One Health Day - One Health Commission

One Health Day


In 2020, 2021 and 2022, One Health Day celebrations were especially poignant. In the face of the COVID-19 pandemic, One Health is being recognized and embraced as needed now more than ever.

During the current pandemic, 'in person' One Health Day events are encouraged 'only' if careful COVID-19 prevention protocols are in place.

However, many possibilities exist for posters, YouTube, social media, radio and TV campaigns and online educational webinars to raise awareness of what One Health is and to educate about many One Health arenas.  The One Health Day Planning team urges the global One Health Community to be creative and find ways to help the world understand our urgent need for One Health.

Initiated in 2016 by the One Health Commission, the One Health Platform, and the One Health Initiative Team, International One Health Day is officially celebrated around the world every year on November 3. The One Health Platform closed its doors in 2021 so One Health Day was overseen in 2021 and 2022 by the One Health Commission and One Health Initiative Autonomous team.

The goal of One Health Day is to build the cultural will necessary for a sea change in how planetary health challenges are assessed and addressed and how professionals exchange information across disciplines. One Health Day brings global attention to the need for One Health collaborations and allows the world to ‘see them in action’.  The One Health Day campaign is designed to engage as many individuals as possible from as many arenas as possible in One Health education and awareness events and to generate an inspiring array of projects worldwide.

Events do not have to fall right on November 3 but can occur anytime during the calendar year.

[Note: Only Student Events wishing to compete for cash awards must fall within a set time window.

See Student Competition webpage.]
