From knowledge to action: the role of professional health associations on public health well-being in Ukraine.

Professional health associations increasingly serve as vital transnational actors in responding to global public health emergencies and shaping health system resilience. Their cross-border collaboration becomes especially critical in conflict-affected settings, where local infrastructure is overwhelmed, and international expertise, advocacy, and solidarity can bridge urgent gaps. In Ukraine, the intersection of war, health system disruption, and infectious disease threats has underscored the role of organizations such as the All-Ukrainian Association of Public Health Specialists (UPHA), the European Society of Clinical Microbiology and Infectious Diseases (ESCMID), the American Society for Microbiology (ASM), and the American Public Health Association (APHA). These associations contribute technical assistance, policy guidance, and emergency response and cultivate a shared professional culture and knowledge base that transcends national borders. While the role of professional health associations in routine healthcare delivery and advocacy has been previously explored in the literature, few publications have addressed their mobilization during acute crises-particularly in lower-resource or conflict settings. This comment responds to that gap by examining how professional associations act as platforms for coordinated response, capacity building, and health diplomacy during complex emergencies, with a specific focus on addressing infectious diseases in Ukraine. It draws on desk reviews, organizational reports, and authors' insights to inform how these associations support infection prevention, biosafety, antimicrobial resistance surveillance, and the development of a resilient public health workforce-issues of global relevance that demand collaborative solutions.
