Landscape of H5 Infections in ASEAN Region: Past Insights, Present Realities, & Future Strategies.

The H5 Avian Influenza A virus infection has emerged as a global concern, particularly in the ASEAN region. This viral infection poses a significant threat to the poultry industry, public health, and regional economies. This region's reliance on poultry production and the zoonotic potential of H5 subtypes, with documented transmission to various mammalian species and humans, necessitates proactive mitigation strategies. Over the years, comprehensive efforts such as surveillance, vaccination programs, biosecurity measures, and public health education have been implemented to keep outbreaks at bay. In this review, we provide a thorough overview of the H5 infections in the ASEAN region, focusing on the unique challenges and successes in this geographic area. We analyze epidemiological trends, including specific high-risk populations and transmission patterns, and assess the socioeconomic impact of H5 outbreaks on local communities. We also examine regional responses, highlighting innovative surveillance programs, vaccination strategies, and biosecurity measures implemented to control the virus. Furthermore, we explore the crucial role of the One Health approach, emphasizing interdisciplinary collaboration between human, animal, and environmental health sectors. Finally, we discuss future strategies for prevention and control, including the importance of regional cooperation in combating this evolving threat. Through this, we aim to provide valuable insights to the public, policymakers, and researchers involved in tackling H5 infections globally.
