《全国学生常见病综合防治方案》包括蛔虫、沙眼、贫血、营养不良、肥胖、龋齿及视力低下六种常见病。在评估工作中,单一以某种常见病患病率作监测指标,由于六病患病率高低不一,难以对学校的防治总体状况作出整体评价。以这六病计算出的总发病率也不足以说明学校的防治好坏(六 The “National Comprehensive Prevention and Treatment Plan for Common Diseases among Students” includes six common diseases such as worms, trachoma, anemia, malnutrition, obesity, dental caries and low vision.
