Abstract

BackgroundDiseases caused by Aedes-borne viruses, such as dengue, Zika, chikungunya, and yellow fever, are emerging and reemerging globally. The causes are multifactorial and include global trade, international travel, urbanisation, water storage practices, lack of resources for intervention, and an inadequate evidence base for the public health impact of Aedes control tools. National authorities need comprehensive evidence-based guidance on how and when to implement Aedes control measures tailored to local entomological and epidemiological conditions.Methods and findingsThis review is one of a series being conducted by the Worldwide Insecticide resistance Network (WIN). It describes a framework for implementing Integrated Aedes Management (IAM) to improve control of diseases caused by Aedes-borne viruses based on available evidence. IAM consists of a portfolio of operational actions and priorities for the control of Aedes-borne viruses that are tailored to different epidemiological and entomological risk scenarios. The framework has 4 activity pillars: (i) integrated vector and disease surveillance, (ii) vector control, (iii) community mobilisation, and (iv) intra- and intersectoral collaboration as well as 4 supporting activities: (i) capacity building, (ii) research, (iii) advocacy, and (iv) policies and laws.ConclusionsIAM supports implementation of the World Health Organisation Global Vector Control Response (WHO GVCR) and provides a comprehensive framework for health authorities to devise and deliver sustainable, effective, integrated, community-based, locally adapted vector control strategies in order to reduce the burden of Aedes-transmitted arboviruses. The success of IAM requires strong commitment and leadership from governments to maintain proactive disease prevention programs and preparedness for rapid responses to outbreaks.

Abstract

Background Trypanosomes are protozoan parasites of vertebrates that are of medical and veterinary concern. A variety of blood-feeding invertebrates have been identified as vectors, but the role of ticks in trypanosome transmission remains unclear. Methods In this study, we undertook extensive molecular screening for the presence and genetic diversity of trypanosomes in field ticks. Results Examination of 1089 specimens belonging to 28 tick species from Europe and South America led to the identification of two new trypanosome strains. The prevalence may be as high as 4% in tick species such as the castor bean tick Ixodes ricinus, but we found no evidence of transovarial transmission. Further phylogenetic analyses based on 18S rRNA, EF1-α, hsp60 and hsp85 gene sequences revealed that different tick species, originating from different continents, often harbour phylogenetically related trypanosome strains and species. Most tick-associated trypanosomes cluster in a monophyletic clade, the Trypanosoma pestanai clade, distinct from clades of trypanosomes associated with transmission by other blood-feeding invertebrates. Conclusions These observations suggest that ticks may be specific arthropod hosts for trypanosomes of the T. pestanai clade. Phylogenetic analyses provide further evidence that ticks may transmit these trypanosomes to a diversity of mammal species (including placental and marsupial species) on most continents.

Abstract

Background: Over the past decades, several viral diseases transmitted by Aedes mosquitoes—dengue, chikungunya, Zika—have spread outside of tropical areas. To limit the transmission of these viruses and preserve human health, the use of mosquito traps has been developed as a complement or alternative to other vector control techniques. The objective of this work was to perform a systematic review of the existing scientific literature to assess the efficacy of interventions based on adult mosquito trap to control Aedes population densities and the diseases they transmit worldwide. Methods and findings: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic review was conducted using the PubMed and Scopus databases. Among the 19 selected papers, lethal ovitraps were used in 16 studies, host-seeking female traps in 3 studies. Furthermore, 16 studies focused on the control of Ae. aegypti. Our review showed great heterogeneity in the indicators used to assess trap efficacy: e.g., the number of host-seeking females, the number of gravid females, the proportion of positive containers, the viral infection rate in female mosquitoes or serological studies in residents. Regardless of the type of studied traps, the results of various studies support the efficacy of mass trapping in combination with classical integrated vector control in reducing Aedes density. More studies with standardized methodology, and indicators are urgently needed to provide more accurate estimates of their efficacy. Conclusions: This review highlights gaps in the demonstration of the efficacy of mass trapping of mosquitoes in reducing viral transmission and disease. Thus, further large-scale cluster randomized controlled trials conducted in endemic areas and including epidemiological outcomes are needed to establish scientific evidence for the reduction of viral transmission risk by mass trapping targeting gravid and/or host-seeking female mosquitoes. Author summary: Over the past decades, several viral diseases transmitted by Aedes mosquitoes—dengue, chikungunya, Zika—have spread outside of tropical areas. To limit the transmission of these viruses and preserve environment and human health, the use of mosquito traps has been developed as a complement or alternative to other vector control techniques. This review support the efficacy of mass trapping in combination with classical integrated vector control on the reduction in mosquito vector populations within several weeks of deployment. However, this research highlights gaps in the demonstration of the efficacy of mass trapping of mosquitoes in reducing viral transmission and disease. Thus, further studies are needed to establish scientific evidence for the reduction of viral transmission risk by mass trapping targeting gravid and/or host-seeking female mosquitoes.

Abstract

The Common bed bug, Cimex lectularius, had virtually disappeared from France in the 1950s; however, a worldwide resurgence of bed bugs (C. lectularius and C. hemipterus) has been observed since the 1990s. To document modern pest control activities for the management of bed bugs, a survey was conducted in metropolitan France among the two main categories of professionals regularly called upon to deal with the control of infestations: Municipal Health and Safety Services (MHSSs) and private Pest Management Companies (PMCs). These professionals responded to a questionnaire targeting their knowledge, attitude and practices related to the process for diagnosing a bed bug infestation and the processes taken to actually control an infestation. There were 68 responses received from MHSSs and 51 from the PMCs. The responses indicate that every single département (French administrative division) in metropolitan France has witnessed at least one intervention for bed bugs. Among the criteria considered sufficient to confirm a bed bug infestation, direct observation of bugs was the most commonly cited response. Faced with an infestation, most PMCs used a combination of non-chemical and chemical methods, and systematically performed two treatments. This survey is the first of professionals involved in bed bug control in metropolitan France and confirms the growing importance of bed bugs as a public health pest. Establishing a database to monitor this emerging pest would improve the understanding of the distribution of these insects, help guide educational requirements, identify research needs and assist in ensuring that the most appropriate control practices are undertaken.

Abstract

Biological invasions are responsible for tremendous impacts globally, including huge economic losses and management expenditures. Efficiently mitigating this major driver of global change requires the improvement of public awareness and policy regarding its substantial impacts on our socio-ecosystems. One option to contribute to this overall objective is to inform people on the economic costs linked to these impacts; however, until now, a reliable synthesis of invasion costs has never been produced at a global scale. Here, we introduce InvaCost as the most up-to-date, comprehensive, harmonised and robust compilation and description of economic cost estimates associated with biological invasions worldwide. We have developed a systematic, standardised methodology to collect information from peer-reviewed articles and grey literature, while ensuring data validity and method repeatability for further transparent inputs. Our manuscript presents the methodology and tools used to build and populate this living and publicly available database. InvaCost provides an essential basis (2419 cost estimates currently compiled) for worldwide research, management efforts and, ultimately, for data-driven and evidence-based policymaking.

30. La scénographie à l’épreuve de la fragmentation des espaces d’exposition

Author

Jourdain, Frédéric

Abstract

Nous partirons du postulat que toute exposition confronte le spectateur à des espaces discontinus et morcelés et à des objets (expos, textes, etc…) hétérogènes. Nous entendrons explorer les réponses qu’offrent les grands modèles scénographiques au défi de la fragmentation de l’expérience du spectateur. Pour mettre notre réflexion à l’épreuve d’une étude de cas remarquable par sa singularité et sa complexité, nous prendrons appui sur la scénographie de l’exposition des travaux d’Emilie Faïf à la fondation espace écureuil pour l’art contemporain à Toulouse (Automne 2014). We will work on the premise that any exhibition confronts the audience with discontinuous, fractured spaces and heterogeneous objects (exhibits, texts, etc.). We will consider how the principal exhibition designs respond to the challenge of the fragmented experience of the visit. In testing our thoughts against a unique and complex case study, we will consider the design for the Emilie Faïf exhibition at the Fondation Ecureuil pour l’Art Contemporain in Toulouse (Autumn 2014).

Abstract

International audience; In October 2014, 12 autochthonous chikungunya cases, 11 confirmed and 1 probable, were detected in a district of Montpellier, southern France, a town colonized by the vector Aedes albopictus since 2010. An imported case from Cameroon living in the same district that the autochtonous case was identified as the index case. The epidemiological investigations and the numerous vector control treatments performed in the area and around places frequented by cases helped to contain the outbreak.While the chikungunya and dengue surveillance system in mainland France had been challenged by numerous imported cases due to the chikungunya epidemic ongoing in the Caribbean Islands, this first significant outbreak of chikungunya in Europe since the 2007 Italian epidemic was due to an imported case from Africa. This episode reminds us that the risk of a chikungunya epidemic is now present within the European population.; En octobre 2014, 12 cas autochtones de chikungunya (11 cas confirmés et 1 cas probable) sont survenus à Montpellier, ville colonisée par le moustique vecteur Aedes albopictus depuis 2010. Un cas importé du Cameroun, vivant dans le même quartier que les cas autochtones, a été identifié comme le cas index. Les investigations épidémiologiques et les nombreux traitements de lutte antivectorielle réalisés dans le quartier et autour des lieux fréquentés par les cas lors de leur période virémique ont contribué à contenir l’épidémie.Alors que le système national de surveillance renforcée du chikungunya et de la dengue était, au même moment, fortement impacté par l’épidémie de chikungunya en cours dans les Caraïbes, ce premier foyer d’importance en Europe depuis l’épidémie de 2007 en Italie est consécutif à un cas importé d’Afrique. Cet épisode rappelle que le risque d’épidémie de chikungunya est bien réel pour la population européenne.

Abstract

Arboviruses viruses transmitted by haematophagous arthropods are responsible for febrile syndromes, which sometimes include haemorrhagic or neurological symptoms. Human activities have facilitated the emergence of these originally zoonotic viruses and the domestication and spread throughout the world of their major vectors. The last decade has seen significant changes in the epidemiology of arboviruses transmitted by mosquitoes of the genus Aedes, particularly in relation to the intercontinental spread of Aedes albopictus. Here, we address the epidemiological consequences of the invasion by this species into Central Africa and Europe in a context of viral globalization. The risk of transmission in these areas is influenced by virus-vector adaptation phenomena as well as environmental phenomena including climate. Faced with these new risks, it is essential to develop competences in entomological and virological surveillance, risk assessment and forecasting of epidemic risk in order to develop strategies for the prevention and control of epidemics.

Abstract

La presente expertise a pour principal objectif de proposer des axes d'amelioration de la strategie de surveillance et de controle des Culicoides, vecteurs du virus de la fievre catarrhale du mouton (FCM), suite a la saisine de la Direction Generale de l'Alimentation. Concernant le reseau de surveillance deja en place, il est prioritaire d'effectuer une analyse des donnees recueillies depuis 2009, afin d'identifier les pieges fonctionnant de maniere homogene, ce qui pourrait permettre d'alleger le reseau de surveillance. De plus, il s'agit d'un prealable indispensable pour declarer des periodes d'inactivite des populations de Culicoides par zone sur le territoire metropolitain. Il est egalement propose d'adapter la frequence de piegeage a un rythme de deux nuits de capture successives toutes les deux semaines pendant toute l'annee, au lieu d'une nuit de capture hebdomadaire ou mensuelle selon la saison, ce qui represente le meme nombre de piegeages dans l'annee mais permet de suivre plus finement la dynamique des populations. Une analyse critique des mesures de police sanitaire imposees par la reglementation europeenne a ete realisee. Les enquetes visant a determiner la presence et la distribution des vecteurs dans les elevages suspectes d'etre infectes presentent un interet limite en termes d'evaluation et de gestion du risque, et se heurtent de plus a l'impossibilite operationnelle actuelle de realiser de telles enquetes. L'analyse de la litterature ne permet pas de statuer sur l'efficacite des mesures de confinement des animaux, en raison du degre d'endophagie des vecteurs qui varie fortement selon les especes. En l'etat actuel des connaissances sur les gites larvaires et les sites de repos, les traitements insecticides dans l'environnement sont a proscrire etant donne leur impact environnemental. Il n'existe pas de donnees permettant de juger de l'efficacite de traitements insecticides des batiments ou des vehicules de transport. Quant aux traitements insecticides des animaux, s'ils n'offrent pas une protection a 100 % contre les piqures de Culicoides, meme si ils doivent en theorie diminuer l'intensite de la transmission : c'est donc la seule mesure de lutte anti-vectorielle a envisager en l'absence de vaccin en prenant en compte l'impact environnemental. Ce rapport presente les axes de recherche a developper en priorite, a savoir l'analyse statistique des donnees de surveillance, le developpement d'outils d'identification morphologique et moleculaire, l'etude de la competence vectorielle des differentes especes dont on suspecte le role vectoriel et la modelisation de la distribution spatiale des especes d'interet. Dans le domaine de la lutte anti-vectorielle, il convient d'evaluer precisement l'efficacite des mesures de lutte au laboratoire et sur le terrain, ainsi que l'impact de ces mesures sur l'environnement et en particulier la faune non cible. Les recommandations de lutte anti-vectorielle consignees dans de ce document ont ete etablies sur la base d'etudes menees dans un contexte de transmission du virus de la FCM par les Culicoides, mais sont egalement valables dans le contexte de la transmission par les Culicoides du virus de Schmallenberg recemment apparu en Europe.

Abstract

International audience; Recent events with the first cases of local transmission of chikungunya and dengue fever virus in southern France by Aedes albopictus, adding to the nuisance and potential vectors that can be encountered when traveling in tropical or sub-tropical countries, has shown the value of a reflection on the Personal protection against vectors (PPAV). It is seen during an outbreak of vector-borne disease, or simply because of nuisance arthropods, that our fellow citizens try to protect themselves individually by using an arsenal of resources available on the market. Yet most of these means have been neither checked for effectiveness or safety tests, however, essential. Travellers, staff on mission or assignment, are looking for specific information on how to protect themselves or their families. Health workers had at their disposal so far indications that vary widely from one source to another. Therefore it seemed important to the Society of Travel Medicine (SMV) and the French Society of Parasitology (SFP) to initiate a reflection on this theme. This reflection took the form of recommendations for good practice, following the outline established by the French High Health Authority (HAS). The aim was to gather all relevant information, verified and validated and the format to be used not only by health personnel (doctors, pharmacists, nurses), but also by travel agents and individuals. This document highlights the need to take into account the risk of vector-borne diseases, some deadly, and the benefit of various methods of personal protection. The choice of methods is clearly oriented towards those whose effectiveness has been proven and potential risks assessed. The paper finally proposes two decision trees based on the transmission type (day or night) and kind of stay (short or roaming, long and steady). It concerns travellers, but also expatriates, residents and nomads.

Abstract

Background: Aedes aegypti and Aedes albopictus are the main vectors for the transmission of several viral pathogens, in particular, dengue, Zika and chikungunya. In the absence of vaccines and treatment, control of Aedes mosquitoes is the only means of keeping these diseases in check. Aedes control is difficult, and it is, therefore, necessary to evaluate the efficacy of novel control methods, particularly those targeting adult and exophilic Ae. albopictus populations. Methods: We carried out the first evaluation of the effectiveness of a field trap barrier system, i.e. a “removal trapping” outdoor control strategy for Ae. albopictus in southern France. Results: The removal trapping control strategy is an effective system, able to reduce to almost zero the biting rate of the tiger mosquito in and around houses with traps installed. This strategy has the advantage of being a non-chemical method, which is environmentally friendly and does not affect non-target fauna. Nevertheless, it has several constraints including the cost of the CO2 required for the system to function. However, the system could be optimized by reducing the costs and combining it with other control strategies within the framework of integrated vector management. Conclusions: We provide the first evidence of the effectiveness of this trap barrier system, which is based on the combined effect of (i) removing adult mosquitoes living in the area, and (ii) hampering the migration of mosquitoes from outside into the treated area. Further investigation is needed to understand its efficacy for other species, other locations and at-risk communities, and to evaluate its application for reducing the prevalence of dengue, Zika and chikungunya diseases.

Abstract

BackgroundWastewater surveillance is an effective approach to monitor population health, as exemplified by its role throughout the COVID-19 pandemic.AimThis study explores the possibility of extending wastewater surveillance to the Paris 2024 Olympic and Paralympic Games, focusing on identifying priority pathogen targets that are relevant and feasible to monitor in wastewater for these events.MethodsA list of 60 pathogens of interest for general public health surveillance for the Games was compiled. Each pathogen was evaluated against three inclusion criteria: (A) analytical feasibility; (B) relevance, i.e. with regards to the specificities of the event and the characteristics of the pathogen; and (C) added value to inform public health decision-making. Analytical feasibility was assessed through evidence from peer-reviewed publications demonstrating the detectability of pathogens in sewage, refining the initial list to 25 pathogens. Criteria B and C were evaluated via expert opinion using the Delphi method. The panel consisting of some 30 experts proposed five additional pathogens meeting criterion A, totalling 30 pathogens assessed throughout the three-round iterative questionnaire. Pathogens failing to reach 70% group consensus threshold underwent further deliberation by a subgroup of experts.ResultsSix priority targets suitable for wastewater surveillance during the Games were successfully identified: poliovirus, influenza A virus, influenza B virus, mpox virus, SARS-CoV-2 and measles virus.ConclusionThis study introduced a model framework for identifying context-specific wastewater surveillance targets for a mass gathering. Successful implementation of a wastewater surveillance plan for Paris 2024 could incentivise similar monitoring efforts for other mass gatherings globally.

Abstract

France faced an unusual situation of dengue transmission in 2022, with 65 autochthonous cases spread over nine transmission events by 21 October. This exceeded the number of cases observed during the entire period 2010 to 2021. Six of these events occurred in departments that had never experienced autochthonous dengue transmission. We provide an update of dengue surveillance data in mainland France in 2022. The multiplication of transmission events calls for continuous adaption of preparedness and response to arbovirus-related risks.
