We present and analyze two simple NN-particle systems for the spread of an infection, respectively with binary and with multi-body interactions. We establish a convergence result, as NN\to\infty, to a set of kinetic equations, providing a mathematical justification of related numerical schemes. We analyze rigorously the time asymptotics of these equations, and compare the models numerically.
