Effective emergency preparedness and response rely on understanding and addressing the specific needs and perspectives of affected communities. However, these communities are often underrepresented in decision-making processes, leading to reduced trust, missed opportunities, and suboptimal health outcomes. In the context of the Western Pacific Region, the World Health Organization (WHO) has recognized the urgent need to bridge this gap by incorporating behavioural science into emergency preparedness and response. This effort aligns with the broader goals of the Asia Pacific Health Security Action Framework (APHSAF) and reinforces WHO’s commitment to more inclusive, evidence-based emergency preparedness. To meet this need, the WHO Regional Office for the Western Pacific (WPRO) is advancing the BRIDGE approach—Behavioural Research and Intelligence for Directed Guidance in Emergencies. This approach aims to enhance the integration of behavioural insights into emergency response planning, ensuring that interventions are timely, trusted, and effective. A particular focus has been placed on improving infodemic management, especially in response to emerging and re-emerging infectious diseases such as mpox.    During health emergencies, the rapid spread of mis/disinformation and information voids can significantly hinder public health efforts. Addressing these challenges requires not just timely communication, but also a nuanced understanding of how communities perceive and respond to information. Through social listening, community engagement, and behavioural analysis, WPRO seeks to promote accurate health messaging, counter harmful narratives, and empower communities to make informed decisions that protect their health and wellbeing.   Kindly include WHO Bid Reference No. WPRO/2025-10/WHE/280706 in all submissions.
