论克山病消除的流行病学基础

On the epidemiological basis of elimination of Keshan disease

随着我国广大农村发展变化,昔日猖獗流行的克山病渐行渐远,全面消除目标正在接近实现。近年来考评结果反映,对消除工作的推进仍存在一定困难。通过阐释克山病发病与流行机制和病情消长调节因素,文中提出作为贫困导致的一种地方性生产生活方式疾病,经过长期粮食商品交换和脱贫扶助项目强化,克山病再次爆发的可能性极小,接下来应该修订消除标准,在防控策略上建议主要采用健康教育和提高社会经济水平来保持消除状态。

With the huge advances in mral China since 1980s, rampant Keshan disease (KD) has been fading away, and therefore we set an ultimate goal at overall elimination. In recent years, the evaluation results showed that there were still some obstacles in achieving this goal. By explaining the pathogenesis and epidemic mechanism of KD and the factors regulating the fluctuation of the disease, as a kind of local lifestyle disease induced by poverty, the author think, it will be of very low possibility in breaking out again thanks to the long-term exchange of cereal commodities and current poverty relief program. And the next move is to revise the existing criteria for KD elimination and to maintain the state of elimination primarily through health education and social economic improvement in all affected areas.
