The Zika virus is spread by the yellow fever or dengue mosquito (aedes aegypti). Although the disease (Zika fever) is usually fairly mild, there are increasingly more indications that an infection during pregnancy can harm the unborn child.
Diseases that are naturally transmitted from warm-blooded animals to humans are called zoonoses. In Europe zoonoses originating from wildlife sources and transmitted by arthropods are considered to become increasingly important in the future. Climate and ecological changes may favour already existing arthropods to expand to other regions and thus new pathogens can be introduced in Europe.
