论文摘要
本文我们有两个主要目标。首先，我们使用在网络上传播的疾病理论来研究COVID-19的流行病，这些流行病会引起预测，这些预测通常与通常使用的均匀混合方法有所不同。我们的第二个目的是研究社会剥夺的作用，再次以网络为基础，在这种流行病的传播中。我们选择加尔各答城市作为案例研究，但断言，如此获得的见解适用于人口稠密和社会不平等的各种城市环境。我们对热点的预测与当前被经验上的遏制区域的人非常吻合，并为识别潜在关注的领域提供了有用的指南。
We have two main aims in this paper. First we use theories of disease spreading on networks to look at the COVID-19 epidemic on the basis of individual contacts -- these give rise to predictions which are often rather different from the homogeneous mixing approaches usually used. Our second aim is to look at the role of social deprivation, again using networks as our basis, in the spread of this epidemic. We choose the city of Kolkata as a case study, but assert that the insights so obtained are applicable to a wide variety of urban environments which are densely populated and where social inequalities are rampant. Our predictions of hotspots are found to be in good agreement with those currently being identifed empirically as containment zones and provide a useful guide for identifying potential areas of concern.
