International Medicine and Disease Olympiad (IMDO) 2026 Guide

Q: Can a student in Singapore register directly for IMDO 2026?
A: No. The organiser describes IMDO as invite-only. Its current rules name ChinaMDO, LitMO, UKMDO, and ThaiMDO for their respective countries, with USMDO used for all other countries. A Singapore student should therefore check the current USMDO route rather than look for open IMDO registration.

Quick facts
The organiser scheduled IMDO 2026 for 23 August, so the published event date has passed. Its results page says results are posted within one week of the event. No 2026 result listing was visible on that public page when checked on 25 August. Competitors must be selected to represent a country and satisfy the published age, identity, and education conditions.

Last reviewed: 25 August 2026. The official IMDO home, rules, resources, results, and partner pages were checked as a complete set. The result window remains open through about 30 August under the organiser's one-week statement.

What IMDO is

The International Medicine and Disease Olympiad is an international competition focused on knowledge and problem solving related to medicine and disease. The organiser says its content is set around what a student might know after the first year of a US medical school, with a minority of questions potentially going beyond that level.

This is not a general secondary-school science quiz. The stated knowledge level is substantially beyond a normal school syllabus, and the eligibility rule is based on age and college enrolment rather than the label "secondary student".

IMDO 2026 date and format

The official rules state that the 2026 competition was scheduled for:

• date: 23 August 2026;
• delivery: online;
• duration: three hours;
• question types: a mix of multiple-choice and free-response questions; and
• focus: knowledge and problem solving related to medicine and disease.

The public rules page does not currently state every operational detail a competitor may need. Selected students should obtain the current instructions for timing, identity checks, permitted aids, platform, and supervision from the organiser or qualifying body.

The scheduled date has passed. The public rules page still uses scheduling language, so this guide does not treat it as independent proof that every planned sitting was completed.

Eligibility

The current organiser rules require a competitor to:

• be selected to represent a country;
• be 20 or younger when IMDO is held, subject to the organiser's stated possible one-month exception requested by the partner organisation;
• be a citizen, permanent resident, or equivalent of the represented country; and
