Define prevention of idd by Iodized Oil?

The other approach employed as a specific measure for women and children in hyper-endemic areas is injection of iodized oil. Intramuscular injection of iodized oil has been used for tackling goitre and cretinism in hyper-endemic areas in many countries of the world. The advantage of the injection procedure is that a single dose of 1 ml will provide protection for 3-5 years. Though, it has been found to be effective, the high cost and the difficulty in reaching all the victims of IDD make this approach less practicable. The use of disposable syringes, as a result of the risk of hepatitis-B and HIVAIDS, is now mandatory.
