Fig. 3: Spatial immunization effect on SIR propagation.
From: Spatial immunization to abate disease spreading in transportation hubs
a Number of realizations with secondary infections in the airport facilities pR as a function of the number of immunized cells, normalized to the baseline case without spatial immunization pR(0) (each cell extension is 100 m2). b Boxplot of the distribution of contagions in the first 24 hours. Medians are shown as red lines, boxes represent the IQR, whiskers extend to 1.5 × IQR above and below the 75 and 25 percentile respectively. c New infections per time slot as a function of time and for different spatial immunization configurations. d Infections over the 7 day simulation period disaggregated in 5 categories: workers, passengers arriving in London, traveling to the UK destinations, to EU destinations and to other international destinations. For each category, Ni/N0 stands for the ratio between the number of infections with i cells immunized over the baseline without spatial immunization. e Relative composition of the infected population (see text). For each scenario we run n = 1000 simulations. See Methods and Table 1 for acronyms definitions.
