International Medicine 

and Disease Olympiad

the World Championship Medical and Disease knowledge and problem solving competition for High School Students

Welcome to Join IMDO Community Where Learning Knows No Bounds! 

The International Medicine and Disease Olympiad (IMDO) is the World Championship Medical and Disease knowledge/problem solving competition for High School students and is held annually online in July/August. 

The first IMDO was held in 2015 in San Diego, CA, and subsequently was moved online to lower the cost to compete for students throughout the world. The IMDO Foundation Board ensures that the competition is held each year and that each country selects their team in a fair and transparent process.

The IMDO aims to promote interest in the medical field by recognizing the strongest high school problem solvers interested in medicine. 

The IMDO aims to test both basic medical knowledge related to human medicine and disease, as well as problem solving abilities related to figuring out the best courses of actions given clues that a medical professional might encounter in their career.
