International Open Access Week is an annual scholarly communication event that is marked globally during the last full week of October to raise awareness about open access publishing of research and scholarly outputs to enable their universal online accessibility. The theme of Open Access Week 2021 (25 to 31 Oct) is ‘It matters how we open knowledge: Building structural equity’.

In the field of academic and research publishing, the peer-reviewed journal article is considered as the ‘gold standard’ for quality research outputs. However, many researchers nowadays also consider preprints as important and highly relevant outputs that contribute to the body of knowledge and enable discoverability of current research developments.

A preprint is a version of a scholarly or research manuscript that precedes formal peer review, typesetting and publication in a scholarly or scientific journal. Preprints are often uploaded to online preprint servers or institutional repositories where they are freely accessible as non-typeset versions of the manuscripts.

Publishing of preprints allows researchers to quickly share new findings with their peers and receive early feedback and comments which can help in revising manuscripts for submission to a scholarly journal.

At the International Livestock Research Institute (ILRI), scientists from the Animal and Human Health program carry out collaborative research to effectively manage or eliminate livestock, zoonotic and foodborne diseases that matter to the poor through the generation and use of knowledge, technologies and products, leading to higher farmer incomes and better health and nutrition for consumers and livestock.

While most of their research outputs are published as peer-reviewed journal articles, the program scientists also publish their findings in other formats including books, book chapters, conference proceedings, infographics, presentations, posters, reports, theses and videos. These outputs are all indexed in CGSpace, an open access institutional repository of agricultural research outputs.

The scientists are also increasingly making use of preprints to share their research via open access. In line with the theme of Open Access Week, we present below a curated list of preprints by scientists from ILRI’s Animal and Human Health program and research partners, to highlight the contribution of these outputs to open knowledge and open science.

The health impacts of climate change are getting worse, exposing communities around the world to greater risks of food and water insecurity, heatwaves and the spread of infectious diseases, according to a new report by the Lancet Countdown.

The Lancet Countdown is an international, multidisciplinary collaboration of leading researchers from 43 academic institutions and United Nations agencies that independently monitors the health consequences of a changing climate and publishes its findings in an annual report.

The 2021 report of the Lancet Countdown on health and climate change: code red for a healthy future was launched at a virtual event held on 21 October 2021. The report tracks 44 indicators of health impacts that are directly linked to climate change, across five key thematic groups:

  • climate change impacts, exposures and vulnerability;
  • adaptation planning and resilience for health;
  • mitigation actions and health co-benefits;
  • economics and finance; and
  • public and political engagement.

The report notes that key trends are getting worse across every indicator, affecting people in all corners of the world.

For example, the potential for outbreaks of dengue, chikungunya and Zika is increasing most rapidly in countries with a very high human development index, including European countries.

Suitability for malaria infections is increasing in cooler highland areas of countries with a low human development index.

Coasts around northern Europe and the United States of America are becoming more conducive to bacteria which produce gastroenteritis, severe wound infections and sepsis. In resource-limited countries, the same dynamic is putting decades of progress towards controlling or eliminating these diseases at risk.

The report also notes that there are 569.6 million people living less than five metres above current sea levels, who could face rising risks of increased flooding, more intense storms, and soil and water salinification. Many of these people could be forced to permanently leave these areas and migrate further inland.

In light of these and other growing climate-related risks, the authors of the report call for urgent, globally coordinated action to mitigate climate change and build a healthier, sustainable future for all.

Among the report’s co-authors is Delia Grace, professor of food safety systems at the Natural Resources Institute, University of Greenwich on joint appointment at the International Livestock Research Institute.

The world’s largest publicly-funded agricultural research partnership, CGIAR, is currently developing a series of initiatives to implement its 2030 research and innovation strategy that was launched in early 2021.

The research initiatives are designed to create lasting impact in five key areas:

  • nutrition, health and food security;
  • poverty reduction, livelihoods and jobs;
  • gender equality, youth and social inclusion;
  • climate adaptation and mitigation; and
  • environmental health and biodiversity.

One of these research initiatives, Protecting human health through a One Health approach, aims to improve the prevention and control of antimicrobial resistance, foodborne diseases and zoonoses in seven target countries: Bangladesh, Côte d’Ivoire, Ethiopia, India, Kenya, Uganda and Vietnam.

The development of the One Health initiative is being led by a team of scientists from four CGIAR research centres — the International Food Policy Research Institute (IFPRI), the International Livestock Research Institute (ILRI), the International Water Management Institute (IWMI) and WorldFish — in collaboration with external research partners from Centre Suisse de Recherches Scientifiques en Côte d’Ivoire, EcoHealth Alliance and the University of Liverpool.

To ensure alignment of the proposed initiative with national priorities, the team convened a series of online consultative meetings with research collaborators to gain insights on the main One Health priorities, challenges, interventions and partner organizations in the respective countries.

The Côte d’Ivoire meeting, hosted by ILRI, took place on Thursday 12 August 2021, bringing together some 35 participants from government ministries, universities as well as national and international research organizations.

Dieter Schillinger, ILRI’s deputy director general for biosciences research and development, opened the meeting with a word of welcome and an overview of CGIAR’s 2030 research and innovation strategy that will guide the implementation of the 33 new research initiatives, including that on One Health—the focus of the online consultation.

He mentioned that the development of the One Health research initiative is a collaborative process and ILRI is working closely with other CGIAR research centres as well as external partners from research and academia, including those represented at the meeting. He therefore welcomed feedback and suggestions from the participants to ensure the research of the One Health initiative is relevant and impactful.

Hung Nguyen, co-leader of ILRI’s Animal and Human Health program, followed with an overview of the rationale of the One Health initiative, citing the need for a One Health approach to tackle the complexity of the global public health challenges posed by the rising incidence of antimicrobial resistance, foodborne diseases and zoonoses.

He then outlined the three main objectives of the One Health initiative, namely, to generate evidence for decision-making; evaluate impacts of One Health approaches; and scale up innovations into national policies and programs.

He further highlighted the initiative’s Theory of Change, explaining how the research outputs are expected to lead to specific development outcomes and impact by 2030, in line with the United Nations Sustainable Development Goals. The team estimates that between 4 million and 41 million cases of disease will be averted annually through the initiative’s efforts.

The initiative’s research activities will take place through five work packages:

  • zoonoses;
  • food safety;
  • antimicrobial resistance;
  • environment (water and wildlife interfaces); and
  • economics, governance and behaviour.

The zoonoses work package aims to pre-empt the spread of zoonoses at the wildlife–livestock interface and reduce the incidence of zoonotic pathogens associated with poverty. Innovations include risk mapping of key endemic zoonoses and developing diagnostic kits for surveillance of zoonoses.

The food safety work package aims to reduce the burden of foodborne disease in traditional (informal) food value chains, with a focus on animal-source foods and other perishables such as fruits and vegetables. Innovations include training and certification of food handlers and traders, promotion of consumer demand for safe food, and behavioural nudges to encourage safe food handling practices.

The antimicrobial resistance work package will focus on reducing the burden of antimicrobial resistance by promoting the prudent use of antimicrobials in crop, fish and livestock production systems. Innovations include surveillance of antimicrobial resistance and communication of evidence on the costs and benefits of rational use of antimicrobials

The environment work package will focus on improving land use and water management to reduce health risks such as antimicrobial residues and zoonotic pathogens. Approaches will include recovery and reuse of animal waste to prevent water pollution and promotion of good practices to ensure the safe use of marginal quality water.

The economics, governance and behaviour work package aims to understand the drivers of people’s behaviour within food systems and the impact of policies and governance approaches on this behaviour. An example of an innovation under this work package is a performance management system for government officials responsible for implementing surveillance and enforcing regulations on antimicrobial use or food safety. Another innovation is a system to ensure inclusion of small-scale farmers, traders, food vendors and vulnerable groups so that they benefit from One Health outcomes.

During parallel group discussions on the work packages, the participants gave feedback on the main One Health challenges, priority interventions, actions to ensure inclusion and partner institutions in Côte d’Ivoire.

Among the main food safety challenges identified were the informal food sector (street foods) and low awareness on food safety. Priority interventions include risk analysis, consumer education and strengthening of capacity to assess risks.

With regard to control of zoonoses, some of the key challenges identified were non-compliance with disease control measures and non-adaptation of laws to current challenges. Priority interventions include improved communication among actors involved in control of zoonoses and an effective monitoring network.

Regarding antimicrobial resistance, some of the key challenges identified were environmental contamination through hospital and slaughterhouse waste, misuse of antimicrobials in livestock and aquaculture production systems and lack of surveillance of antimicrobial use. Priority interventions include strengthening of regulation and control of antimicrobial use and increasing awareness on rational use of antimicrobials and the dangers of self-medication with antibiotics.

To ensure inclusion, all important actors in the value chain need to be identified and invited for meetings where they can participate in exchange of information. In this regard, stakeholder mapping and the use of gender-focused approaches will be important.

The identified partner groups to work with included government ministries, universities, hospitals, public health institutes, pastoralists, the private sector, pharmaceutical companies and food manufacturers.

As the meeting ended, Vessaly Kallo, deputy director of animal health at the Directorate of Veterinary Services, lauded the proposed CGIAR One Health initiative. He noted that the initiative’s activities would support the implementation of a One Health multisectoral platform in Côte d’Ivoire.

Once approved, the CGIAR One Health initiative will start in January 2022 and run for an initial three years.

Action for Animal Health is a coalition of multilateral organizations, non-governmental organizations and research institutes with expertise in animal, human and environmental health. The coalition advocates for increased investment in strong and resilient animal health systems that protect people, animals and the planet. The International Livestock Research Institute (ILRI), one of 15 CGIAR research centres, is a member of the coalition.

Ahead of this year’s G20 Health Ministers’ Meeting, scheduled for 5–6 September 2021, the Action for Animal Health coalition urges G20 countries to support four transformative actions for stronger animal health systems:

  1. Ensure communities have access to animal health services
  2. Increase and upskill the animal health workforce globally
  3. Improve access to safe medicines and vaccines for animals
  4. Strengthen early warning disease surveillance systems that are effective from the community level upwards

With 75% of new diseases emerging from animals, the G20 must fund and implement a One Health approach to prevent future pandemics. A One Health approach recognizes that the health of people is closely linked to the health of animals and their shared environment. It involves the collaborative efforts of multiple disciplines and sectors to prevent and control diseases. It is especially useful for managing zoonoses, diseases transmitted between animals and people.

Zoonoses, like COVID-19, and antimicrobial resistance are among the major global public health threats facing humanity. The G20 urgently needs to invest in animal health to strengthen and secure global health systems and build resilience to future health challenges.

  • environment (water and wildlife interfaces); and
  • economics, governance and behaviour.

The work package leaders presented briefly on the goals of their respective work packages, giving examples of planned innovations under each.

Bernard Bett, ILRI senior scientist and head of the ILRI-hosted One Health Centre in Africa, outlined the two main objectives of the zoonoses work package: pre-empting the spread of zoonoses at the wildlife–livestock interface and reducing the incidence of zoonotic pathogens associated with poverty. Among other innovations, the work package plans to map the risk of key endemic zoonoses and develop diagnostic kits for surveillance of zoonoses.

Hung Nguyen explained that the food safety work package aims to reduce the burden of foodborne disease in traditional (informal) food value chains, with a focus on animal-source foods and other perishables such as fruits and vegetables. Planned innovations include training and certification of food handlers and traders, promotion of consumer demand for safe food, and behavioural nudges to encourage safe food handling practices.

Arshnee Moodley, who heads the ILRI-hosted CGIAR Antimicrobial Resistance Hub, noted that antimicrobial resistance is a silent pandemic and many low- and middle-income countries do not have effective surveillance programs, resulting in lack of data on the burden of antimicrobial resistance. She however noted that Ethiopia has a national action plan on antimicrobial resistance. The work package on antimicrobial resistance will focus on reducing antimicrobial use in crop, fish and livestock production systems and reducing antimicrobial transmission from animals to people through food. Planned innovations include the generation of evidence on the economic impact of interventions to reduce antimicrobial use and the development of tools to help farmers use antimicrobials more prudently.

In his overview of the environment work package, Javier Mateo-Sagasta, senior researcher at IWMI, noted that water is a key connector between people, livestock and ecosystems and so the focus will be on improving land use and water management to reduce health risks such as antimicrobial residues and zoonotic pathogens. Approaches will include recovery and reuse of animal waste to prevent water pollution and promotion of good practices to ensure the safe use of marginal quality water.

Vivian Hoffmann, senior research fellow at IFPRI, explained that the goal of the economics, governance and behaviour work package is to understand the drivers of people’s behaviour within food systems and the impact of policies and governance approaches on this behaviour. An example of an innovation under this work package is a performance management system for government officials responsible for implementing surveillance and enforcing regulations on antimicrobial use or food safety. Another innovation is a system to ensure inclusion of small-scale farmers, traders, food vendors and vulnerable groups so that they benefit from One Health outcomes.

During parallel group discussions on the zoonoses, food safety and antimicrobial resistance work packages, the participants gave feedback on the main One Health challenges, priority interventions, actions to ensure inclusion and partner institutions in Ethiopia.

With regard to control of zoonoses, some of the key challenges identified were weak surveillance systems, shortages of drugs and vaccines, budgetary constraints and lack of laboratory infrastructure. Priority interventions include generation of data on the burden of zoonoses, strengthening of institutions involved in One Health, and capacity building to improve the prevention and control of zoonoses within the framework of One Health.

Among the main food safety challenges identified were food adulteration, low laboratory capacity, poor law enforcement and weak food safety systems. Priority interventions include strengthening of food safety surveillance systems, development of a national food safety strategy and strengthening of legal frameworks.

Regarding antimicrobial resistance, some of the key challenges identified were inadequate surveillance in livestock production systems, high burden of infectious diseases and irrational use of antimicrobial drugs. To address these challenges, there is a need to develop antimicrobial resistance surveillance plans for human health, animal health and food safety. In addition, public awareness on antimicrobial resistance is needed to ensure prudent use of antimicrobials.

Among the suggested actions to ensure inclusion were stakeholder mapping, group-based community approaches, addressing gender in community conversations, and increased advocacy to engage policymakers.

The identified partner groups to work with included government ministries, national and international research organizations, universities, bureau of standards, farmer groups, women’s groups, consumer associations and the media.

As the meeting ended, Feyesa Regassa, lead researcher at the Ethiopian Public Health Institute and chair of Ethiopia’s National One Health Committee, expressed his appreciation to the initiative design team for their support on One Health, specifically food safety, zoonoses and antimicrobial resistance. He also expressed gratitude to all the participants.

‘This is a valuable opportunity for Ethiopia to collaborate,’ he noted.

In her closing remarks, Siboniso Moyo, the ILRI director general’s representative in Ethiopia, thanked everyone for their participation towards achieving the objective of helping the One Health initiative design team as it formulates key interventions and work packages. She expressed her appreciation to the organizing team, facilitators and all who worked behind the scenes to plan for the meeting. She looked forward to working together in this and other initiatives with partners in Ethiopia towards improved human, animal and environment health.

Once approved, the CGIAR One Health initiative will start in January 2022 and run for an initial three years.

Arshnee Moodley, who heads the ILRI-hosted CGIAR Antimicrobial Resistance Hub, said that the antimicrobial resistance work package will focus on reducing the burden of antimicrobial resistance by promoting the prudent use of antimicrobials in crop, fish and livestock production systems. In this regard, surveillance of antimicrobial use and antimicrobial resistance in animals and animal-source foods is important. Additionally, there is a need to generate and communicate evidence on the costs and benefits of rational use of antimicrobials to support uptake of interventions by farmers and policymakers.

In his overview of the environment work package, Javier Mateo-Sagasta, senior researcher at IWMI, noted that water is a key connector between people, livestock and ecosystems and so the focus will be on improving land use and water management to reduce health risks such as antimicrobial residues and zoonotic pathogens.

During parallel group discussions on the zoonoses, food safety and antimicrobial resistance work packages, the participants gave feedback on the main One Health challenges, priority interventions, actions to ensure inclusion and partner institutions in Kenya.

With regard to control of zoonoses, among the key challenges identified were cross-sectoral coordination among government bodies and lack of adequate funding. Capacity development was noted as an area that needs to be strengthened at all levels. There is also a need to better understand the risks of zoonoses spillover from wildlife to livestock in boundary areas.

The main food safety challenges identified included aflatoxins, chemical contamination and inadequate capacity for effective food inspection. Capacity development was identified as a priority food safety intervention, in addition to strengthening of food safety legal frameworks at national and county levels, increasing consumer awareness and improving water quality and infrastructure.

The discussion on antimicrobial resistance identified the need for evidence on the costs and benefits of reducing antimicrobial use in order to get buy-in from policymakers. Regulation of veterinary drugs is another challenge, as is the enforcement of proper use of antimicrobials. There is a need for consumer education and strengthening of extension and veterinary services.

The use of participatory approaches and tailoring of communication to suit specific target audiences were suggested as some of the ways of ensuring inclusion of small-scale farmers, traders, vendors, women and youth at all levels of the value chain.

The identified partner groups to work with included government ministries of agriculture, health and environment (at national and county levels); national and international research organizations; universities; bureau of standards; farmer/producer groups; women’s groups; consumer organizations and civil-society organizations.

As the meeting ended, Sam Kariuki, acting director general of the Kenya Medical Research Institute, summed up the discussions as having been very engaging and fruitful. He urged the team to focus on practical approaches and leverage on low-cost, effective technologies to ensure that the planned interventions achieve positive impact among farmers on the ground.

‘Think big, but act local,’ he advised.

In his closing remarks, Dieter Schillinger thanked the participants for their contributions and said that the team would build on the ideas discussed and use them to fine-tune the development of the research initiative. He further assured the participants of CGIAR’s continued collaboration with and support of One Health partners in Kenya towards improved human, animal and environment health.

Once approved, the CGIAR One Health initiative will start in January 2022 and run for an initial three years.

The world’s largest publicly-funded agricultural research partnership, CGIAR, is currently developing a series of initiatives to implement its 2030 research and innovation strategy that was launched in early 2021.

The research initiatives are designed to create lasting impact in five key areas:

  • nutrition, health and food security;
  • poverty reduction, livelihoods and jobs;
  • gender equality, youth and social inclusion;
  • climate adaptation and mitigation; and
  • environmental health and biodiversity.

One of these research initiatives, Protecting human health through a One Health approach, aims to improve the prevention and control of antimicrobial resistance, foodborne diseases and zoonoses in seven target countries: Bangladesh, Côte d’Ivoire, Ethiopia, India, Kenya, Uganda and Vietnam.

The development of the One Health initiative is being led by a team of scientists from four CGIAR research centres — the International Food Policy Research Institute (IFPRI), the International Livestock Research Institute (ILRI), the International Water Management Institute (IWMI) and WorldFish — in collaboration with external research partners from Centre Suisse de Recherches Scientifiques en Côte d’Ivoire, EcoHealth Alliance and the University of Liverpool.

To ensure alignment of the proposed initiative with national priorities, the team convened a series of online consultative meetings with research collaborators to gain insights on the main One Health priorities, challenges, interventions and partner organizations in the respective countries.

The Uganda meeting, hosted by ILRI, took place on Wednesday 4 August 2021, bringing together some 20 participants from the Ministry of Agriculture, Animal Industry and Fisheries as well as research organizations.

Dieter Schillinger, ILRI’s deputy director general for biosciences research and development, opened the meeting with a word of welcome and an overview of CGIAR’s 2030 research and innovation strategy that will guide the implementation of the 33 new research initiatives, including that on One Health—the focus of the online consultation.

He mentioned that the development of the One Health research initiative is a collaborative process and ILRI is working closely with other CGIAR research centres as well as external partners from research and academia, including those represented at the meeting. He highlighted the ongoing Boosting Uganda’s Investment in Livestock Development (BUILD) project as an example of ILRI’s research collaboration with partners in Uganda. He therefore welcomed feedback and suggestions from the participants to ensure the research of the One Health initiative is relevant and impactful.

Hung Nguyen, co-leader of ILRI’s Animal and Human Health program, followed with an overview of the rationale of the One Health initiative, citing the need for a One Health approach to tackle the complexity of the global public health challenges posed by the rising incidence of antimicrobial resistance, foodborne diseases and zoonoses.

He then outlined the three main objectives of the One Health initiative, namely, to generate evidence for decision-making; evaluate impacts of One Health approaches; and scale up innovations into national policies and programs.

He further highlighted the initiative’s Theory of Change, explaining how the research outputs are expected to lead to specific development outcomes and impact by 2030, in line with the United Nations Sustainable Development Goals. The team estimates that between 4 million and 41 million cases of disease will be averted annually through the initiative’s efforts.

The initiative’s research activities will take place through five work packages:

  • zoonoses;
  • food safety;
  • antimicrobial resistance;
  • environment (water and wildlife interfaces); and
  • economics, governance and behaviour.

The work package leaders presented briefly on the goals of their respective work packages, giving examples of planned innovations under each.

Bernard Bett, ILRI senior scientist and head of the ILRI-hosted One Health Centre in Africa, outlined the two main objectives of the zoonoses work package: pre-empting the spread of zoonoses at the wildlife–livestock interface and reducing the incidence of zoonotic pathogens associated with poverty. Among other innovations, the work package plans to map the risk of key endemic zoonoses and develop diagnostic kits for surveillance of zoonoses.

Hung Nguyen explained that the food safety work package aims to reduce the burden of foodborne disease in traditional (informal) food value chains, with a focus on animal-source foods and other perishables such as fruits and vegetables. Planned innovations include training and certification of food handlers and traders, promotion of consumer demand for safe food, and behavioural nudges to encourage safe food handling practices.

He further gave an overview of the antimicrobial resistance work package which will focus on reducing the burden of antimicrobial resistance by promoting the prudent use of antimicrobials in crop, fish and livestock production systems. In this regard, surveillance of antimicrobial use and antimicrobial resistance in animals and animal-source foods is important. Additionally, there is a need to generate and communicate evidence on the costs and benefits of rational use of antimicrobials to support uptake of interventions by farmers and policymakers.

In his overview of the environment work package, Javier Mateo-Sagasta, senior researcher at IWMI, noted that water is a key connector between people, livestock and ecosystems and so the focus will be on improving land use and water management to reduce health risks such as antimicrobial residues and zoonotic pathogens. Approaches will include recovery and reuse of animal waste to prevent water pollution and promotion of good practices to ensure the safe use of marginal quality water.

Vivian Hoffmann, senior research fellow at IFPRI, explained that the goal of the economics, governance and behaviour work package is to understand the drivers of people’s behaviour within food systems and the impact of policies and governance approaches on this behaviour. An example of an innovation under this work package is a performance management system for government officials responsible for implementing surveillance and enforcing regulations on antimicrobial use or food safety. Another innovation is a system to ensure inclusion of small-scale farmers, traders, food vendors and vulnerable groups so that they benefit from One Health outcomes.

During parallel group discussions on the zoonoses, food safety and antimicrobial resistance work packages, the participants gave feedback on the main One Health challenges, priority interventions, actions to ensure inclusion and partner institutions in Uganda.

With regard to control of zoonoses, the implementation of policies and regulations was identified as a key challenge. Outdated legislation and lack of adequate funding were also mentioned as important constraints. Community sensitization and increased awareness of zoonotic diseases are among the priority interventions that were identified.

The lack of adequate capacity for sampling, surveillance and laboratory testing was identified as a key challenge to effective management of food safety in the country. There is also low enforcement of existing food safety policies and regulations. There is a need for evidence on the burden of foodborne disease in the country. In addition, the food safety regulatory framework should be reviewed.

The lack of data on the risks of antimicrobial resistance in the country was identified as a major gap. In addition, there is weak enforcement of regulations to tackle antimicrobial resistance.

Gender value chain analysis and policy support for disadvantaged groups were suggested as some of the ways of ensuring inclusion of farmers, traders, women and youth. In addition, training modules should be gender-sensitive and appropriately packaged according to the literacy levels of the target audiences.

The identified partner groups to work with included government ministries of agriculture, health, water and environment; national and international research organizations; bureau of standards; government and private food safety laboratories; farmer groups; women’s groups and veterinary pharmaceutical companies.

As the meeting ended, Juliet Sentumbwe, director of animal resources at the Ministry of Agriculture, Animal Industry and Fisheries, thanked the participants for their active contributions. She observed that the focal areas of the One Health initiative are very pertinent for Uganda and well aligned with the country’s national action plan for health security through which various One Health activities are being implemented.

She also noted the importance of multi-stakeholder approaches to ensure inclusion of all groups. A One Health coordinating office will be useful in this regard.

‘We need to put in place structures that will bring all the stakeholders together,’ she advised.

She welcomed the opportunity to partner with CGIAR in the development and implementation of the One Health initiative and assured the team of the continued support of partners in Uganda.

In his closing remarks, Ben Lukuyu, ILRI’s country representative in Uganda, thanked everyone for attending and participating actively in the discussions. He particularly acknowledged the support of the Ministry of Agriculture and looked forward to further collaboration with One Health partners in Uganda towards improved human, animal and environment health.

Once approved, the CGIAR One Health initiative will start in January 2022 and run for an initial three years.

World Zoonoses Day, celebrated annually on 6 July, commemorates the day in 1885 when Louis Pasteur successfully administered the first vaccine against a zoonotic disease. It is also a day to raise public awareness of the risk of zoonotic diseases and how to effectively prevent and control them.

The International Livestock Research Institute (ILRI) has a wealth of research expertise on zoonoses. Through its Animal and Human Health program, ILRI works with national and international partners to improve the control of zoonotic diseases through various approaches such as risk mapping and risk targeting, modelling of zoonotic pandemics, decision-support tools and advice on vaccination strategies. The program also generates evidence for policymakers on the cost and impact of zoonoses and the benefits of their prevention.

Our collaborative research projects on zoonoses include examining zoonotic infections among livestock and the farmers who keep them; developing optimal vaccination strategies for Rift Valley fever in East Africa; studying the epidemiology, ecology and socio-economics of disease emergence in Nairobi; developing a surveillance program for zoonoses in livestock in Kenya; identifying anthrax hotspots and ecological risk factors in Kenya and determining the burden of Rift Valley fever, brucellosis and Q fever co-infection in people, livestock and wildlife in Kenya.

Makara market in Phnom Penh, Cambodia

Emerging zoonotic diseases can spread from animals to people where there is an interface allowing pathogens to jump the species barriers. Crowded conditions, where different species intermingle, increase these interfaces. Zoonotic diseases exert a significant burden on human health and have considerable socioeconomic impact worldwide.

The World Health Organization reports that there are currently more than 200 known types of zoonotic diseases. The health and economic cost of these diseases falls largely on poorer countries which bear 98% of the global burden of zoonoses.

In Asia, live animals as well as animal products are commonly sold in traditional markets, sometimes referred to as ‘live’ or ‘wet’ markets. The interaction of people, live domestic animals for sale, food products, and wild and scavenging animals at these markets creates a risk for emerging infectious diseases.

Live and wet markets have been linked to the emergence of zoonotic viruses, for example, avian influenza viruses and coronaviruses. These markets are also an important source of foodborne pathogens.

A new study published in Trends in Microbiology (July 2021) presents data on the global impact of live and wet markets on the emergence of zoonotic diseases.

The study discusses how benefits can be maximized and risks minimized and concludes that current regulations should be implemented or revised to mitigate the risk of new diseases emerging in the future.

In addition, improved biosecurity measures and continuous monitoring are needed to reduce the risks of zoonotic disease transmission.
