Mini-leprosy elimination campaigns (Mini-LECs) were carried out over a period of 5 years (2000-2004) in Kaduna State, Nigeria. After careful preparation, the campaign team visited areas with a high suspicion of hidden cases in 12 selected Local Government Areas (LGAs). During the years of the 12 campaigns, 156 new cases of leprosy were detected against an expected number of 70 within the same LGAs. The results of the mini-LECs were analysed to find out if this cluster approach contributed significantly to the overall leprosy case finding and change in the proportion of the multi-bacillary (MB) forms of leprosy among new cases in the State. The analysis shows that, at LGA level, the number of cases detected during the year of mini-LEC is statistically higher then the expected number of cases. The MB proportion at LGA level did not change due to the mini-LEC exercises. Due to the limited number of exercises, the impact at state level is insignificant. However, the experience at LGA level suggests that with an increase in number of mini-LEC campaigns per state per annum an impact at the state indicators can be expected. In addition the campaigns should be repeated for further yield of new leprosy cases.
小型麻风病消除运动（Mini-LECs）于2000年至2004年期间在尼日利亚卡杜纳州开展，为期5年。经过精心筹备，运动团队走访了12个选定地方政府辖区（LGAs）中高度疑似存在隐匿病例的地区。在这12次运动开展的年份里，共检测出156例新麻风病病例，而同一地方政府辖区内预期病例数为70例。对小型麻风病消除运动的结果进行了分析，以确定这种聚类方法是否对该州总体麻风病病例发现以及新病例中多菌型（MB）麻风病形式的比例变化有显著贡献。分析表明，在地方政府辖区层面，小型麻风病消除运动当年检测出的病例数在统计学上高于预期病例数。地方政府辖区层面的多菌型比例并未因小型麻风病消除运动而改变。由于运动次数有限，在州层面的影响微不足道。然而，地方政府辖区层面的经验表明，每年每个州小型麻风病消除运动次数增加，有望对州指标产生影响。此外，应重复开展这些运动以进一步发现新的麻风病病例。
