Schematic diagram of the network model. At any time \(t\), nodes \(i\) and \(j\) are linked in three ways: nodes \(i\) and \(j\) are both in layer \(L1\) at the same time, both in layer \(L2\) at the same time, or one in layer \(L1\) and one in layer \(L2\). MPXV can be transmitted via the link if the infected individual in layer \(L2\) has effective contacts with the susceptible individual in layer \(L1\)
