Aims: To predict the risk of incursion of Crimean-Congo haemorrhagic fever virus (CCHFV) in livestock in Europe introduced through immature Hyalomma marginatum ticks on migratory birds under current conditions and in the decade 2075-2084 under a climate change scenario. Methods and Results: A spatial risk map of Europe comprising 14,282 grid cells (25 x 25 km), was constructed using three data sources: 1) ranges and abundances of four species of bird which migrate from sub-Saharan Africa to Europe each spring, namely Willow warbler (Phylloscopus trochilus), Northern wheatear (Oenanthe oenanthe), Tree pipit (Anthus trivialis) and Common quail (Coturnix coturnix); 2) UK Met Office HadRM3 spring temperatures for prediction of moulting success of immature H. marginatum ticks; and 3) livestock densities. On average, the number of grid cells in Europe predicted to have at least one CCHFV incursion in livestock in spring was 1.04 per year for the decade 2
