Procedure MakePathogens

	Input: population V, pathogen prevalences ${\left\{{\mathbb{P}}_k\right\}}_{k=1..p}$
	Output: {Ak}k=1..p
1	A1 = A2 = ... Ap = $\varnothing$
2	foreach k in 1... p do
3	foreach vi in V do
4	$t≔f_k^{\mathcal{B}}\left(v\right)$, identifying the pathogen-k class of vi in Domain$\left({\mathbb{P}}_k\right)$.
5	τ := pk;t the corresponding pathogen-k prevalence rate in Range$\left({\mathbb{P}}_k\right)$.
6	if Random(0, 1) < τ then
7	Ak := Ak ∪ {vi}
8	return {Ak}k=1..p
