November 3, 2020, marks the fifth annual One Health Day, a global campaign that celebrates and brings attention to the need for a One Health approach to address shared health threats at the human-animal-environment interface.

Never before has the significance of this day been more important. The moment is NOW for global participation by every individual to participate in whatever way possible in the efforts to address the compelling needs for our planetary survival.

Since its inception in 2016, One Health Day has provided a platform which gives scientists and advocates a powerful voice for moving beyond current provincial approaches to emerging zoonotic infectious diseases, antimicrobial resistance, climate change, environmental pollution, food safety, comparative/ translational medicineand many other problems, to a holistic default way of doing business.

One Health Day was launched by three leading international One Health groups, the One Health Commission, the One Health Initiative Autonomous pro bono Team, and the One Health Platform Foundation, global One Health Day has grown into an annual platform for One Health advocates around the world to educate in their regions about One Health and One Health challenges. Anyone, from academic to private to corporate to governmental agencies can lead One Health Day events and are urged to register them to get on the annual official One Health Day map.

The One Health Initiative, of which we are a supporting member, is a movement to forge co-equal, all-inclusive collaborations between physicians, osteopathic physicians, veterinarians, dentists, nurses, and other scientific-health and environmentally related disciplines, including the American Medical Association, American Veterinary Medical Association, American Academy of Pediatrics, American Nurses Association, American Association of Public Health Physicians, the American Society of Tropical Medicine and Hygiene, the Centers for Disease Control and Prevention (CDC), the United States Department of Agriculture (USDA), and the U.S. National Environmental Health Association (NEHA). Additionally, more than 979 prominent scientists, physicians, and veterinarians worldwide have endorsed the initiative.
