(A) Incidence of UK EMRSA-15 every 4 weeks (red crosses) and cumulative cases (blue curve). (B) The raster plot for infections in 114 infected wards. Color indicates number of observed infections during 4-week periods. (C) Distributions of total patient numbers per ward (persons, upper panel), patient average length of stay (days, middle panel) and ward capacity (persons, lower panel) for infected and uninfected wards. (D) Overlaid degree distributions of 300 weekly aggregated contact networks. The solid blue line is the fitting to a Weibull distribution. Inset shows an illustration of the time-varying contact network. (E) A schematic of the model framework. The blue box defines the transmission process within hospitals, and imported infection and colonization from outside the study hospitals are quantified by two parameters and .
