COVID-19 SEIR Epidemic Model

This project is a part of my coursework, which consists of the generalized SEIR model, dataset and analysis code. Most of code in this project is based on Ref [1]. The SEIR model is proposed in Ref [2].

File Structure

data
 | - HuBei.csv filtered dataset
 | - 湖北省新冠疫情统计数据(原版).xlsx unfiltered dataset
SEIQRDP.m used to simulate the time histories of the infectious, recovered and dead cases (among others)
fit_SEIQRDP.m estimating the ten parameters used in SEIQRDP.m in the least square sense
HuBei.mlx HuBei province cure_and_dead.mlx how cure rate and dead rate is changing in epidemic development
protection_rate.mlx the importance of protection_rate quarantine_rate.mlx the importance of quarantine_rate

Example

Example 1

The example 1 is used to estimate parameters of SEIR model, and then fit real data, whose file is named HuBei.mlx

The results is following:curve

Example 2

The example 2 is used to show the changing of cure rate and dead rate in cure_and_dead.mlx

The results is following:curve

Example 3

The example 3 is used to show the importance of protection rate and quarantine rate in protection_rate.mlx and quarantine_rate.mlx

The results is following:curve curve
