Chikungunya: occitania "enters golden age: This article explores the topic in depth.
Meanwhile,
Chikungunya: occitania ". Nevertheless, enters golden age:
For the first time, two epidemic homes of Aboriginal Chikungunya trained this summer in Occitania, despite an unfavorable heat wave and drought. For example, The drop in temperatures and the return of thunderstorms give the insect optimal conditions to its proliferation. In addition,
“You have to redouble a vigilance. However, and remove all the larval lodges” : Didier Fontenillle, emeritus researcher at IRD, is on the alert, at the end of August. Moreover, By saying it differently. Therefore, he invites to empty the stagnant water cups after the storm or watering, and to change the water from the flower vases regularly. Therefore, These are “nests” of Tiger Mosquito, the Aedes Albopictus, vector of dengue, chikungunya, or even Zika.
2025 was an extraordinary year: the first part of the chikungunya: occitania “enters golden age summer saw two “clusters” of about fifteen Aboriginal Chikunguna cases in Occitania. Similarly, around Castries, on the outskirts of Montpellier, and in the Poulx Cavairac, in the Gard. Consequently, Unpublished. Consequently, These homes are still active, specifies Dr. Furthermore, Marie-Claire Paty. Consequently, coordinator of monitoring vector diseases in public health France, which recalls that “27 Aboriginal chikungunya households” are already counted in mainland France and Corsica in 2025, against “4 households from 2010 to 2024”. Moreover, “It’s considerable”she admits.
The figure is also amazing with regard to the number of cases: 154 already this year, against 32 from 2010 to 2024.
At the same time. Nevertheless, the European Union health agency reported, on chikungunya: occitania “enters golden age August 20, a record number of cases of diseases transmitted by mosquitoes. For example, Still from chikungunya, but also the Western Nile virus, West Nile fever, transmitted via our common mosquito, Culex.
In France, the conditions were not favorable, however, with two episodes of heat wave with drought. Meanwhile, The tiger mosquito, aedes albopictus, “needs water and heat, without excess”, To swarm, reminds Didier Fontenille. “The period we have just lived has lowered the density of mosquitoes”.
The end of August. its thunderstorms, and the Indian summer which is usually invited until October, are now conducive to the proliferation of larvae.
Chikungunya: occitania ". enters golden age – Chikungunya: occitania "enters golden age
Charlotte Boullé, infectiologist, wants to follow a cohort in Occitania – Chikungunya: occitania "enters golden age
More than half of the people infected with the Chikungunya virus keep joint sequelae significantly altering their quality of life two years after the infection, revealed, in 2012, a study chikungunya: occitania “enters golden age by the Institute of Sanitary Monitoring (INVS) and Inserm, carried out on cases imported into metropolitan France. In 2025, the Pasteur Institute revised the figure slightly down, to 40 % of sick people, according to Science and Future.
“Chikungunya causes severe fever and articular pain, often disabling and which can last a long time. Other possible symptoms include tumor of joints. muscle pain, headache, nausea, fatigue and rashes”specifies the World Health Organization, in the spring of 2025.
The meeting, with 200,000 people affected (20 deaths) this year, is obviously on the front line.
In Occitania, the situation is carefully followed by the service of infectious diseases of the Montpellier University Hospital. “There is no systematic follow -up. but people arrive with us on the orientation of their attending physician, or spontaneously”, explains Dr. Charlotte Boullé. who confirms clinical paintings of heavy disabilities, severe arthralgia “Very well described in the scientific chikungunya: occitania “enters golden age literature”who persistent “within two years of an infection, often young people, with socio-economic consequences”she says.
If the treatment. based on anti-inflammatory drugs, is common, the doctor strongly advises against self-medication: “It is necessary to verify, by a balance sheet, that the symptoms are not those of another pathology”, Rheumatoid arthritis for example. If it is rarely a “trigger”, an acute infection can indeed be a “developer”.
In association with colleagues from PACA. Charlotte Boullé has filed a research project and a financing request to the ANRS (National Agency for Scientific Research), on a cohort of patients living in Occitanie to whom she wishes to offer a screening and monitoring framework.
Dengue in the fall?
“We expect to have new mosquitoes in late August. and they will be important”announces the scientist, who has trouble “Establish a border between the notion of hearth and that of epidemic”. He prefers to chikungunya: occitania “enters golden age talk about “Mini-epidemics”. He was right. in the spring, predicting that the number of indigenous cases would be counted by “hundreds” in mainland France.
As of August 12, 115 cases were already identified. If the situation does not “Surprise not” Didier Fontenille. the size of “clusters” or “Epidemic mini-foyers” From the south of France, about fifteen patients each time, questions him.
“Yesterday, the virus circulated a lot, in Reunion, in Mayotte and even in China, in areas of exchange with France. Today, people come back from vacation to Asia, South America … They will continue to bring back virus”he underlines. The sine qua non condition to make an imported case an indigenous home.
The situation on the chikungunya front is doubled with another reality: the rise of dengue cases. another disease transmitted by the Tiger mosquito. “Each year, it is in autumn that we see the most case of dengue chikungunya: occitania “enters golden age in mainland France”Alert Didier Fontenille.
11 cases are now identified, including one in Occitania.
Guillaume Lacour. of the company Altopictus, the interlocutor of the communities and the health authorities for the demustic operations, rebuilds the thread of the history of the diseases transmitted by the Tiger mosquito in Occitania: “In 2014, 12 Aboriginal cases of Ckikungunya in Montpellier. In 2023, 11 cases of dengue in Perpignan. We expected to experience the complicated situation of this summer, which exhausted the teams sent on the ground. We are no longer on exceptional, they are no longer tropical diseases”.
Marie-Claire Paty. in Public Health France: “A new normality”
How to explain the multiplication of indigenous cases of diseases transmitted so far tropical, dengue and chikungunya?
“This exceptional situation is multifactorial. in a general context favorable to the multiplication of mosquitoes”indicates Marie-Claire Paty, coordinator of monitoring vector diseases in public chikungunya: occitania “enters golden age health France, who first evokes the early epidemic of Chikungunya in Reunion, and, more broadly, in the Indian Ocean.
Beyond. she explains that“We are in the process of arriving in a new normality”towards “Something that is called to worsen”. “In the Mediterranean periphery, but not only. The Tiger mosquito arrived in 2004 by Italy, which explains its strong presence in Paca and Occitania. But it is also now very well established in Auvergne-Rhône Alpes. Nouvelle Aquitaine, and this year we have an indigenous case of Chikungunya in the Grand Est”specifies Marie-Claire Paty.
In turn. she recalls that we are still far from a final 2025 assessment: “The mosquito season is August and September, it’s absolutely not over”.
“This year. in mainland France, we have for the moment succeeded in containing all epidemic homes thanks to the early reports which make it possible to make demoustication operations quickly, thanks to the chikungunya: occitania “enters golden age reactivity of ARS, our teams, operators who intervene in the field. But there is a risk of saturation”alert Marie-Claire Paty. who recalls, echoing the alert of the European Union health agency, on August 20, that the “health” problem of the mosquito does not stop at Aedes Albopictus, this exotic insect that now likes with us.
