The CFR per closed reached 10.12% nearly to per total 9.82% in Dharavi on 31st July 2020. The CRR per total cases in Dharavi and Mumbai is 87.16 & 76.18% and per closed cases is 89.87 & 93.20% respectively in comparison to the CFR. The calculated CFR and CRR for both Dharavi and Mumbai suggest that the COVID-19 recovery rate is more than the fatality rate. The Dharavi people serve as an important role in controlling the pandemic by adopting 4-T model tracing, tracking, testing, and treating strategy.

印度孟买的达拉维区是亚洲最大的贫民窟之一，也是世界上人口最多的地区。COVID-19 爆发在 5 月达到顶峰，曲线在接下来的两个月内趋于平缓。本文重点介绍负责传播、预防和控制 COVID-19 在达拉维传播的因素。COVID-19 数据根据总病例恢复率 (CRR) 和病死率 (CFR) 进行解释，两者均已结案。2020 年 7 月 31 日，达拉维的每结案 CFR 几乎达到 9.82%。与 CFR 相比，达拉维和孟买的每结案 CRR 分别为 87.16% 和 76.18%，每结案 CFR 分别为 89.87% 和 93.20%。计算得出的达拉维和孟买的病死率和病死率表明，COVID-19 的康复率高于死亡率。达拉维人通过采用4-T模型追踪、跟踪、检测和治疗策略在控制大流行中发挥了重要作用。这篇文章有利于政府决策者和私人机构控制人口稠密地区的 COVID-19 大流行，也有利于死亡率高的国家。
