Simulate differential equation d t 2 d 2 y = 1 2 d t d y 5 y Simulate the SIR model dS / dt = ( I / N ) S dI / dt = ( I / N ) S I dR / dt = I S = Number Susceptible Individuals I - Number Infectious Individuals R = Number Recovered Individuals N = Total Population = Infection rate = Recovery Rate Compute using R0/7 as 7 days a week. R 0 2 , 5 . The population is 1 0 6 . The recovery rate is 1/7 indicating recovery using 7 days. Initial condition for S is 999833 . Initial condition for I is 166. Initial condition for R is 1..
