Risks of excess iodine intake in Ghana: current situation, challenges, and lessons for the future

In Ghana, iodine deficiency was first reported in 1994 among 33% of the population. A nationwide Universal Salt Iodization (USI) program plus other complementary interventions were subsequently implemented as a response.
