Introduction

The critical role of the 'One Health' approach in Southeast Asia for preventing and controlling emerging infectious diseases is paramount, highlighting the interconnectedness of human, animal, and environmental health, and advocating for robust collaborative strategies across sectors to effectively address major regional threats like zoonotic spillover and antimicrobial resistance [1].

These integrated efforts are fundamental to safeguarding public health. Climate change presents a significant and evolving challenge, offering an essential update for public health professionals on its multifaceted impacts. This includes a substantial influence on the emergence and re-emergence of infectious diseases, as altered ecological systems, extreme weather events, and shifts in vector distribution contribute to novel disease patterns, necessitating proactive and adaptable public health strategies globally [2].

Such adaptations are crucial for future resilience. Vaccine development against emerging viral diseases has seen remarkable recent advancements, utilizing innovative platforms such as mRNA and viral vector vaccines that have truly revolutionized rapid development. Despite this progress, persistent hurdles like immune evasion and the ongoing need for broad-spectrum protection against diverse viral strains remain significant challenges for researchers and public health initiatives [3].

Overcoming these hurdles is a key focus for global health security. Genomic surveillance plays a crucial role in detecting and responding to emerging pathogens with unprecedented speed and precision. High-throughput sequencing technologies provide powerful capabilities for real-time tracking of pathogen evolution and spread, yet significant challenges related to efficient data sharing, international standardization, and equitable global access to these advanced tools must be actively addressed [4].

Effective global cooperation is essential for maximizing their impact. Social and economic factors profoundly influence disease transmission, with valuable lessons gleaned from recent epidemics. These insights demonstrate how entrenched issues like poverty, inequality, urbanization, and inadequate access to healthcare infrastructure can severely exacerbate the spread of emerging infectious diseases, underscoring the urgent need for integrated public health interventions that specifically address these underlying social determinants of health [5].

A holistic approach is indispensable. The impact of wildlife farming on the emergence of zoonotic diseases is a significant area of research, revealing how close proximity and intensive practices inherently increase spillover risk and facilitate pathogen transmission from animals to humans. Consequently, the article advocates strongly for stricter regulations and a comprehensive 'One Health' approach to effectively mitigate future zoonotic threats [6].

Proactive measures in this domain are vital for prevention. Recent advancements in developing antiviral drugs targeting emerging viral infections encompass various therapeutic strategies, ranging from direct-acting antivirals to innovative host-targeted approaches. These developments highlight both their immense potential and the persistent challenges in combating novel and rapidly evolving viruses, emphasizing the pressing need for broad-spectrum antivirals and significantly accelerated drug discovery pipelines [7].

Innovation in this field is a continuous imperative. Infectious diseases and international travel pose complex current and future challenges. Global mobility inherently facilitates the rapid dissemination of pathogens, leading to imported cases and subsequent outbreaks in new regions. This phenomenon emphasizes the critical need for enhanced travel health advisories, robust surveillance at points of entry, and coordinated international responses to effectively mitigate cross-border transmission risks [8].

Preparedness at borders is more critical than ever. Decoding host-pathogen interactions in viral diseases offers truly crucial insights into the intricate mechanisms by which viruses manipulate host cells and skillfully evade immune responses. This deep understanding is absolutely vital for developing highly effective antiviral therapies and vaccines. Advanced genomic and proteomic tools are revolutionizing our ability to unravel these complex interactions, ultimately paving the way for targeted interventions that can save lives [9].

Precision medicine in this area holds great promise. Critically examining public health preparedness for future infectious disease threats, drawing valuable lessons from the devastating COVID-19 pandemic, unequivocally emphasizes the need for robust surveillance systems, rapid research and development capabilities, transparent and effective risk communication strategies, and the equitable distribution of resources. These pillars are essential to significantly enhance global readiness and response to emergent pathogens [10].

Learning from past experiences will fortify future defenses.

Description

The global landscape of emerging infectious diseases presents a persistent challenge, demanding multifaceted strategies that integrate public health, environmental science, and advanced technological interventions. A foundational principle in this effort is the 'One Health' approach, which recognizes the profound interconnectedness of human, animal, and environmental well-being. This perspective is particularly vital in regions like Southeast Asia, where collaborative strategies across sectors are essential to effectively address significant threats such as zoonotic spillover and the growing concern of antimicrobial resistance [C001]. Further reinforcing this, research into wildlife farming practices explicitly demonstrates how close proximity and intensive operations can heighten the risk of pathogens jumping from animals to humans. This directly necessitates stricter regulations and a comprehensive 'One Health' framework to preempt and mitigate future zoonotic threats [C006]. The holistic understanding fostered by 'One Health' is thus indispensable for proactive disease prevention.

Environmental shifts, particularly those driven by climate change, are fundamentally reshaping the epidemiology of infectious diseases. Public health professionals are increasingly tasked with understanding how altered ecological systems, the escalation of extreme weather events, and changes in vector distributions are contributing to the emergence and re-emergence of diseases [C002]. These environmental transformations create novel pathways for pathogen spread, demanding highly adaptable public health strategies to anticipate and respond to evolving disease patterns. Beyond environmental factors, socio-economic determinants play a critical, often exacerbating, role in disease transmission. Lessons from recent epidemics vividly illustrate how widespread poverty, systemic inequality, rapid urbanization, and inadequate access to vital healthcare infrastructure can significantly accelerate the spread of emerging infectious diseases. This reality underscores the urgent necessity for public health interventions that are not only medically sound but also deeply integrated with efforts to address these underlying social determinants of health [C005].

Technological advancements are revolutionizing our capacity to respond to and manage emerging pathogens. Genomic surveillance, for instance, has become a pivotal tool, leveraging high-throughput sequencing technologies to provide unparalleled capabilities for real-time tracking of pathogen evolution and geographic spread [C004]. Despite its immense potential, challenges persist in ensuring efficient global data sharing, standardizing methodologies, and achieving equitable access to these sophisticated tools across all nations. Parallel to surveillance, significant strides have been made in therapeutic and prophylactic development. The development of vaccines against emerging viral diseases has progressed remarkably, with innovative platforms like mRNA and viral vector vaccines dramatically accelerating development timelines. However, the ongoing struggle with immune evasion and the continuous need for broad-spectrum protection against diverse viral strains remain considerable hurdles [C003]. Similarly, the development of antiviral drugs targeting emerging viral infections shows promise, with various strategies ranging from direct-acting antivirals to host-targeted approaches. These developments highlight potential new avenues for treatment, yet emphasize the need for accelerated drug discovery pipelines to keep pace with rapidly evolving viruses [C007].

Understanding the intricate biology of infectious agents is also paramount. Deep dives into host-pathogen interactions in viral diseases are providing crucial insights into the mechanisms by which viruses manipulate host cells and effectively evade immune responses [C009]. This granular understanding, facilitated by advanced genomic and proteomic tools, is fundamental for developing highly effective antiviral therapies and vaccines that can precisely target viral vulnerabilities or bolster host defenses. As global interconnectedness increases, so too does the challenge of managing disease spread. International travel, while a cornerstone of modern society, unfortunately facilitates the rapid dissemination of pathogens, leading to imported cases and subsequent outbreaks in new regions [C008]. This global mobility necessitates enhanced travel health advisories, robust surveillance at points of entry, and coordinated international responses to effectively mitigate cross-border transmission risks.

Ultimately, effective public health preparedness for future infectious disease threats is a critical undertaking, learning invaluable lessons from the COVID-19 pandemic. This experience has unequivocally emphasized the need for resilient surveillance systems, robust rapid research and development capabilities, transparent and effective risk communication strategies, and the equitable distribution of resources globally [C010]. Strengthening these pillars is not merely a reactive measure but a proactive investment in global health security, ensuring a more coordinated and effective response to emergent pathogens on a worldwide scale. The confluence of these scientific, social, and logistical strategies forms the bedrock of our defense against future health crises.
