More than 70% of (re-) emerging infectious diseases are from animal origin. Preventing epidemics requires bold action at the human-animal-environmental interface, in line with the One Health approach. Further to earlier One Health-focused EPI-WIN webinars, this webinar features voices from One Health professionals working on epidemic and pandemic prevention and preparedness. Ahead of One Health Day on 3 November, the discussion focuses on the sharing of experiences, research and examples from professionals from various backgrounds, field of expertise and sectors.
