November 2 was the official day recognizing the importance of using iodized salt proclaimed by the government of Vietnam.

Deputy prime minister Truong Vinh Trong reminded that Vietnam had made a major effort to eliminate IDD between 2001 and 2005, reaching the 90% goal. In fact, 92.3% of Vietnamese households were using iodized salt in 2005. Recent surveys, however, he reported, have shown backsliding in a number of areas.
