Introduction

The One Health approach is crucial for effectively addressing emerging zoonotic threats and potential pandemics. It emphasizes the interconnectedness of human, animal, and environmental health, advocating for collaborative strategies across disciplines. This comprehensive view allows for earlier detection, more integrated surveillance, and better-coordinated responses, ultimately bolstering global health security against future outbreaks [1].

The urgency for a One Health approach in global health security is undeniable. With increasing human-animal-environment interfaces, understanding and addressing health threats requires cross-sectoral collaboration. This perspective moves beyond compartmentalized responses, fostering comprehensive solutions for complex challenges like emerging infectious diseases and biothreats [3].

In our current Anthropocene era, where human activity profoundly impacts ecosystems, advancing One Health is critical for global health security. This approach helps anticipate and mitigate risks from emerging infectious diseases by understanding how environmental changes influence pathogen spillover from animals to humans, thus safeguarding public health [5].

Effective pandemic preparedness in regions like Sub-Saharan Africa greatly benefits from a One Health perspective. Recognizing that human health outcomes are intrinsically linked to animal health and environmental factors helps tailor interventions that are culturally relevant and environmentally sustainable. This integrated approach is vital for building resilient health systems capable of mitigating novel disease threats [2].

Integrating One Health into outbreak investigations significantly strengthens pandemic preparedness. By considering human, animal, and environmental factors simultaneously, we can identify root causes of disease emergence more effectively. This holistic view enhances surveillance, early warning systems, and rapid response capabilities, making global health security more robust [4].

The COVID-19 pandemic underscored the vital importance of the One Health approach in preventing and controlling zoonotic diseases. Lessons from the pandemic highlight the necessity of robust collaboration between human, animal, and environmental health sectors. Moving forward, sustained investment in One Health strategies is essential for effective preparedness and response to future outbreaks [6].

The COVID-19 pandemic also served as a stark lesson, underscoring the critical need for a One Health approach in global health security. It highlighted how interconnected human, animal, and environmental health are, and that neglecting any one aspect can lead to widespread crises. Prioritizing One Health is essential for building resilient defense against future pandemics [9].

Beyond pandemic response, the One Health framework plays a crucial role in strengthening global biosecurity and biodefense. By fostering integrated surveillance, early warning systems, and joint risk assessments across human, animal, and environmental domains, it enhances our collective ability to prevent, detect, and respond to both natural and deliberate biothreats [8].

Translating One Health research into actionable policy and real-world impact faces specific challenges, yet offers significant opportunities. Addressing these gaps, such as improving inter-sectoral communication and funding mechanisms, is key to accelerating the practical application of One Health principles. This ensures a more effective and coordinated defense against biothreats [7].

Global initiatives for addressing emerging infectious diseases increasingly adopt a One Health framework, yet significant challenges remain. This review explores the current landscape, identifying both progress and obstacles in implementing integrated approaches. A deeper commitment to cross-sectoral collaboration and resource allocation is necessary to fully leverage One Health in mitigating future biothreats [10].

Description

The One Health paradigm is a foundational concept for understanding and confronting modern health challenges, particularly emerging zoonotic threats and potential pandemics. It operates on the principle that human, animal, and environmental health are inextricably linked. This interconnectedness demands a unified, collaborative approach across various scientific and societal disciplines, moving away from siloed responses. The outcome of such an integrated strategy is a significantly bolstered global health security, enabling earlier detection of threats, more effective surveillance systems, and better-coordinated emergency responses [1, 3]. In our current geological epoch, the Anthropocene, human activities exert profound impacts on ecosystems. Recognizing this, the One Health approach becomes even more critical. It acts as a preventive shield, helping us anticipate and mitigate risks stemming from emerging infectious diseases by understanding how environmental shifts facilitate pathogen transmission from animal populations to humans, thereby safeguarding public health globally [5].

A key application of the One Health framework is in strengthening pandemic preparedness and response. For instance, in regions like Sub-Saharan Africa, adopting a One Health perspective allows for the development of interventions that are not only effective but also culturally relevant and environmentally sustainable, recognizing the deep links between health outcomes and local ecological and social factors. This integrated thinking is essential for constructing resilient health infrastructures capable of handling novel disease threats effectively [2]. Furthermore, when it comes to outbreak investigations, incorporating One Health principles from the outset proves invaluable. By simultaneously evaluating human, animal, and environmental factors, researchers and public health officials can more accurately pinpoint the root causes of disease emergence. This holistic perspective significantly boosts the efficacy of surveillance, enhances early warning systems, and accelerates rapid response capabilities, making global health security far more robust against unforeseen challenges [4].

The recent COVID-19 pandemic served as a stark and undeniable demonstration of One Health's crucial role in disease prevention and control. The crisis powerfully highlighted the imperative for robust and continuous collaboration between human, animal, and environmental health sectors. The lessons learned are clear: sustained investment in One Health strategies is not merely beneficial but absolutely essential for effective preparedness and responsive action to future outbreaks of zoonotic origin [6]. Indeed, the pandemic underscored just how deeply intertwined human, animal, and environmental health truly are, showing that neglect of any single component can precipitate widespread global crises. Therefore, making One Health a priority is fundamental to building a resilient defense against future pandemics and ensuring broader global health security [9]. Beyond emerging infectious diseases, the One Health framework is also vital for fortifying global biosecurity and biodefense. It promotes integrated surveillance, the establishment of sophisticated early warning systems, and joint risk assessments that span human, animal, and environmental domains. This collective capacity is crucial for preventing, detecting, and responding to both naturally occurring and deliberately introduced biothreats [8].

While global initiatives increasingly embrace the One Health framework for addressing emerging infectious diseases, implementing these integrated approaches still faces considerable challenges. Current reviews of the landscape reveal both significant progress and persistent obstacles. Overcoming these hurdles, such as improving inter-sectoral communication and securing adequate, sustained funding mechanisms, is paramount for accelerating the practical application of One Health principles into actionable policy and tangible real-world impact. This focused effort ensures a more effective and coordinated defense against complex biothreats [7, 10]. A deeper, more committed approach to cross-sectoral collaboration and judicious resource allocation is required to fully harness the potential of One Health in mitigating future global health security risks.

Conclusion

The One Health approach stands as a crucial framework for effectively tackling emerging zoonotic threats and potential pandemics. It underscores the profound interconnectedness of human, animal, and environmental health, advocating for collaborative strategies across all relevant disciplines. This comprehensive perspective significantly bolsters global health security by enabling earlier detection of threats, implementing more integrated surveillance systems, and facilitating better-coordinated responses worldwide [1, 3]. It proves essential for robust pandemic preparedness, particularly in regions like Sub-Saharan Africa, where it helps tailor culturally and environmentally sustainable interventions. Moreover, integrating One Health into outbreak investigations allows for more effective identification of disease emergence root causes, enhancing overall rapid response capabilities [2, 4]. The current Anthropocene era, marked by substantial human impact on ecosystems, further highlights the critical role of One Health in anticipating and mitigating risks from emerging infectious diseases by understanding environmental influences on pathogen spillover, thus safeguarding public health [5]. The COVID-19 pandemic provided undeniable proof of One Health’s vital importance, showcasing the necessity of robust collaboration between human, animal, and environmental health sectors for preventing and controlling zoonotic diseases and building resilient defenses against future crises [6, 9]. The framework also plays a critical role in strengthening global biosecurity and biodefense through integrated surveillance, early warning, and joint risk assessments against both natural and deliberate biothreats [8]. While its adoption grows, significant challenges persist in translating One Health research into actionable policy and real-world impact, demanding improved inter-sectoral communication and dedicated resource allocation to fully realize its potential in mitigating future biothreats [7, 10].
