Figure 6.8 Calculating R0A: hypothetical 12-area example. (A)
Base map with areas reference coded as a1…a12,
and associated space–time data matrix with reported cases for each area given in
cells. (B) Matrix rearranged to order leading edges, LE and (C) following or
trailing edges, FE. (D) Leading and following edges plotted as a
phase-transition diagram with susceptible (S), infected (I) and
recovered (R) integrals for areas.
