Mathematical Model for Coronavirus Disease 2019 (COVID-19) Containing Isolation Class.The deadly coronavirus continues to spread across the globe, and mathematical models can be used to show suspected, recovered, and deceased coronavirus patients, as well as how many people have been tested. 
Mathematical Model for Coronavirus Disease 2019 (COVID-19) Containing Isolation Class
For the numerical solution of the proposed model, the nonstandard finite difference (NSFD) scheme and Runge-Kutta fourth order method are used.
