摘要

使用SEIR模型作为基本工具,尽可能准确地研究和分析了冠状病毒在印度的快速传播及其在不久的将来的行为。截至2020年10月10日,印度官方的covid-19感染和死亡病例数据被视为原始数据。通过在仿真模型中输入原始数据,对模型的各参数值进行优化。将各种参数定义为感染率、基本繁殖数、死亡率、恢复时间、暴露时间等参数,以优化最佳拟合模型。印度总人口被认为是13.6亿人。模拟结果显示,800天后,印度总人口的康复人数为2.8 × 108人,死亡人数为4.2 × 106人。在理想情况下,在大流行结束时,总死亡人数预计将达到106人左右,这是一个巨大的挑战。

The spreading of covid-19 in India and its impact: a mathematical analysis
The rapid spreading of the coronavirus in India and its behaviour for the near future has been studied and analysed as accurately as possible using the SEIR model as a fundamental tool. The official covid-19 data of infected and death cases in India upto 10th October, 2020 have been considered as raw data. The value of various parameters of the model is optimised by feeding the raw data in the simulation model. The various parameters are defined as infection rate, basic reproduction number, death rate, recovery time, exposure time, and other parameters to optimise the best fit model. The total population of India is considered 1.36 billion people. The simulation results that the number of recovered people will be 2.8 × 108 and number of deaths will be 4.2 × 106 after 800 days for the total population of India. In an ideal scenario, at the end of the pandemic total death count is expected to be of the order of 106 which is a big challenge.
