World Thyroid Day 2025

May 25 is World Thyroid Day (WTD). Established by the European Thyroid Association (ETA) in 2008, it has been commemorated annually since 2010, following the International Thyroid Congress in Paris, by the three sister associations: the American Thyroid Association (ATA), the Latin Thyroid Association (LATS), and the Asian Oceanic Thyroid Association (AOTA).
The ETA is a scientific organization, which aims to promote clinical and basic research and raise the standards of understanding and clinical practice in thyroid disease.
The Association was founded in 1965 and has met each year since then, with the exception of the years in which the International Thyroid Congress has been held. The Annual Scientific Meeting regularly attracts more than 350 abstracts and over 900 active participants. Membership of the Association consists of honorary, ordinary, junior, corresponding, emeritus and corporate members.
Currently the ETA has over 1.000 members. We invite you to join us!
