I am not a biologist by profession, but I am attempting to implement a simple SIR model from the following paper. The paper assumes the following constants are known:

rc = growth rate of susceptible group S

k = carrying capacity of susceptible group in absence of infection

alpha = max value of per capita reduction rate of S due to I

a = half saturation constant

gamma = natural recovery rate from infection

delta = death rate of recovered population

I found some coronavirus data from the following source, and I plotted the Italy data in particular:

  • Can I calculate the constants above from this type of data?
  • Is it a good assumptions for these "variables" to be constant?

Here is my attempt of the model with the constants given in the paper

    $\begingroup$ I'm voting to close this question as off-topic because it appears to be a question about mathematical modeling rather than biology. $\endgroup$
