History of Global Iodine Deficiency Disorders Prevention Day
Early Chinese medical texts, dating back to roughly 3600 B.C., were the first to document the reduction in goiter size following consumption of seaweed and burnt sea sponge, according to historical records. Even though iodine had not yet been found, these medicines remained successful, and their use persisted throughout the world, as attested in works by Hippocrates, Galen, and Roger in later centuries.
The discovery of iodine happened by chance during the first half of the nineteenth century. While extracting sodium salts for use in the production of gunpowder in 1811, Bernard Courtois, a French chemist, noticed an unusual purple vapor rising from seaweed ash treated with sulphuric acid. Gaspard Adolphe Chatin, a French chemist, was the first to publish the notion of population iodine deficit as a cause of endemic goiter, which was initially proposed in 1852. This was confirmed by Eugen Baumann, who in 1896 published a paper describing the discovery of iodine within the thyroid gland.
A goal to eliminate iodine deficiency by the year 2000 was set by world leaders during the 1990 World Summit for Children. As a result of this, countries such as India and China established their own National Days for the Prevention of Iodine Deficiency Disorders. Countries from all across the world have also thrown their support behind this initiative and found ways to ensure their citizens get enough iodine.
