In visceral leishmaniasis (VL), phlebotomine vectors are the main target to reduce for control measures. An attempt has been taken to delineate the association between Phlebotomous argentipes and housing characteristics between two districts e.g. endemic and non-endemic.
A cross-sectional survey was conducted on 240 households for both the endemic (Vaishali district) and non-endemic (Lohardaga district) site. Logistic regression analysis was used to identify factors related to housing characteristics influencing suitable habitats for P. argentipes. Vector density estimated using a CDC light trap.
The proportion of P. argentipes in both endemic and non-endemic areas was significantly much higher (P < 0.001) when compared with the proportion of Sergentomiya and P. papatasi. The results of multilevel logistic regression analysis showed that mud plastered wall (P value = 0.001), mixed dwelling (P value = 0.002) and area (P value = 0.001) were strongly associated with the presence of vectors.
Result of the studied household characteristics provides an accurate, rapid assessment of house-level variation in risk. The results also have implications for maximizing surveillance efficacy of sandflies, which is likely to become increasingly important while formulating any control strategy.
在内脏利什曼病（VL）中，白蛉媒介是控制措施的主要靶向减少对象。已尝试描述中华白蛉与两个地区（即流行区和非流行区）房屋特征之间的关联。
对流行区（瓦伊沙利区）和非流行区（洛哈达加区）的240户家庭进行了横断面调查。采用逻辑回归分析来确定与影响中华白蛉适宜栖息地的房屋特征相关的因素。使用疾控中心诱蚊灯诱捕器估计媒介密度。
与赛氏白蛉和巴氏白蛉的比例相比，流行区和非流行区中华白蛉的比例均显著更高（P < 0.001）。多水平逻辑回归分析结果表明，泥墙（P值 = 0.001）、混合住宅（P值 = 0.002）和面积（P值 = 0.001）与媒介的存在密切相关。
所研究的家庭特征结果提供了对房屋层面风险变化的准确、快速评估。这些结果对于最大限度提高白蛉监测效果也具有重要意义，在制定任何控制策略时这可能会变得越来越重要。
