Introduction

“Like it or not, we humans are bound up with our fellows, and with the other plants and animals all over the world. Our lives are interwined”- Carl Sagan

The threat posed by zoonotic infections looms large over global health in an interconnected society. Zoonoses, contagious illnesses that can be passed from animals to people, have historically resulted in serious public health catastrophes. The development of zoonotic illnesses like SARS, MERS, Ebola, and—most significantly—the COVID-19 pandemic has brought this need for an all-encompassing strategy to prevent and control these illnesses to light. One World, One Health is a philosophy that emphasises the value of cross-sectoral and international cooperation in addressing zoonotic concerns while recognising the interdependence of human, animal, and environmental health.

The emergence and Evolution of One World, One Health Concept

The concept of “One World, One Health” has its roots in the late 19th and early 20th centuries, when scientists and medical professionals began to recognise the potential connections between animal and human diseases. But it wasn’t until the 1990s that the present idea of “One Health” started to take shape. The Wildlife Trust and the Wildlife Conservation Society (WCS) organised a meeting in 1999 to discuss the relationship between the wellbeing of wildlife and people. The necessity of interdisciplinary cooperation in the fight against newly developing infectious illnesses was recognised in a big way at this event.

The Wildlife Conservation Society (WCS), the World Health Organisation (WHO), the Food and Agriculture Organisation (FAO), and the World Organisation for Animal Health (OIE) joined forces in 2007 to publicly recognise the significance of One Health in battling zoonotic illnesses. Gaining acceptance and backing from significant international organisations was made possible because to this tripartite cooperation. In order to address health problems at the interface of humans, animals, and ecosystems, this tripartite cooperation placed a strong emphasis on a “One Health” approach.

The early 2000s zoonotic disease outbreaks of H5N1 avian influenza and H1N1 influenza further demonstrated the necessity of a One Health approach. As zoonotic illnesses had the potential to quickly spread across species and borders, affecting human health, agriculture, and economy, One World, One Health began to receive widespread acceptance and acknowledgment in the years that followed. The need of interdisciplinary collaboration in disease surveillance, research, and public health interventions was emphasised by numerous nations and international organisations as they incorporated One Health ideas into their policies and programmes (CDC, 2022).

Impacts of Zoonosis on public health and socioeconomic stability

Public health and socioeconomic stability are significantly impacted by zoonoses. These illnesses have a wide spectrum of effects that can harm people, communities, and even countries.

Public Health Impact:

Zoonotic illnesses can cause serious illness and even death in both humans and animals. A sudden increase in infections brought on by zoonoses outbreaks can strain healthcare systems and resources. Particularly susceptible populations, such as the elderly, those with impaired immune systems, and children, may bear a disproportionately heavy burden of zoonotic infections. The financial burden of zoonoses on healthcare systems can put a strain on finances and reduce the amount of resources available for other health needs. Zoonotic outbreaks can make people fearful, anxious, and stressed out, which can lead to problems with mental health and occasionally even have long-term psychological effects on people and communities (Meslin et al., 2000).

Socioeconomic Impact:

Zoonotic epidemics can put a strain on healthcare systems, divert resources away from necessary healthcare services, and cause delays or cancellations of normal medical operations. The spread of an infectious illness can have a significant impact on incomes in the agricultural, livestock, and wildlife tourism industries. Reduced economic activity and income loss may result from quarantine procedures, travel limitations, and infection-related anxiety. Additionally, it may cause supply chains to be disrupted, have an influence on exports and imports, and result in financial losses for companies and industries. Countries may apply trade and travel restrictions in an effort to stop the spread of illnesses. In addition to raising healthcare expenses, zoonoses have a negative impact on the economy due to decreased productivity, lower worker engagement, and reduced consumer purchasing (Panth, 2017). Global economic crises could be brought on by zoonotic illnesses, as was the case during the COVID-19 pandemic.

The Core Principles of One World One Health: Its role in Preventing Zoonosis

One World, One Health’s fundamental tenets are centred on the knowledge that human, animal, and environmental health are interrelated and that tackling health issues necessitates an interdisciplinary, collaborative approach. One World, One Health methods are implemented in accordance with following guiding principles.

Interdisciplinary Collaboration and Governance:

Interdisciplinary collaboration is necessary for experts from various fields to work together to address complex health concerns at the intersection of humans, animals, and ecosystems. Effective government structures and policies are essential to foster cooperation between various sectors and to enable efficient collaboration.

 

Early Detection and Surveillance Systems:

Strong surveillance systems are essential for tracking disease patterns, spotting emerging threats, and tracking the transfer of infectious agents between species in both human and animal populations. The capacity to react swiftly and successfully to zoonotic threats is improved by timely reporting and data exchange between pertinent authorities and groups.

Preparedness and Rapid Response Mechanisms:

Having emergency preparation measures in place is essential for quick and efficient responses to zoonotic outbreaks. These plans include detailed procedures for locating, assessing, and managing suspected zoonotic diseases as well as guidelines for implementing control measures.

Research and Innovation in Zoonotic Disease Prevention:

Understanding the dynamics of zoonotic illnesses, including their causes, transmission routes, and risk factors, requires extensive research. The creation of efficient prevention and control techniques, such as vaccines, diagnostics, and treatments, is facilitated by ongoing research and innovation.

The Role of Environmental Conservation and Sustainable Practices:

In order to stop the spread of zoonotic diseases, One World, One Health emphasises the necessity of preserving healthy ecosystems. To minimise contacts between humans and animals and the risk of disease transmission, it is essential to conserve biodiversity and practise sustainable agriculture. The health of the entire ecosystem, which is strongly connected to the wellbeing of people and animals, is enhanced by protecting natural habitats and species (OHHLEP, 2022).

Successful Case Studies of One World, One Health Implementation

The One World, One Health approach has demonstrated its effectiveness in preventing and controlling zoonotic diseases through collaborative efforts across human, animal, and environmental health sectors. Countries like Costa Rica, Thailand, and Sri Lanka have seen notable successes in reducing human rabies cases through these integrated approaches. Countries such as Vietnam and Indonesia have established collaborative systems involving health authorities, veterinary agencies, and wildlife experts to detect and control avian influenza in both domestic and wild bird populations. India has implemented several successful One Health approaches to address zoonotic diseases and improve public health outcomes. Some of the notable One Health implementations in India are:

Nipah Virus Outbreak Response (2018): In 2018, India faced a Nipah virus outbreak in the state of Kerala, which raised significant public health concerns. The Nipah virus is a zoonotic pathogen transmitted to humans from fruit bats, and it can cause severe respiratory and neurological diseases. In response to the outbreak, India adopted a One Health approach involving collaboration between health authorities, veterinary experts, wildlife experts, and local communities. The response included surveillance and monitoring of both human and animal populations to detect and control the spread of the virus. Rapid containment measures were implemented, such as isolation of infected individuals, contact tracing, and community awareness campaigns. The One Health approach played a crucial role in managing the outbreak, preventing further transmission, and minimizing the impact on public health.

Avian Influenza Surveillance and Control: India has also been proactive in implementing One Health strategies to monitor and control avian influenza outbreaks. India has established a collaborative system involving health authorities, veterinary agencies, and wildlife experts to detect and manage avian influenza in both domestic and wild bird populations. The One Health approach emphasizes early detection through active surveillance and monitoring of bird populations. Control measures are implemented promptly in areas with outbreaks to prevent further spread to humans and other birds. Public awareness campaigns are also conducted to educate people about the risks associated with handling infected birds or consuming contaminated poultry products.

Brucellosis Control Program: India has implemented a Brucellosis Control Program, which follows a One Health approach to address the disease burden in both humans and animals. The program focuses on vaccination campaigns for livestock to reduce the prevalence of brucellosis in the animal population. Simultaneously, awareness campaigns are conducted to educate farmers and herders about the risks of brucellosis and preventive measures. The program also emphasizes collaboration between health authorities and veterinary agencies to ensure a coordinated response in managing human cases and controlling the disease in animals.

Integrated Disease Surveillance Program (IDSP): India’s Integrated Disease Surveillance Program (IDSP) is another example of successful One Health implementation. IDSP is a comprehensive disease surveillance system that monitors both human and animal diseases. It involves collaboration between health authorities, veterinary experts, and environmental agencies to detect and respond to disease outbreaks promptly. The IDSP system uses a network of laboratories and healthcare facilities to collect data on disease incidence and trends. This data is shared with relevant sectors to identify potential zoonotic threats and implement appropriate preventive measures. The One Health approach through IDSP has been effective in enhancing India’s capacity to detect and control disease outbreaks, including zoonoses.

Challenges and Barriers to One World, One Health Implementation

Implementing the One World, One Health approach, despite its potential benefits, comes with various challenges and barriers that can hinder its successful implementation. Understanding these challenges is crucial for developing effective strategies to overcome them and strengthen the One World, One Health approach. Some of the key challenges and barriers are:

Education and public awareness are essential in the One World, One Health approach as education helps people understand the risks of zoonotic diseases and how they can be transmitted from animals to humans. Public awareness campaigns can highlight high-risk behaviours, such as handling sick animals or consuming unsafe animal products, and promote preventive measures to reduce the risk of zoonotic transmission. Public awareness in one health can educate individuals, communities, and tourists about responsible animal and wildlife interaction such as avoiding contact with wild animals, refraining from consuming bushmeat or exotic pets, and adopting proper hygiene practices after interacting with animals.

Early reporting and enhanced disease surveillance can be done promptly by educating the public on one health approach. Public awareness efforts can foster a shared understanding of the interconnectedness of these sectors and encourage cooperation to address zoonotic threats effectively. Educating communities and stakeholders about zoonotic diseases empowers them to take proactive measures to protect themselves, their animals, and their environments. Public awareness campaigns can address stigma and misinformation related to zoonotic diseases. Misunderstandings about disease transmission or the origins of outbreaks can lead to fear and discrimination. Educating the public helps dispel myths and promotes fact-based information, fostering a more supportive and cooperative response to zoonotic threats. Public awareness initiatives can create a demand for policy change and increased resources to support One World, One Health efforts. When the public recognizes the importance of zoonotic disease prevention and understands the potential consequences of outbreaks, they are more likely to support policies that prioritize and fund One World, One Health programs.

Education and public awareness can contribute to fostering a culture of One Health, where individuals and communities recognize the shared responsibility in safeguarding human, animal, and environmental health. This cultural shift encourages interdisciplinary collaboration and reinforces the importance of One World, One Health in addressing global health challenges.

The Significance of International Collaboration in One World, One Health

International collaboration is of paramount importance in the One World, One Health approach. Zoonotic diseases do not recognize borders, and their emergence and spread can have global implications. To effectively prevent and control zoonotic diseases, countries must work together, share information, and coordinate response efforts. International collaboration in One World, One Health is significant for several key reasons:

• Early Detection and Rapid Response:

Zoonotic diseases can emerge in any part of the world and quickly spread across borders. By collaborating internationally, countries can share disease surveillance data and information about outbreaks in real-time. This early detection enables rapid response measures, including implementing travel restrictions, quarantine measures, and targeted interventions to contain the spread of the disease before it becomes a global pandemic.

• Sharing Knowledge and Expertise:

Different countries possess varying levels of expertise and experience in dealing with zoonotic diseases. International collaboration allows countries to share best practices, research findings, and innovative approaches to disease prevention and control. This exchange of knowledge enhances global capabilities in tackling zoonotic threats effectively.
