Hello colleagues,

I would like to know whether the variable D of dead persons could be included in the model considered. Up till now the model considers the variables S - susceptible, I - infected and R - recovered. Where do the Dead persons D go.
Of course i such case the system will be of four differential equations.

Best regards

Vesela

Hello Heinz,

Here is an interactive version (made for my children last week...) :

Great many thanks:

o The SIR model is great and can be readily understood.

o Scilab is great: one line of code where big EXCEL sheet produced a
mess.

o Scilab friends and colleagues are great: instantaneous and real
help.

If the modelling is anywhere near to right, it will soon be over in
Austria (cyan circles are recorded infections). But this is likely
over-optimistic.....
