    New dengue fever case in France, victim had not travelled to risk area
    The case in Hautes-Pyrénées may have come from a tiger mosquito which had already bitten a person infected while travelling
    23 August 2022 14:57
    By Emma Morgan

    A new case of dengue fever has been detected in Hautes-Pyrénées (Occitanie), and the person in question had not travelled to a high-risk country.

    The infected person lives in a small village called Andrest, to the north of Tarbes, and mosquito eradication is currently being carried out in the area.

    Occitanie’s Agence régionale de santé has confirmed that the person had not recently travelled to a country where the virus is active.

    It added that the person’s condition is not causing concern among medical staff.

    The mayor of Andrest, Louis Dintrans, told France 3: “This year, we have been invaded by tiger mosquitoes. There are more than in previous years...

    A new case of autochthonous dengue declared in Haute-Garonne, we tell you how the disease arrived in Occitania
    Published on02/09/2022 at 08:58 • Updated02/09/2022 at 09:06
    Written by Stephanie Bousquet

    After two cases in the Hautes-Pyrénées, a new autochthonous case of dengue was confirmed in Haute-Garonne this Friday, September 2 by the Regional Health Agency (ARS) Occitanie following a biological diagnosis.

    A new case of dengue, in Haute-Garonne this time

    This person is domiciled at La Salvetat Saint Gilles, his state of health does not inspire concern. The symptoms of this disease are similar to those of the flu. This virus is transmitted by the tiger mosquito in countries known to be infected.

    Indigenous cases

    But this infected person has not recently traveled to one of these countries. Another must have contracted the disease after being bitten while traveling in a country where dengue is present. On returning to metropolitan France, this person was bitten by a healthy tiger mosquito. After a few days, this mosquito can transmit the virus to another person. This is called an Aboriginal case.

    Usually absent from mainland France, dengue fever is an infectious disease that must be declared. In short, each case reported, whether imported or indigenous, gives rise to a health investigation carried out by teams from ARS Occitanie and Public Health France, which is currently underway. It is supposed to guide the prevention and control operations to be implemented both with the patients concerned and in their immediate environment.

    A preventive mosquito control operation

    In addition, to limit the risk of transmission of this virus via tiger mosquitoes, preventive measures are being deployed by a mosquito control operator mandated by ARS Occitanie.

    This preventive mosquito control operation will take place in the next few days at the Salvetat Saint Gilles. The residents concerned were also contacted by investigators from the ARS and Public Health France for a door-to-door health investigation.

    These local residents have received in their own hands or in their letterboxes, a health information note on the tiger mosquito and dengue fever, which provides them with all the details. Additional information on the course of interventions and treatments is accessible to everyone on the ARS Occitanie website.

    Any resident of the area who presents clinical signs must quickly consult

    In addition, all the inhabitants of this sector who would present clinical signs suggestive of a dengue fever infection are called upon to consult their doctor as soon as possible.

    These symptoms are a high fever of sudden onset beyond 38.5 degrees associated with at least one of these symptoms: headaches, muscle, joint or lumbar pain, all in the absence of cough, runny nose or breathing difficulties.

        Tiger mosquito: update on dengue fever cases in Occitania
        Published on09/07/2022 at 5:22 p.m.
        Written by Benoit Roux.

        Occitania has become the 2nd most colonized region in France by mosquitoes (after PACA). Beyond the not very pleasant itching, the presence of the tiger mosquito on the territory is synonymous with viral diseases: chikungunya, zika and dengue fever. For the time being, only 36 cases have been identified in 2022 in Occitania.

        Back to school is often synonymous with returning from travel and the viruses that we bring back in our suitcases. Talking about dengue fever in the West Indies or South America is altogether banal. It is less common in France where the ARS educate doctors and populations to avoid any epidemic.

        36 cases in Occitania

        Usually, health authorities identify around a hundred cases in Occitania (2019-2020). Obviously, this figure dropped sharply during the coronavirus pandemic when travel was very rare. The tiger mosquito which appeared barely 20 years ago in France (2004) is placed under surveillance in mainland France from May 1 to November 30.

        According to the ARS of Occitanie, in 2021 " 1964 municipalities out of the 4454 municipalities of the region (44%) are colonized, which represents 88% of the regional population, i.e. nearly 5.5 million inhabitants. "

        This year, it is the department of Haute-Garonne which has the most reports. There are 2 scenarios:

        imported cases (brought back from a trip): 30 in Occitania
        indigenous cases ( person having contracted the disease without having traveled to the contaminated area): 6 in Occitanie

        " For us , declares Isabelle Moussion, coordinating engineer for vector control at the ARS in Occitanie, imported cases are not trivial enough. We have raised the awareness of attending physicians, carried out prevention campaigns to identify cases of dengue and treat them quickly. Contaminated travelers must remain vigilant for 7 days after diagnosis and continue to use repellents to break the chain of transmission. It is more complicated for indigenous cases. Because there, we do not know the number of infected people, nor the exact area of ​​distribution.

        Doctors have a harder time diagnosing dengue for someone who hasn't traveled. As with the coronavirus, there may be asymptomatic people, carriers of the disease without declared signs.

        Here is the departmental breakdown of the 6 indigenous cases in Occitania:

        1 in the Pyrénées-Orientales
        3 in the Hautes-Pyrenees
        2 in Haute-Garonne (specifically in Toulouse, declared very recently)

        The mosquito has a radius of action of only 150m and when there is contamination, the ARS considers that the outbreak is extinguished 45 days after the beginning of the stay of the contaminated person....

            Dengue fever in metropolitan France: indigenous cases on the rise

            47 autochthonous cases of dengue fever divided into 5 outbreaks have been recorded in Metropolitan France since July 2022, as part of the seasonal enhanced surveillance of chikungunya, dengue fever and Zika in the metropolitan departments. The fight against disease-carrying mosquitoes is essential to prevent the occurrence of new outbreaks.

            Posted on September 20, 2022

            Dengue fever is an infectious disease caused by an arbovirus: the dengue virus. This virus is transmitted by mosquitoes of the genus Aedes: Aedes aegypti and Aedes albopictus (the latter is also called tiger mosquito). From May 1 to November 30 of each year, Public Health France coordinates the seasonal enhanced surveillance of chikungunya, dengue fever and Zika in the metropolitan departments, in conjunction with the Regional Health Agencies (ARS) concerned.
            In mainland France, surveillance of dengue (as well as chikungunya and Zika ) is based on mandatory reporting with reporting of any biologically documented case.


            Data as of September 20, 2022
            • Santé publique France has detected 5 episodes of autochthonous transmission of dengue fever. As of September 20, 2022, they total 47 cases, which is the maximum detected in mainland France. Previously the maximum had been 14 cases of autochthonous dengue fever in 2020.
            • The size of the outbreaks is larger than previously, in particular the outbreak of St-Jeannet-Gattières-La Gaude in the Alpes-Maritimes with 29 cases to which are added 2 cases identified in the commune of Saint Laurent du Var. Dengue transmission episodes had so far remained very limited, sometimes limited to 1 autochthonous case. The most important episode concerned 8 people in Nîmes in 2015.
            • Beyond the number of cases, this year 2022 is characterized by the extension of the risk on the metropolitan territory with the occurrence of outbreaks in departments hitherto spared: the eastern Pyrenees, the Hautes Pyrénées and the Haute Garonne. Previously the cases had mainly occurred in the Var, the Alpes Maritimes, the Hérault, the Gard.

            What are the symptoms ?

            The symptoms of dengue fever are most often flu-like (fever, headache, body aches) possibly associated with a rash and appear within 3 to 14 days (4 to 7 days on average) following the bite by a infected mosquito. Dengue affects infants, young children and adults alike. Most often benign although the symptoms are sometimes very marked, dengue can however be complicated by visceral failures and hemorrhagic forms justifying hospitalization in intensive care.


            How is this increase explained?

            This development is linked to several factors, in particular:
            • the extension over the territory and the high densities of the mosquito vector Aedes albopictus ;
            • the resumption of travel and the return of travelers from endemic areas;
            • climatic conditions favorable to the multiplication of mosquitoes with heat and rain.
            Since 2010, we have witnessed the repetition of these episodes which have gradually become habitual each year. It can be dengue but also chikungunya, zika, which are transmitted by the Aedes albopictus mosquito .
            In the future, these episodes are bound to recur, increase in size and occur in new departments. The development of an epidemic is not excluded, as was the case in Italy in 2007 and 2017 with epidemics of 300 to 400 cases of chikungunya. The emergence of "new" viruses could also appear, as was recently the case with the chikungunya and zika viruses in 2006 and 2016.


            What prevention should be put in place?

            Dengue prevention is based on individual and collective actions:
            • Fight against breeding sites at home and in public spaces: store everything that can contain water (buckets, watering cans) sheltered from the rain; hermetically tarpaulin or cover with a mosquito net the water reserves (barrel, canister, untreated swimming pool); regularly empty the saucers of the flower pots; ensure that the gutters run smoothly; pick up green waste that can become resting places for adult mosquitoes.
            • Protect yourself with protective clothing, mosquito nets and repellents (sprays or creams, coils, electric diffusers), especially when traveling in endemic areas and on returning from travel to avoid infecting mosquitoes. Protection is particularly necessary during the day, the Aedes vector mosquitoes biting especially during the day, mainly outside houses, with a greater activity in the early morning and at the end of the day.
            • Implementation of mosquito control by the ARS as soon as an imported case or a local case is reported (dengue fever is a notifiable disease). These interventions make it possible to eliminate potentially infected adult mosquitoes and eliminate breeding sites to limit the proliferation of mosquitoes in the sector concerned and break the chains of transmission of the virus. Many research projects aim to develop and implement new techniques that do not rely on mosquito control based on chemical insecticides.
            • Develop vaccines : a first vaccine against dengue fever has been put on the market with limits of use, in particular, it is not recommended for people living in mainland France. Others will soon follow. There is no vaccine against chikungunya and Zika yet.
            What is the link with climate change?

            Infections transmitted by mosquitoes are among the infectious diseases most linked to climate change and especially to global changes: warming, drought, heavy rains and floods favor the proliferation of mosquitoes. Globalization with the importance of commercial and human exchanges across the globe, deforestation and urbanization are factors that strongly contribute to the multiplication of diseases transmitted by mosquitoes.
            Faced with these combined factors, a global, multidisciplinary response involving all societies and populations is needed. This is the basis of the “one health” concept.

                    Dengue fever: a first autochthonous case of arbovirus detected in New Aquitaine

                    The Regional Health Agency (ARS) Nouvelle-Aquitaine announced on Thursday that it had spotted in Biscarosse (Landes) a first case of autochthonous arbovirosis, that is to say a disease transmitted by the tiger mosquito to a person who did not have traveled to high-risk areas. Analyzes must determine if it is dengue fever, Zika or West-Nile. Seven areas where the patient went, including three in Gironde (Bordeaux, Le Bouscat and Le Pian-Médoc), will be the target of mosquito repellent treatments.

                    A "suspicious case" was reported on October 7 to the ARS, confirmed on October 18: it would be the first patient from New Aquitaine to have contracted an arbovirosis in the region, the agency announced in a press release this Thursday, October 20.

                    “Usually the ARS is called upon to intervene in declared cases of arbovirosis (such as dengue, etc.) by people who have traveled outside mainland France, in risk areas where these diseases are endemic. In the present case, the infected person has not left mainland France [nor] recently traveled to a risk area (15 days prior to the onset of symptoms)”....

                      Surveillance of arboviruses in metropolitan France: sharp increase in autochthonous dengue cases in 2022


                      Posted on July 11, 2023
                      Updated on July 10, 2023


                      The Aedes albopictus mosquito, implanted in metropolitan France since 2004, continues to increase its range. To limit the risk of autochthonous transmission of the arboviruses that it can transmit (dengue, chikungunya and Zika), surveillance of cases, both imported and autochthonous, has been in place since 2006. Surveillance is based on the mandatory notification of biologically documented cases. It is reinforced between May and November, in particular by the analysis of laboratory data making it possible to identify undeclared cases and guides the application of control measures (vector control). In 2022, 378 imported cases of dengue fever, 23 of chikungunya and six of Zika were notified in metropolitan France. Nine episodes of autochthonous dengue transmission totaling 66 cases have been documented: five episodes in Occitania (12 cases), three in Provence-Alpes-Côte d'Azur (52 cases) and one in Corsica (two cases). Six of these episodes occurred in departments where no autochthonous case had been previously reported. The occurrence of autochthonous dengue cases is now an expected phenomenon in the south of France, but the situation was exceptional in 2022: an increase in the number of episodes, their intensity and the geographical areas concerned. The multiplication of episodes and the extension of their geographical distribution could jeopardize the viability of the system. Maintaining the ability to limit autochthonous transmission of arboviruses requires the sustained involvement of surveillance, prevention and control actors,
