The virtual elimination of vitamin A deficiency and all its consequences is high on the political agenda as a solvable public health problem by the end of the decade. Five to six times more children in the developing world are likely to be subclinically than clinically deficient. Subclinical deficiency can be detected by newer methodological approaches. Subclinically deficient children are at increased risk of severe and fatal infections. The problem at a population level is avoidable by the appropriate selection and application of a mix of available interventions. Countries are challenged to assess, analyze and take actions to incorporate nutrition concerns into development planning to attain end-of-decade goals.
到本十年末，将维生素A缺乏症及其所有后果实际消除，作为一个可解决的公共卫生问题，已被列入政治议程的重要位置。发展中世界亚临床维生素A缺乏的儿童可能比临床缺乏的儿童多五到六倍。亚临床缺乏可以通过更新的方法检测出来。亚临床缺乏的儿童患严重和致命感染的风险增加。通过适当选择和应用一系列现有干预措施，在人群层面上这个问题是可以避免的。各国面临挑战，需要进行评估、分析并采取行动，将营养问题纳入发展规划，以实现本十年末的目标。
