摘要翻译：
阻止COVID感染需要社区集体行动，这在社会和经济多样化的环境中很难实现。利用印度的区级数据，我们检验了种姓和宗教分裂以及经济不平等对报告病例增长率的影响。研究结果表明种姓同质性的积极影响，而经济不平等和宗教同质性的影响有限。然而，随着全国封锁后的解锁程序，更高种姓同质性带来的好处被视为正在侵蚀。我们发现，即使在取消流动限制的情况下，通过种姓效应产生的社区凝聚力在农村地区仍相对占优势。我们的发现表明，规划者应该优先考虑在种姓不同的地区进行公共卫生干预，以弥补社区凝聚力的缺失。本研究的重要意义在于实证验证同质性与感染之间的因果关系，并为感染易发区的分区提供依据。

英文摘要：
  Arresting COVID infections requires community collective action that is difficult to achieve in a socially and economically diverse setting. Using district level data from India, we examine the effects of caste and religious fragmentation along with economic inequality on the growth rate of reported cases. The findings indicate positive effects of caste homogeneity while observing limited impact of economic inequality and religious homogeneity. However, the gains from higher caste homogeneity are seen to erode with the unlocking procedure after the nationwide lockdown. We find that community cohesion through caste effect is relatively dominant in rural areas even when mobility restrictions are withdrawn. Our findings indicate planners should prioritize public health interventions in caste-wise heterogeneous areas to compensate for the absence of community cohesion. The importance of our study lies in empirically validating the causal pathway between homogeneity and infection and providing a basis for zoning infection prone areas.
