"At the end of August 2012 ... the Usutu virus was found in one of
the blood samples from a donor in Hessen, Germany. The Usutu virus
is relatively new to the European Union as it is mostly found in
Africa. It is extremely rare that the Usutu virus has been found in
a blood sample, as infection is not common in Europe. These kinds
of exotic viruses are entering Europe more often given the effects
of climate change, which is making it a more attractive feeding and
breeding ground for these mosquitoes.
The warm summers are particularly important to mention, given
that climate change has been mentioned as one of the causes for the
increase in exotic mosquitoes in Europe. Research has been
done in the past to confirm that the advance of these exotic
mosquitoes in Europe is linked with the increase in temperature, as
well as the increase in international trade. An example shows
that stagnant water in truck tyres is an ideal environment for
mosquitoes to breed and they therefore travel with the truck.
Similarly, the mosquitoes travel via airplanes or trains as
This map gives an overview of some of the mosquitoes and
vector-borne viruses in the past five years in Europe.
