Tigers mosquitoes trigger record wave:
This summer 2025, chikungunya is sadly talked about. Nevertheless, Never have indigenous cases reached such a level, in France as in Europe. However, Chikungunya. Furthermore, dengue and Western Nile virus, all diseases transmitted by mosquitoes, are now a real threat under our latitudeslatitudesdirect consequence of global warming.
French. Consequently, European health agencies alert to the rapid increase in infectious diseases transmitted by mosquitoesmosquitoes (Chikungunya, Dengue, Zika, Nil Western …) Alimentée par le climate changeclimate change. In addition, The European Center for preventionprevention. Moreover, disease control (ECDC) announced, in its press release, on August 20, that Europe had recorded this year a record number of cases related to viruses such as chikungunya and the nilthe nil tigers mosquitoes trigger record wave Western. However, Anrs-emerging infectious maladies (Anrs-MIE) evokes a real “invasion” of vectors mosquitoes. Similarly, an “early threat of arboviroses” (viral diseases caused by arbovirus). Similarly,
The chikungunya virus is transmitted to the human being by the mosquito bite of the genus Aedes. essentially the mosquito tigretigre (Aedes albopictusAedes albopictus), also vector of dengue viruses, yellow fever and zikazika.
The seasons of mosquitoes lie down. intensify – Tigers mosquitoes trigger record wave
In France, summer 2025 is distinguished by an unprecedented intensity of the Aboriginal cases of Chikungunya, that is to say having been contracted on French territory and not imported from regions where this infection rages.
As of August 19. Public Health France listed in its bulletin 27 households bringing together 154 cases, against 23 households and 115 cases the previous week. These figures far exceed those of previous tigers mosquitoes trigger record wave years, which did not count more than 30 cases in an entire summer!
They are located in the Provence-Alpes-Côte d’Azur, Corsica, Occitanie, Auvergne-Rhône-Alpes regions, already affected in previous years. But, for the first time, cases have been identified in Grand Est, Nouvelle-Aquitaine and Bourgogne-Franche Comté.
To these cases are added 932 cases imported from chikungunya from the 1isMay.
Everywhere in Europe, seasonsseasons transmission by mosquitoes lie down and gain in intensity. The ECDC attributes this phenomenon “to the rise in temperatures, to the longer summers, to winterswinters Softer and pluviometry changes. These conditions create an environment where mosquitoes thrive and transmit more viruses, ”summarizes the agency. For example, Aedes albopictus is now established in 16 European countries and 369 regions, against only 114 regions ten years ago.
More than ever prevention. and especially vaccine
As the landscape of tigers mosquitoes trigger record wave diseases transmitted by mosquitoes evolves, more people in Europe will be exposed to this risk in the future. For ECDC, prevention is therefore more important than ever, both by coordinated public health action and by personal protection measures.
ECDC therefore encourages people living in affected areas. visitors, especially the elderly, children and immunocompromised people, to protect themselves from mosquito bites using an insectifuge, by carrying long sleeves and pants, especiallydawndawn and at duskduskusing mosquito nets including bed and using the air conditioningair conditioning or fans. As well as avoiding any stagnant water.
In addition, new vaccinesvaccines have been developed against the Chikungunya virus.
A second chikungunya vaccine available since summer 2025
Arrived at the end of 2024 in France. Ixchiq was the first vaccine against chikungunya tigers mosquitoes trigger record wave (from 12 years old and up to 64 years old – ASM’s advice from 06/13/25). It’s a living vaccine attenuatedattenuated : it contains modified viruses so that they do not cause the disease. while stimulating the immune systemimmune system to protect the person vaccinated from infection.
The vaccinationvaccinationconsists of a single intramuscular injection into the deltoid muscle (shoulder). It targets people exposed to the virus. including travelers or inhabitants of risk areas located in Central Africa, India, Southeast Asia and Central and South America.
Since June 2025. a second vaccine (Vimkunya) has been available, intended to prevent chikungunya in people aged 12 and over, including those immunocompromised (European authorization of February 28, 2025). This time, it is a non-alive vaccine, produced from pseudo-viral particles (VLP, Virus-Like Particles). These particles reproduce the structure of tigers mosquitoes trigger record wave the virus without containing genetic materialgenetic materialwhich makes them non -infectious.
