The tiger mosquito, capable of transmitting zika, dengue or chikungunya viruses, has settled permanently in more than half of the French departments, including Paris. Referring to the Ministry of Health, which published a map of the incidence of this double insect, the AFP reported.
Last year, the tiger mosquito (Aedes albopictus), which originated in Asia, permanently settled 51 of the 101 French departments. In 2017, scientists recorded its occurrence in only 42 administrative units. Apart from practically all of southern France, there is a mosquito, for example, in the northern department of Aisne, which borders Belgium.
The tiger mosquito can transmit viruses that cause fever, pain in the joints, head and muscles. In the European part of France he appeared for the first time in 2004 around Nice. Above all, global warming and intensified international transport contribute to the spread of tiger mosquitoes.
Every individual of this type of mosquito is not necessarily a carrier of any of these viruses, it only happens when it sucks the blood of an infected person, mostly outside of Europe.
For the first time, a mosquito, originally from Asia, was discovered in France in 2004 and settled in the Alpes-Maritimes department. As the French daily Le Monde writes, insects are basically "urban," and they like human populations. "When it appears in a municipality or in a department, it is basically impossible to get rid of it," the French authorities said.
The mosquito has also appeared on the French island of Reunion in the Indian Ocean for several years. The Ministry of Health recommends that people who travel to the island protect themselves. They are particularly encouraged to use repellents and wear clothing that covers larger parts of the body.
Since the first appearance of a tiger mosquito fifteen years ago, the authorities have reported 22 cases of dengue infection and 31 cases of chikungunya virus infection in France.
The tiger mosquito has rarely appeared in Břeclav region in South Moravia since 2012.
