Also, I don't believe you need DynamicModule[] for that

comment Not seeing plot of solution returned by NDSolve
have you been able to run the NDSolve[]and/or the ParametricPlot[] outside the Manipulate (I mean as a stand-alone code)?

comment Extract the divergent/bounded part of a certain expression
I believe you're talking about a power Series. Otherwise you can always manipulate any expression to have as many "divergent" parts as you want cancelling out themselves when you add them up

@PabloGalindoSalgado I would just ensure that (without deaths) the total pop in each cell remains constant and proportionally distributed to the I[n] and S[n] coefficients. Although perhaps the non-neg limit ought to be enforced.

Like Sum[If[2 - n/2 >= 0, 0, c[n] r^(2 - n/2)] + d[n] r^(-n/2), {n, Infinity}]?
