To analyse the impact on of case finding of leprosy elimination campaigns (LECs), data on newly detected leprosy cases in a leprosy endemic area were collected before, during and after the year of LEC. The number of new leprosy cases detected during the year of LEC was significantly higher than previously. The number of newly detected cases after the year of LEC was similar to that of detected before the year of LEC in counties with persisting case finding activities. However, the number of newly detected cases after the year of LEC significantly decreased in counties without active case finding activities. The average distance from the homes of leprosy cases detected during LEC to the leprosy control unit at the count town was 62.8 km, which is farther than that of other leprosy cases detected before and after the year of LEC. The average time from disease onset to diagnosis of leprosy cases detected after the year of LEC shortened. The results also showed that carrying out LECs is unlikely to have a significant impact on the trend of case finding within a short time in local areas, but it may improve some indicators of leprosy patients and so promote leprosy control in local areas.
为分析麻风病消除运动（LECs）的病例发现对麻风病流行地区新发现麻风病病例数据的影响，在开展LECs的当年之前、期间和之后收集了该地区的数据。LECs当年新发现的麻风病病例数显著高于之前。在持续开展病例发现活动的县，LECs当年之后新发现的病例数与之前相似。然而，在没有积极开展病例发现活动的县，LECs当年之后新发现的病例数显著下降。LECs期间发现的麻风病病例住所到县城麻风病防治单位的平均距离为62.8公里，比LECs当年之前和之后发现的其他麻风病病例更远。LECs当年之后发现的麻风病病例从发病到诊断的平均时间缩短。结果还表明，开展LECs在短期内不太可能对当地病例发现趋势产生重大影响，但可能改善麻风病患者的一些指标，从而促进当地的麻风病防治工作。
