    Paris: three cases of dengue fever identified in the 15th arrondissement, a mosquito control operation to come

    Three cases – a couple and their child returning from Martinique, according to our information – were detected in the area of ​​rue Dombasle. A treatment operation is organized during the night from this Friday to this Saturday to prevent the spread of the virus. “A very localized operation,” reassures Philippe Goujon, mayor of the 15th century.

    September 14 , 2023 at 8:28 p.m. , modified September 15, 2023 at 7:00 a.m.

    If you live in the Dombasle sector, in the 15th arrondissement of Paris, you will need to make sure to close your windows tightly next night. The instruction is formulated by the regional health agency (ARS) and the district town hall after the detection of three cases of dengue in the neighborhood. An investigation orchestrated by the health authority would have established the presence of adult tiger mosquitoes, vectors of the virus, in the area concerned.

    The convergence of these three cases and the presence of insects therefore obliges the authorities to treat a precise perimeter of this sector. The procedure requires that an “anti-vector control operation” takes place within a radius of 150 m around the home of people contaminated by dengue fever, an infection which occurs largely in tropical areas. According to our information, the infected people are a couple and their child, returning from Martinique.

    This operation is planned for the night of this Friday to Saturday, from 2 a.m. It should last a couple of hours. It will be carried out by the ARS and the regional mosquito control agency in order to reduce the health risk. The authorities will use approved insecticide products which will be sprayed into the air.

    Some instructions to follow

    “This operation is very localized,” reassures Philippe Goujon, mayor (LR) of the 15th arrondissement. Residents will not notice anything. The system is very complete to eradicate the insect, we have the experience of that which was carried out in the 13th century, a few days ago. This Thursday evening, the councilor sent a letter by post to 1,500 addresses in this small area straddling rue de la Convention and rue de Vaugirard to communicate the few instructions to be respected.

    “We ask them to leave their windows closed, residents will have to confine their pets and put away objects and anything lying around on the balconies,” specifies the elected official. The police headquarters services will ensure that traffic is prohibited for pedestrians and motorists in the few streets concerned for the duration of the operation.

    Insecticide in school grounds

    In this sector there are restaurants which will have to close before 2 a.m. Schools also in which the health authorities, on board a van, should stop, particularly in planted courtyards, in order to spray the insecticide. “Since the beginning of the 2000s, the tiger mosquito has been in France, moving northwards as a result of global warming,” analyzes Philippe Goujon.

    Paris: after three cases of dengue, a district of the 15th arrondissement was cleared of mosquitoes last night

    Three cases of dengue had been reported near rue Dombasle (15th). A mosquito control operation targeting tiger mosquitoes took place during the night from Friday to Saturday. Agents were able to manually process all affected private yards.

    After the census of three cases of dengue fever within the same family, an ARS investigation was able to show that tiger mosquitoes, responsible for the transmission of the disease, were present in the area of ​​rue Dombasle (15th century ) . ). A mosquito control operation therefore took place during the night from Friday to Saturday in an area including part of Dombasle, Olivier de Serre, Vaugirard and Convention streets.

    “Five larval samples were taken in breeding sites containing water and the species Aedes albopictus ( Editor's note: the tiger mosquito ) was recorded at a convent on rue Dombasle and a medical-educational institute on rue Olivier of Serres. At the adult stage, two individuals were noticed on rue Vaugirard in the courtyard of a hotel,” specified the regional mosquito control agency.

    The operation took place at night, between 2 a.m. and 4 a.m. It started with the treatment of the interior courtyards, then the treatment with a pick-up on Rue de la Convention with the assistance of the police who closed access to the street from 3:30 a.m. The street and accesses were reopened around 5 a.m., approximately 1 hour after the end of the treatment.

    Already operations this summer in the 13th and in Hauts-de-Seine

    The agents were able to access private sites including the interior courtyard of the convent, the courtyard of the medical-educational institute, the interior courtyards of the comprehensive school, the exterior courtyards of the nursery school, and rue Lhuilier. All of these property yards have been manually treated in a pedestrian manner with targeted application on the vegetation. Previously, residents had been asked to leave their windows closed, to confine domestic animals and to put away objects and anything lying around on the balconies.

    “The whole treatment went very well. Officers were able to access all private and public yards and spray the insecticide. Whether those of the schools or the convent and the buildings which have a green courtyard, all the doors have been opened. A beehive, installed on rue Lhuillier, was even preserved in the operation,” notes Philippe Goujon, the mayor (LR) of the 15th century, welcoming the cooperation of local residents.

    A mosquito control operation after cases of dengue in Bourg-lès-Valence

    Bourg-lès-Valence
    From Florence Beaudet
    Tuesday October 3, 2023 at 4:02
    By France Bleu Drôme Ardèche

    A mosquito control operation was carried out on the night of Monday October 2 to Tuesday October 3 in a district of Bourg-lès-Valence for the two indigenous cases of dengue fever. A major operation.


    This has not happened since 2019 in the region. And this is a first in Drôme-Ardèche . Never before has there been a case of autochthonous dengue fever . The analyzes confirmed it: two people were indeed infected even though they had not traveled to areas affected by the disease. It was another person who was contaminated. She was then bitten by a tiger mosquito in Bourg-lès-Valence, a mosquito which then spread dengue fever.

    Eliminate all adult mosquitoes

    Hence the major mosquito control operation carried out in the district concerned, to eradicate all adult mosquitoes within a radius of 200 meters, or double their maximum flight distance. It was not a preventive operation like in Cornas in Ardèche at the beginning of September but rather a curative operation. Nine agents from the Interdepartmental Agreement for Mosquito Control sprayed insecticide at the maximum authorized dose, as close as possible to homes and on roads.

    This type of treatment is obviously not neutral. Residents were asked to sleep with their windows closed and to bring their children's toys inside. They are prohibited from eating fruits and vegetables from their garden for 48 hours. It now remains to identify the original case. A third suspected case is being analyzed and could be the person who brought dengue fever into the neighborhood.

    Une opération de démoustication a été menée dans la nuit de lundi 2 au mardi 3 octobre dans un quartier de Bourg-lès-Valence pour les deux cas de dengue autochtones. Une opération d'envergure.

    Indigenous cases of dengue fever in Bourg-lès-Valence (Drôme): situation update

    Health alert

    October 2, 2023




    The ARS Auvergne-Rhône-Alpes has received reports of 2 cases of indigenous dengue fever in Bourg-lès-Valence in Drôme.
    Find all the information on this situation and the actions implemented by the ARS and its partners.



    Context

    On September 27, the ARS received a report concerning the suspicion of 2 cases of indigenous dengue fever.

    A third suspected case was identified following the investigation carried out by the Interdepartmental Mosquito Control Agreement on September 29.

    The National Arbovirus Reference Center (CNR) confirmed the results of the first 2 cases. The ARS is awaiting results for the 3rd suspected case.

    These are the first indigenous cases of dengue fever identified this year in Auvergne-Rhône-Alpes.

    The ARS and its partners are mobilized to prevent tiger mosquitoes present in the neighborhood from transmitting the disease to other people.
    As a reminder, dengue is a viral infection that usually occurs in tropical areas.
    1. Most of the time, dengue fever reported in mainland France concerns people who have been contaminated during a stay in a tropical zone. If people come back infected, they are imported cases .
    2. The tiger mosquito present in our territory can become infested by biting a person who has become infected in a tropical zone and, by biting them, contaminate a person who has not traveled. This is then an indigenous case .
    Dengue symptoms appear on average 4 to 7 days after the infective bite.
    Health monitoring and actions implemented

    Remove mosquitoes from the area

    An entomological investigation was carried out locally on September 29: it confirmed the presence of tiger mosquitoes in the area where the infected people reside.

    A mosquito control operation is scheduled for Tuesday October 3 (between 2 a.m. and 5 a.m.) to limit the risks of transmission.

    Residents of the area concerned were informed by a flyer left in their mailbox or posted (collective housing).

    These two actions are carried out by the Interdepartmental Mosquito Control Agreement (EID) , an operator mandated by the ARS in vector control.

    For more information on mosquito control operations (procedure, sector, etc.), consult our dedicated page .


    Check if other people have been infected

    A door-to-door epidemiological survey will also be conducted on Wednesday October 4 and Thursday October 5 among residents of the area concerned by agents of the ARS and Public Health France.

    The objective is to ensure that people living in the area have not been contaminated by a tiger mosquito bite, to make them aware of the symptoms of dengue fever and to tell them what to do in the event of symptoms.

    All residents of the area concerned are informed.

    Furthermore, hospitals and health professionals (doctors, pharmacists and medical analysis laboratories) in the Bourg-lès-Valence sector have been informed of the situation.
    As a reminder, dengue is anotifiable disease: health professionals must inform the ARS in the event of a diagnosis of dengue.

    Recommendations to the population

    Monitor your health

    People returning from travel in tropical areas must be particularly vigilant and:
    1. avoid being bitten by tiger mosquitoes when they return
    2. Seek medical attention immediately if symptoms appear.
    People living in an area where tiger mosquitoes are present should also remain attentive and consult a doctor if in doubt.
    The symptoms suggestive of dengue fever are, in the absence of another established diagnosis: the sudden onset of high fever (>38.5°C), associated with at least one other clinical sign such as:
    1. headaches,
    2. muscle, joint or lower back pain,
    3. Rashes,
    4. in the absence of other infectious signs: respiratory signs, infected wounds, etc.
    Limit the proliferation of tiger mosquitoes

    The best way to avoid tiger mosquito bites is to prevent them from taking up residence in your home!

        This is the first case of indigenous dengue fever in the region. A first mosquito control campaign was held during the night from Sunday to Monday. The second will take place during the night of next Friday.

        A first indigenous case of dengue fever in Île-de-France was discovered in Limeil-Brévannes (Val-de-Marne) after a report on Wednesday October 11. Biological analyses, carried out by the Regional Health Agency (ARS) and Public Health France teams, confirmed the diagnosis.

        'A case is defined as indigenous when the person contracts the disease without having traveled to an endemic area in the 15 days preceding the appearance of symptoms', specifies the ARS in its press release.​

        C'est le premier cas de dengue autochtone dans la région. Une première campagne de démoustication s'est tenue dans la nuit de dimanche à lundi. La seconde interviendra dans la nuit de vendredi prochain.

          Vector control: the ARS confirms a first indigenous case of dengue in Île-de-France and initiates two mosquito control actions in Limeil-Brévannes (94)

          Press release
          October 17, 2023




          The ARS Île-de-France received on October 11, 2023 the report of a case of dengue fever concerning a person residing in Limeil-Brévannes (94). This case was confirmed by biological analyses. The investigation carried out by the Agency's services, with the Public Health France teams, made it possible to identify this case as the first indigenous case in Île-de-France.

          If indigenous cases have already been identified in mainland France, this is the first case in Île-de-France*. A case is defined as indigenous when the person contracts the disease without having traveled to an endemic area in the 15 days preceding the appearance of symptoms. In this context, the ARS Île-de-France wanted to deploy the reinforced anti-vector control measures planned for this type of case.

          Two successive mosquito control campaigns, the objective of which is to reduce the risk of spreading dengue fever, have therefore been planned in two localized areas of Limeil-Brévannes: the first took place on the night of Sunday October 15 to Monday October 16 , the second is planned for the night of Friday October 20 to Saturday October 21 if weather conditions permit, and will be postponed otherwise. These mosquito control operations will be coupled with a field survey including door-to-door visits to local residents to detect other potential cases and relay prevention messages.

          Strengthening vector control measures involves several actions:

          1 - repeat the adulticidal mosquito control treatment once (depending on weather conditions);
          2 - actively search for other cases of dengue, within a radius of 150 meters around the initial case, by encouraging people to be screened via biological sampling in the event of unexplained symptoms suggestive of dengue (high fever with sudden onset , muscle or joint pain, eye pain, fatigue, headache). Specific information will be provided to the local residents concerned;
          3 – protect yourself from bites (wearing loose clothing, mosquito repellent, etc.), particularly if symptoms occur;
          4 - inform health professionals and hospitals of the occurrence of a confirmed indigenous case of dengue fever, so that they are vigilant in their diagnosis when faced with symptoms suggestive of this disease and relay prevention messages;
          5 – act to limit the development of mosquitoes around your home (be vigilant and store everything that may contain water (buckets, watering cans) away from the rain), cover the reserves tightly or cover them with a mosquito net water (barrel, can, swimming pool), clean the gutters regularly);

          Two targeted mosquito control operations planned in Limeil-Brévannes

          These operations planned in Limeil-Brévannes, like the previous ones, aim to reduce the risk of spreading dengue fever, an infectious disease some of whose complications can be severe. They respect the same conditions as those carried out in recent weeks in Île-de-France. At the request of the ARS Île-de-France, the Regional Mosquito Control Agency (ARD), a private operator specializing in the detection and elimination of mosquitoes in Île-de-France, carried out an entomological investigation and We have already implemented measures to reduce breeding sites and raise awareness among the population in this case. The ARD proposed an intervention using an insecticide-based treatment targeting the resting places of the tiger mosquito (bushes, groves, foliage, etc.) within a 150 meter radius around the home of the patient concerned.

          This mosquito control operation is launched by the ARS Île-de-France by closely involving local stakeholders (city services, prefecture). Precise information is systematically provided ahead of these operations to residents of the area concerned who are invited to bring their outdoor plants in, to close their windows securely, and to keep their pets indoors. The national police and municipal police will take part in this operation to enable it to run smoothly by prohibiting access to pedestrians and traffic on public roads during the intervention and 1 hour afterwards.

          Actions carried out by the Agency in 2023 as part of vector control in Île-de-France

          In 2023, the ARS Île-de-France has authorized around twenty mosquito control operations in the Ile-de-France territory. These operations are carried out after the confirmation of a case of dengue in these localities. They are not intended to eliminate all traces of the tiger mosquito but to reduce the risk of spreading dengue fever, an infectious disease some of whose complications can be severe.

          Finally, the ARS Île-de-France will shortly take stock of the fight against vectors and cases of arboviruses in the Ile-de-France territory during the year 2023.

          3. Preventing proliferation is everyone’s business: all the information here

          * A possible indigenous case was reported in Nandy (77) in September 2023 , the latter was finally considered as an imported case due to a recent trip by the person concerned to an endemic area.

            DENGUE: 36 INDIGENOUS CASES DETECTED IN MAINLAND FRANCE SINCE THE START OF SURVEILLANCE

            Gillet Glenn with AFP
            THE10/24/2023 at 12:41


            Santé Publique France announced this Tuesday that 36 indigenous cases of dengue fever were detected in mainland France between May 1 and October 20.
            36 indigenous cases of dengue fever , this infectious disease transmitted by mosquitoes, were detected in mainland France between the start of the surveillance period, May 1 and October 20, Public Health France indicated on Tuesday October 24 .

            In its regular update on the data on the main diseases transmitted by mosquitoes and present in France (chikungunya, dengue and zika), the health agency specifies that the indigenous contaminations took place in Paca (two outbreaks and one isolated case for 14 cases in total), in Occitanie (two outbreaks for 19 cases), Auvergne-Rhône-Alpes (one outbreak of two cases) and, for the first time, in Île-de-France (one case).

            Increase over 20 years

            An “indigenous case” means that the person has not recently traveled to regions of the world, such as the Antilles, where this virus, transmitted from person to person by tiger mosquitoes, widely circulates.

            People suffering from indigenous cases were therefore probably infected in mainland France after being bitten by one of these mosquitoes, the presence of which has continued to increase for almost 20 years in mainland France in a context facilitated by global warming.

            As of October 20, 1,347 cases of dengue fever were detected during the 2023 vigilance period in mainland France, the vast majority imported from French overseas territories or foreign countries.

            In mainland France, indigenous cases are usually observed in southern regions, where the climate is a priori more favorable to the tiger mosquito. The case mentioned by the ARS Île-de-France is therefore the first in a region so far north.

            An “exceptional” year in 2022

            This logically leads to an unprecedented increase in indigenous cases of dengue fever in mainland France: 66 in 2022 and already around thirty for the current year.

            In 2022, the epidemiological situation with regard to dengue in mainland France was “exceptional”, according to a report published this summer by Public Health France. Indigenous transmissions last year alone exceeded the total number of cases identified over 2010-2021 (66 cases, compared to 48).
