Climate change is creating favorable conditions for the tiger mosquito to spread in Europe

An invasive species of mosquito has set up home in 13 countries in the EU, including France, Spain and Greece, with experts linking their presence to a rise in dengue fever in Europe. Climate change is creating favorable conditions for the tiger mosquito to spread, said the European Center for Disease Prevention and Control (ECDC). As far north as Paris, where the Olympic Games will take place at the end of July, authorities have been monitoring and trapping the insect. The ECDC has warned international travel will further increase the risk of more European outbreaks.

It has advised people to remove stagnant water from gardens or balconies, where mosquitoes can breed, and use repellent as well as screens on windows and doors. Mosquitoes have become a growing threat in Europe over the past two decades. The Asian tiger mosquito, aedes albopictus, which is thought to be the most invasive species of mosquito in the world, is now spreading across Europe from its southern European 'base camp'. It has become established in Austria, Bulgaria, Croatia, France, Germany, Greece, Hungary, Italy, Malta, Portugal, Romania, Slovenia and Spain, according to the ECDC. It has also been recorded in Belgium, Cyprus, Czechia, the Netherlands and Slovakia.

Tiger mosquitoes spread diseases such as dengue fever, chikungunya and Zika virus which, until recently, were typically only present in parts of Africa, Asia and the Americas. Another mosquito, aedes aegypti, which transmits yellow fever, as well as other diseases, has set up home in Cyprus. Experts say its potential for spreading to other parts of Europe is "concerning" given its preference for biting humans, and its ability to transmit disease.
