全球蚊媒淋巴丝虫病（LF）的目标是到2020年消除。为实现这一目标，在印度南部泰米尔纳德邦的一个干预和比较村庄，通过强化教育运动和教育前后调查，评估了作为大规模药物管理补充战略的社区病媒控制的范围。在干预前后对滋生地和蚊子密度的环境和昆虫学指标进行了检查。干预区居民对LF传播和控制知识的知晓率显著提高（P < 0.05）。干预前后干预村和对照村的相对变化也有显著性（z = > 1.96）。在干预后评估期间，使用了多种蚊虫控制和个人防护方法，从显著（P < 0.05）较高的平均得分中可以看出这一点。干预村养殖源数量显著下降（P < 0.05），相对变化显著（z = 4.32）。与基线相比，在干预区观察到每工时室内蚊子静止密度显著降低。减少87%蚊子密度的人均成本为0.32美元，表明以社区为基础的方法是有效的。讨论了这种策略在消除LF中的有用性。
Globally mosquito-borne lymphatic filariasis (LF) is targeted for elimination by 2020. Towards this goal, the scope of community-based vector control as a supplementary strategy to mass drug administration (MDA) was assessed through an intensive education campaign and evaluated using pre- and post-educational surveys in an intervention and comparison village in Tamil Nadu, South India. Environmental and entomological indicators for breeding sites and mosquito density were examined before and after the intervention. Significant (P < 0.05) increase in knowledge was observed in intervention area with regard to transmission and control of LF. Relative change between intervention and comparison villages before and after intervention was also significant (z = > 1.96). Multiple mosquito control and personal protection methods were in use during the post-intervention assessment and was evident from the significantly (P < 0.05) higher average score. Breeding sources declined significantly (P < 0.05) in the intervention village with a significant relative change (z = 4.32). Significant reduction in per man-hour indoor resting density of mosquitoes was observed in the intervention area compared to baseline. The per capita cost for reducing 87% of the mosquito density was $ 0.32 indicating the effectiveness of community-based approach. The usefulness of this strategy in the elimination of LF is discussed.
