Recent outbreaks of highly pathogenic avian influenza in Europe have raised questions regarding the epidemiological role commensal wild birds on free-range poultry farms. This study aimed to assess prevalence viruses (AIV), avulaviruses, coronaviruses and Chlamydia sp. a duck farm southwestern France evaluate possible transmission events at wild‒domestic interface. From 2019 through 2021, longitudinal was conducted birds, domestic ducks their shared environment Commensal were captured...
Beginning in 2003, highly pathogenic avian influenza (HPAI) H5N1 virus spread across Southeast Asia, causing unprecedented epidemics. Thailand was massively infected 2004 and 2005 continues today to experience sporadic outbreaks. While research findings suggest that the of HPAI is influenced primarily by trade patterns, identifying anthropogenic risk factors involved remains a challenge. In this study, we investigated which played role using outbreak data from "second wave" epidemic (3 July...
Avian influenza A(H5N8) virus has caused major epizootics in Europe since 2016. We conducted virologic analysis of aerosol and dust collected on poultry farms France during 2020-2021. Our results suggest contributes to viral dispersal, even early an outbreak, could be a valuable surveillance tool.
IntroductionFrance is one of Europe's foremost poultry producers and the world's fifth largest producer meat. In November 2016, highly pathogenic avian influenza (HPAI) virus subtype H5N8 emerged in country. As 23 March 2017, a total 484 confirmed outbreaks were reported, with consequences on animal health socio-economic impacts for producers. Methods: We examined spatio-temporal distribution that occurred France between 2016 using space-time K-function permutation model scan statistic test....

Our departure point was agreed previously by among UK multi-disciplinary panel, which had been subsequently revised consultation with ESCMID Study Group representatives. The 46 draft competency...
Biosecurity is crucial for infectious disease prevention, more importantly in the absence of vaccination. The need improving implementation biosecurity practices was highlighted French duck farms following 2016–2017 H5N8 Highly Pathogenic Avian Influenza (HPAI) epidemic. Farmers have multiple reasons not implementing practices: external (time, money) and internal (socio-psychological). purpose this study to determine how sets socio-psychological factors (i.e. knowledge on avian influenza...
Abstract In winter 2016–2017, Highly Pathogenic Avian Influenza (HPAI) H5N8 virus spread across Europe, causing unprecedented epizootics. France was massively affected, resulting in the culling of over 6 million poultry. Boosted regression tree (BRT) models were used to quantify association between spatial risk factors and HPAI infection poultry holdings generate predictive maps for infection. Three datasets combined build model: a dataset reported outbreaks poultry, where has not been set...
Highly pathogenic avian influenza (HPAI) subtype H5N8 outbreaks occurred in poultry farms France 2016–2017, resulting significant economic losses and disruption to the industry. Current evidence on associations between actual on-farm biosecurity risk factors occurrence is limited. Therefore, a retrospective matched case–control study was undertaken investigate inter-relationships practices infection status provide new insights regarding promising targets for intervention. Data were collected...
Abstract The Highly Pathogenic Avian Influenza H5N1 (HPAI) virus is now considered endemic in several Asian countries. In Cambodia, the has been circulating poultry population since 2004, with a dramatic effect on farmers’ livelihoods and public health. Thailand, surveillance control are still important to prevent any new incursion. Risk mapping can contribute effectively disease systems, but very challenging task absence of reliable data. this work, we used spatial multicriteria decision...
The severe impact of recently reported Highly Pathogenic Avian Influenza (HPAI) outbreaks have emphasized the need to better monitor biosecurity practices among different French poultry production systems. Between October 2016 and September 2018, a large national cross-sectional study was carried out in France assess levels high-risk farms identify farm profiles, using Multiple Correspondence Hierarchical Cluster Analyses. Results indicate that there is substantial room for improvement...
Compliance with required on-farm biosecurity practices reduces the risk of contamination and spread zoonotic economically important diseases. With repeating avian influenza epidemics in poultry industry, need to monitor improve overall level is increasing. In practice, compliance assessed by various actors (e.g., academic, private public institutions), results such assessments may be recorded gathered databases which are seldom shared or thoroughly analyzed. This study aimed provide an...

Abstract The relative roles that movement and proximity networks play in the spread of highly pathogenic avian influenza (HPAI) viruses are often unknown during an epidemic, preventing effective control. We used network analysis to explore devastating epidemic HPAI A(H5N8) among poultry, particular ducks, France 2016–2017 estimate likely contribution live-duck movements. Approximately 0.2% movements could have been responsible for between-farm transmission events, mostly early epidemic....
The spread of highly pathogenic avian influenza (HPAI) viruses worldwide has serious consequences for animal health and a major economic impact on the poultry production sector. Since 2014, Europe been severely hit by several HPAI epidemics, with France being most affected country. Most recently, was again two devastating epidemics in 2020-21 2021-22. We conducted descriptive analysis 2021-22 as first step towards identifying sector's remaining vulnerabilities regarding France. examined...
We analysed the interplay between palmiped farm density and vulnerability of poultry production system to highly pathogenic avian influenza (HPAI) H5N8. To do so, we used a spatially-explicit transmission model, which was calibrated reproduce observed spatio-temporal distribution outbreaks in France during 2016-2017 epidemic HPAI. Six scenarios were investigated, farms decreased municipalities with highest density. For each six scenarios, first calculated spatial basic reproduction number...
In this study, we present a comprehensive analysis of the key spatial risk factors and predictive maps for HPAI infection in France, with focus on 2016–17 2020–21 epidemic waves. Our findings indicate that most explanatory predictor variables were related to fattening duck movements prior epidemic, which should be considered as indicators farm operational status, e.g., whether they are active or not. Moreover, found considering status houses nearby municipalities is essential accurately...
The continuous spread of highly pathogenic avian influenza H5 viruses poses significant challenges, particularly in regions with high poultry farm densities where conventional control measures are less effective.
