Visceral leishmaniasis (VL) is one of the world's worst parasitic killers, second only to Malaria, claiming thousands of lives every year. More than three fifths of the world's VL cases occur in the Indian state of Bihar alone. While some research has been conducted with emphasis on the effects of climatic variables on the VL incidence rate, rigorous analysis of the effects of socio-economic variables is still lacking. In this paper a regression model is developed that describes the relationship between VL incidence rate and a variety of socio-economic factors. It uses data from 2005 and explains 92% of the observed variance. In addition, a stepwise regression model is also used to identify the most important factors that facilitate the prevalence of the VL disease. A discussion on how to most effectively distribute Bihar's limited resources on various control measures to decrease the incidence of VL is also presented.
内脏利什曼病（VL）是世界上最严重的寄生虫杀手之一，仅次于疟疾，每年导致数千人死亡。世界上超过五分之三的内脏利什曼病病例仅发生在印度比哈尔邦。虽然已经进行了一些研究，重点是气候变量对内脏利什曼病发病率的影响，但仍然缺乏对社会经济变量影响的严格分析。本文开发了一个回归模型，描述了内脏利什曼病发病率与各种社会经济因素之间的关系。它使用了 2005 年的数据，并解释了 92%的观察到的方差。此外，还使用逐步回归模型来确定促进 VL 疾病流行的最重要因素。还讨论了如何最有效地在各种控制措施上分配比哈尔邦有限的资源，以降低 VL 的发病率。
