ZIKV importation in each susceptible spatial unit during 2015–2016: a Reported case count vs b median estimate of the total number of imported infections derived from the simulation model. Each country was treated as a single unit if the imported case count was reported at a country level (e.g. Australia, New Zealand), to facilitate comparison of the two maps. All donor spatial units were coloured in grey
