Vitamin A deficiency (VAD) has been known to exist in Latin America and the Caribbean since the mid-1960s; however, except for pioneering work by the Institute of Nutrition of Central America and Panama/Pan American Health Organization on sugar fortification in Central America, there was little interest in controlling it because of the low frequency of clinical findings.

No obstante, si se exceptúan algunas iniciativas tempranas del Instituto de Nutrición de Centro América y Panamá, había escaso interés en controlarla debido a la detección infrecuente de signos clínicos.
