Efficient sentinel surveillance strategies for preventing epidemics on networks
(a) Examples of the two types of network. In the modular network p represents the probability that an edge will connect 2 nodes of the same colour. In the spatial network, edges can only connect nodes that are within distance r of each other e.g the edges of i are all in the green region. (b) Examples of sentinel placement strategies. (c) Strategies for networks with limited data. Examples of sentinel placement strategies with s = 3.
