About Global Iodine Deficiency Disorders Prevention Day
Global Iodine Deficiency Disorders Prevention Day, also called World Iodine Deficiency Day, is observed annually on October 21 in public-health awareness material from the Government of India.
The day focuses on awareness of iodine deficiency disorders and the importance of adequate iodine nutrition at a population level.
Why Global Iodine Deficiency Disorders Prevention Day matters
Iodine is needed for thyroid hormone production and is especially important during growth and development.
Public-health guidance can explain prevention strategies, but an observance page should not diagnose deficiency or prescribe individual treatment or supplement doses.
