631,000 to 827,000 unknown viruses have the capacity to infect human beings. The emerging risks due to the ever-expanding interface between human, animals, both domestic and wildlife, and the environment are highlighted, these are largely driven by the need for safe habitation, growing food, developing infrastructure to support the increasing human population and desire for economic growth. The One Health approach provides a holistic way to address these cross-sectoral issues, by bridging institutional gaps, enumerating priority risk areas and pathogens, and highlighting putative risk factors for subsequent spillover events involving emerging and re-emerging infectious disease pathogens at the human-animal-environment interface.

Adopting an intersectoral One Health approach in India: Time for One Health Committees

Following the several episodes of zoonotic disease outbreaks and the more recent COVID-19 pandemic, the Indian policy initiatives are committed to institutionalize One Health (OH) approaches and promote intersectoral, transdisciplinary collaboration and cooperation. The OH principle needs to be visualized beyond the scope of zoonoses. While conservation, ecological and veterinary professions are getting increasingly engaged with OH, most of the medical/clinical and social sciences professions are only peripherally aware of its nuances. The OH initiatives, by their essentially multidisciplinary nature, entail working across ministries and navigating tacit institutional hierarchies and allocating leadership roles. The logical operational step will be the constitution of One Health Committees (OHC) at the State and district levels. Here, we outline the key foundational principles of OHC and hope that the framework for implementation shall be deliberated through wider consultations and piloted and adopted in a phased manner.

Mitigating Future Respiratory Virus Pandemics: New Threats and Approaches to Consider

Despite many recent efforts to predict and control emerging infectious disease threats to humans, we failed to anticipate the zoonotic viruses which led to pandemics in 2009 and 2020. The morbidity, mortality, and economic costs of these pandemics have been staggering. We desperately need a more targeted, cost-efficient, and sustainable strategy to detect and mitigate future zoonotic respiratory virus threats. Evidence suggests that the transition from an animal virus to a human pathogen is incremental and requires a considerable number of spillover events and considerable time before a pandemic variant emerges. This evolutionary view argues for the refocusing of public health resources on novel respiratory virus surveillance at human-animal interfaces in geographical hotspots for emerging infectious diseases. Where human-animal interface surveillance is not possible, a secondary high-yield, cost-efficient strategy is to conduct novel respiratory virus surveillance among pneumonia patients in these same hotspots. When novel pathogens are discovered, they must be quickly assessed for their human risk and, if indicated, mitigation strategies initiated. In this review, we discuss the most common respiratory virus threats, current efforts at early emerging pathogen detection, and propose and defend new molecular pathogen discovery strategies with the goal of preempting future pandemics.

Biodiversity and Human Health Interlinkages in Higher Education Offerings: A First Global Overview

Introduction: Biodiversity is inextricably linked to human health. As an important area of research of the Convention on Biological Diversity and a key avenue for the dissemination of biodiversity and health knowledge, we investigated how well-embedded biodiversity and health interlinkages are in institutional higher education offerings.

Methods: Using One Health education programs as a starting point, we collected a global list of institutions potentially carrying out education in the links between biodiversity and health through previously published research, academic partners of global conglomerates, and our own networks. We then analyzed the offerings from these institutions to determine the degree of integration of biodiversity and health interlinkages.

Results: We found 105 educational offerings in biodiversity and health interlinkages from 89 institutions in 30 countries. These were primarily found in faculties of public health, veterinary sciences, and medicine, with varying degrees of coverage of the interlinkages.

Conclusion: Education incorporating the links between biodiversity and health exists globally, but should be more widely integrated, particularly through inter-faculty and inter-institutional collaboration.

'One Health' Actors in Multifaceted Health Systems: An Operational Case for India

The surging trend of (re)emerging diseases urges for the early detection, prevention, and control of zoonotic infections through the One Health (OH) approach. The operationalization of the OH approach depends on the contextual setting, the presence of the actors across the domains of OH, and the extent of their involvement. In the absence of national operational guidelines for OH in India, this study aims to identify potential actors with an attempt to understand the current health system network strength (during an outbreak and non-outbreak situations) at the local health system of Ahmedabad, India. This case study adopted a sequential mixed methods design conducted in two phases. First, potential actors who have been involved directly or indirectly in zoonoses prevention and control were identified through in-depth interviews. A network study was conducted as part of the second phase through a structured network questionnaire. Interest and influence matrix, average degree, network density, and degree of centralization were calculated through Atlas.Ti (ATLAS.ti Scientific Software Development GmbH, Berlin, Germany), UCINET (Analytic Technologies, Lexington, KY, USA) software. The identified actors were categorized based on power, administrative level (either at the city or district level), and their level of action: administrative (policy planners, managers), providers (physicians, veterinarians), and community (health workers, community leaders). The matrix indicated that administrative actors from the district level were ‘context setters’ and the actors from the city level were either ‘players’ or ‘subjects’. The network density showed a strength of 0.328 during the last outbreak of H5N1, which decreased to 0.163 during the non-outbreak situation. Overall, there was low collaboration observed in this study, which ranged from communication (during non-outbreaks) to coordination (during outbreaks). The private and non-governmental actors were not integrated into collaborative activities. This study concludes that not only collaboration is needed for OH among the sectors pertaining to the human and the animal health system but also better structured (‘inter-level’) collaboration across the governance levels for effective implementation.

Review of rabies in Nepal

Rabies is a global problem, but the burden is higher in less developed or developing countries of Asia and Africa. In Nepal, rabies is reported to kill around 500 animals and up to 32 human beings in recent years, with possible under-reporting of cases and deaths. As a prophylactic measure, around 30,000 livestock and 300,000 humans get vaccinated each year in Nepal. This review summarizes the past, present and future perspectives of rabies control and prevention in Nepal. The global strategic plan of World Health Organization (WHO) aims to bring human deaths from dog-transmitted rabies to zero by 2030. To achieve this goal of ‘Zero by 30’, the concerned governmental and non-governmental agencies in Nepal should work together using the One Health concept.

•

Rabies is caused by Lyssa virus that is responsible for deaths of 55,000 people annually across the world.

•

Dogs are responsible for 95% of rabies cases around the globe and 99% in endemic regions.

•

Asia has the highest burden of rabies and India alone accounts for around 35% of world rabies cases.

•

In Nepal, less than 35 people have died each year due to rabies.

•

One health approach is mandatory to end dog mediated rabies by the year 2030.

Molecular characterization of B. anthracis isolates from the anthrax outbreak among cattle in Karnataka, India

Background

Anthrax, a zoonotic disease is caused by the Gram positive bacterium Bacillus anthracis. During January 2013, an anthrax outbreak among cattle was reported in Gundlupet Taluk, neighboring Bandipur National Park and tiger reserve, India. The present study aims at the molecular identification and characterization of 12 B. anthracis isolates from this outbreak by 16S rRNA gene sequencing, screening B. anthracis specific prophages and chromosomal markers, protective antigen (pag) gene and canonical single nucleotide polymorphism (canSNP) analysis to subtype the isolates into one of the twelve globally identified clonal sub-lineages of B. anthracis.

Results

These isolates had identical 16S rDNA nucleotide sequences with B. anthracis specific dual peaks showing mixed base pair R (G/A) at position 1139 with visual inspection while the automated basecaller software indicated a G. Alternatively the nucleotide A at 1146 position was indicative of the 16S rDNA type 7. Multiple sequence alignment with additional 170 (16S rDNA) sequences of B. cereus sensu lato group from GenBank database revealed 28 new 16S types in addition to eleven 16S types reported earlier. The twelve B. anthracis isolates were found to harbor the four B. anthracis specific prophages (lambdaBa01, lambdaBa02, lambdaBa03, and lambdaBa04) along with its four specific loci markers (dhp 61.183, dhp 77.002, dhp 73.019, and dhp 73.017). The pag gene sequencing identified the isolates as protective antigen (PA) genotype I with phenylalanine-proline-alanine phenotype (FPA phenotype). However, sequence clustering with additional 34 pag sequences from GenBank revealed two additional missense mutations at nucleotide positions 196 bp and 869 bp of the 2294 bp pag sequence among the 5 B. cereus strains with pXO1 like plasmids. The canSNP analysis showed that the isolates belong to A.Br.Aust94 sub-lineage that is distributed geographically in countries of Asia, Africa, Europe and Australia.

Conclusions

The analysis of 16S rDNA sequences reiterated the earlier findings that visual inspection of electropherogram for position 1139 having nucleotide R could be used for B. anthracis identification and not the consensus sequence from base caller. The canSNP results indicated that the anthrax outbreak among cattle was caused by B. anthracis of A.Br.Aust94 sub-lineage.

The 2019 novel coronavirus disease (COVID-19) pandemic: A review of the current evidence

A novel coronavirus (nCoV) spillover event, with its epicenter in Wuhan, People's Republic of China, has emerged as a public health emergency of international concern. This began as an outbreak in December 2019, and till February 28, 2020, there have been 83,704 confirmed cases of novel coronavirus disease 2019 (COVID-19) globally, with 2,859 deaths, resulting in an overall case fatality rate of 3.41 per cent (95% confidence interval 3.29-3.54%). By this time (February 28, 2020) 58 countries or territories and one international conveyance (Diamond Princess Cruise Ship) were affected. As a part of the global response to manage and contain the pandemic, major emphasis was placed on generating research intelligence to guide evidence-based responses to contain the virus, which was named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), owing to its genetic similarities with the SARS virus. This review summarizes the emerging evidence which can help guide the public health response, particularly in India. Key areas have been identified in which research needs to be conducted to generate critical intelligence for advising prevention and control efforts. The emergence of SARS-CoV-2 has once again exposed the weaknesses of global health systems preparedness, ability to respond to an infectious threat, the rapidity of transmission of infections across international borders and the ineffectiveness of knee-jerk policy responses to emerging/re-emerging infectious disease threats. The review concludes with the key learning points from the ongoing efforts to prevent and contain COVID-19 and identifies the need to invest in health systems, community-led response mechanisms and the need for preparedness and global health security.

An exploratory study of factors associated with human brucellosis in mainland China based on time-series-cross-section data from 2005 to 2016

Objective

Many studies focused on reasons behind the increasing incidence and the spread of human brucellosis in mainland China, yet most of them lacked comprehensive consideration with quantitative evidence. Hence, this study aimed to further investigate the epidemic mechanism and associated factors of human brucellosis so as to provide thoughts for future countermeasures in China and the rest of the world.

Methods

Data of human brucellosis incidence and some associated factors in economy, animal husbandry, transportation as well as health and hygiene were collected at provincial level from 2005–2016. Time series plots were first used to visualize the annual incidence and annual rate of change of human brucellosis for each province, then cluster analysis categorized all the 31 provinces of mainland China based on their incidence time series during the study period. In addition, according to the characteristics of data, the dynamic panel data model in combination with supervised principal component analysis was proposed to explore effects of associated factors on human brucellosis.

Results

1. The incidence rate of human brucellosis in mainland China increased three-fold from 1.41 per 100,000 people in 2005 to 4.22 per 100,000 people in 2014, though it went down a little in 2015 and 2016. Incidence rates in the north have always been higher than those in the south, but the latter also experienced an upward trend especially between 2012 and 2016. 2. The 31 provinces of mainland China were categorized into three clusters, and each cluster had its own characteristics of incidence time series. 3. The impact of health and hygiene situations on the prevention and control work of human brucellosis was still very limited and trivial (regression coefficient = -0.02). Therefore, it was plausible to presume that improving the personal average number of medical institutes and the proportion of rural medical expenditure might be helpful in preventing and controlling human brucellosis.

Conclusions

The epidemic status of human brucellosis has changed in both spatial and temporal dimensions in recent years in mainland China. Apart from traditional control measures, more attention should be paid to the improvement of medical healthcare especially in rural areas in the hope of enhancing the control effect.

The growth and strategic functioning of One Health networks: a systematic analysis

BACKGROUND

The recent increase in attention to linkages between human health, animal health, and the state of the environment has resulted in the rapid growth of networks that facilitate collaboration between these sectors. This study ascertained whether duplication of efforts is occurring across networks, which stakeholders are being engaged, and how frequently monitoring and evaluation of investments is being reported.

METHODS

This study is a systematic analysis of One Health networks (OHNs) in Africa, Asia, and Europe. We defined an OHN as an engagement between two or more discrete organisations with at least two of the following sectors represented: animal health, human health, and the environment or ecosystem. Between June 5 and Sept 29, 2017, we systematically searched for OHNs in PubMed, Google, Google Scholar, and relevant conference websites. No language restrictions were applied, but we were only able to translate from English and French. Data about OHNs, including their year of initiation, sectors of engagement, regions of operation, activities conducted, and stakeholders involved, were extracted with a standardised template and analysed descriptively.

FINDINGS

After screening 2430 search results, we identified and analysed 100 unique OHNs, of which 86 were formed after 2005. 32 OHNs covered only human and animal health, without engaging with the role of the environment on health. 78 OHNs involved academic bodies and 78 involved government bodies, with for-profit organisations involved in only 23 and community groups involved in only ten. There were few collaborations exclusively between networks in the developing world (four OHNs) and only 15 OHNs reported monitoring and evaluation information. The majority of OHNs worked on supporting communication, collaboration, information sharing, and capacity building.

INTERPRETATION

Amid concerns about there being insufficient strategic direction and coordination in the growth of OHNs, our study provides empirical evidence about limitations in stakeholder representation, apparently absent or ambiguous monitoring and evaluation structures, and potential areas of duplication. The collective strategic functioning of OHNs might be improved by more transparent reporting of goals and outcomes of OHN activities, as well as more collaborations led by networks within the developing world and increased attention to environmental health.

FUNDING

None.

Checklist for One Health Epidemiological Reporting of Evidence (COHERE)

One Health is defined as the intersection and integration of knowledge regarding humans, animals, and the environment, yet as the One Health scientific literature expands, there is considerable heterogeneity of approach and quality of reporting in One Health studies. In addition, many researchers who publish such studies do not include or integrate data from all three domains of human, animal, and environmental health. This points to a critical need to unify guidelines for One Health studies. This report details the Checklist for One Health Epidemiological Reporting of Evidence (COHERE) to guide the design and publication format of future One Health studies. COHERE was developed by a core writing team and international expert review group that represents multiple disciplines, including human medicine, veterinary medicine, public health, allied professionals, clinical laboratory science, epidemiology, the social sciences, ecohealth and environmental health. The twin aims of the COHERE standards are to 1) improve the quality of reporting of observational or interventional epidemiological studies that collect and integrate data from humans, animals and/or vectors, and their environments; and 2) promote the concept that One Health studies should integrate knowledge from these three domains. The 19 standards in the COHERE checklist address descriptions of human populations, animal populations, environmental assessment, spatial and temporal relationships of data from the three domains, integration of analyses and interpretation, and inclusion of expertise in the research team from disciplines related to human health, animal health, and environmental health.

One Health/EcoHealth capacity building programs in South and South East Asia: a mixed method rapid systematic review

BACKGROUND

Although One Health (OH) or EcoHealth (EH) have been acknowledged to provide comprehensive and holistic approaches to study complex problems, like zoonoses and emerging infectious diseases, there remains multiple challenges in implementing them in a problem-solving paradigm. One of the most commonly encountered barriers, especially in low- and middle-income countries, is limited capacity to undertake OH/EH inquiries. A rapid review was undertaken to conduct a situation analysis of the existing OH/EH capacity building programs, with a focused analysis of those programs with extensive OH engagement, to help map the current efforts in this area.

METHODS

A listing of the OH/EH projects/initiatives implemented in South Asia (SA) and South East Asia (SEA) was done, followed by analysis of documents related to the projects, available from peer-reviewed or grey literature sources. Quantitative data was extracted using a data extraction format, and a free listing of qualitative themes was undertaken.

RESULTS

In SEA, 13 unique OH/EH projects, with 37 capacity building programs, were identified. In contrast, in SA, the numbers were 8 and 11 respectively. In SA, programs were oriented to develop careers in program management, whereas, in SEA, the emphasis was on research. Two thirds of the programs in SEA had extensive OH engagement, whereas only one third of those in SA did. The target for the SEA programs was wider, including a population more representative of OH stakes. SEA program themes reveal utilization of multiple approaches, usually in shorter terms, and are growing towards integration with the traditional curricula. Such convergence of themes was lacking in SA programs. In both regions, the programs were driven by external donor agencies, with minimal local buy-in.

CONCLUSIONS

There is limited investment in research capacity building in both SA and SEA. The situation appears to be more stark in SA, whilst SEA has been able to use the systematic investment and support to develop the OH/EH agenda and strategize capacity building in the core competencies. In order to effectively address the disease emergence hotspots in these regions, there needs to be strategic funding decisions targeting capacity building in the core OH/EH competencies especially related to transdisciplinarity, systems thinking, and adaptive management.

One Health research and training in Australia and New Zealand

Purpose of the review

This review was performed to create a repository of information on One Health research and training in Australia and New Zealand (ANZ). The review sought to determine 1) how many training activities there are in ANZ, 2) how much research on zoonotic diseases is undertaken by multidisciplinary teams, and 3) how collaborative and integrated they are.

Recent findings

There are few opportunities for training in One Health in ANZ. The majority require enrolment in a postgraduate degree programme, and there is only one postgraduate level course that is also available for continuing professional development (CPD). Of the broad range of One Health research performed in ANZ, the majority is performed by teams with limited disciplinary diversity, although diversity is improving.

Summary

Progress has been made in building collaboration between human, animal, and environmental health professions. However, the lack of clearly defined competencies and agreed purpose for One Health may be impeding collaboration.
