This editorial offers a frontline perspective on Poland’s 2024 flood (based on ~170 paged report) through a One Health lens, intertwining veterinary and human epidemiology, environmental science, and real-time infodemic management. Drawing on field experience—from coordinating rescue actions, post-exposure vaccinations and ad-hoc water-quality testing to monitoring social-media–driven risk narratives—the piece illustrates how pandemic-era misinformation patterns resurfaced during the disaster and influenced operational decisions. By situating practical lessons within a concise evidence framework, we seek to catalyse dialogue among clinicians, public-health officers, and disaster scientists, fostering more integrated readiness for future high-impact events.
