2019 edition of World Iodine Deficiency Day (WIDD)
The World Iodine Deficiency Day (WIDD) is observed every year on 21st of October to raise awareness of iodine deficiency and its devastating effects on brain development. Iodine is an essential micronutrient required for normal thyroid function, growth, and development. Its deficiency is a major cause of preventable mental retardation. In its most severe forms, Iodine Deficiency Disorders (IDDs) can lead to cretinism, stillbirth and miscarriage; even mild deficiency can cause a significant loss of learning ability.
