The objective of this paper is to provide an insight on effect of stringency in Covid-19 spread in India especially in Chennai, a city were more lockdown, and restrictions was imposed to control the infection. Even though the restriction was imposed in the country by the end of March 2020, the growth reduction was seen in the mid of June as the awareness was increased. The average Covid-19 case growth was got reduce from 3.43 to 2.62% by July mid. To analysis the impact of stringency, a detailed analysis was done on Chennai city which was imposed with more repeated lockdowns to flatten the curve. We tried to fit a regression line with three difference scenario of data. The results show a promising -squared and value, with a right skewed distribution normal probability plot. The impact of lockdown in people's lives in different sectors were also discussed in this paper.
本文的目的是深入了解印度新冠疫情防控措施的严格程度对疫情传播的影响，特别是在钦奈市，该市实施了更多的封锁和限制措施以控制感染。尽管该国在2020年3月底就实施了限制措施，但随着人们意识的提高，6月中旬疫情增长出现了下降。到7月中旬，新冠病例的平均增长率从3.43%降至2.62%。为了分析防控措施的影响，对钦奈市进行了详细分析，该市实施了多次重复封锁以平缓疫情曲线。我们尝试用三种不同的数据情景拟合一条回归线。结果显示出了良好的决定系数和值，正态概率图呈右偏分布。本文还讨论了封锁对不同部门人们生活的影响。
