The birthday of Sir Frederick Banting was designated as a United Nations World Health Day in late 2006. Since November 14, 2007, World Diabetes Day has been celebrated on Banting’s birthday in reflection of the work he, and Charles Best, did in regards to the discovery of insulin in 1921.
World Diabetes Day is represented by a blue circle logo. The blue circle, noted for its symbolism of positivity, life and health, is the global symbol of diabetes and signifies the unity of the global diabetes community in response to the diabetes pandemic. You can easily add one to your Twitter and Facebook profiles using the World Diabetes Day Twibbon.
Around the world, World Diabetes Day will be marked by more than 55 countries who will shine a light on diabetes awareness by flooding their landmarks with blue light.
