Abstract:
Human assisted introductions mainly by global shipping of goods were shaping the global distribution of the Asian tiger mosquito (Aedes albopictus) in recent years. After having overcome oceanic barriers, future climate change may promote this introduced thermophilic species to extent its distribution within Europe. Of special interest are invasive vectors for vector-borne diseases, which may be introduced by infected travellers coming from endemic areas. As a consequence of increased international travel and intensified and frequent outbreaks around the world, a growing number of Dengue cases have been reported at higher latitudes. We identify emerging areas at risk for Dengue fever in Europe. Here, we model the evolving European climatic suitability for Aedes albopictus, a secondary Dengue vector. The model is based on published expert knowledge for input variables. We use the extrinsic incubation period of Dengue virus to detect potentially favourable regions, which will provide suitable climatic conditions for virus amplification. Finally, we superimpose suitable regions for vector, pathogen and possible introduction pathways. Implementing efficient biosecurity measures at European airports and harbours may limit accidental introductions of exotic disease vectors and pathogens. However, we see the importance of detecting preferred bioclimatic suitable habitats of disease vectors and pathogens. Then, specific monitoring systems can be concentrated in the respective regions.
