How could Zika enter Europe?

Researchers at the Institut Pasteur have assessed the transmission potential of four populations of Aedes mosquitoes in circulation on the island of Madeira and southern France with a view to examining various possible scenarios for the introduction of Zika virus to Europe. Their work suggests that the Aedes aegypti mosquito present in Madeira is more likely to promote local transmission of Zika virus than Aedes albopictus. Consequently, it appears that the risk of a Zika epidemic in continental Europe is still low.
