Over the years, emergence of novel H5 and H7 highly pathogenic avian influenza viruses (HPAI) has been taking place through two main mechanisms: first, conversion a low into virus, second, reassortment between different genetic segments already in circulation. We investigated summarized literature on emerging HPAI with aim building spatio-temporal database all these recorded conversions reassortments events. subsequently mapped distribution known events, as well species production systems...
Unexpected pathogen transmission between animals, humans and their shared environments can impact all aspects of society. The Tripartite organisations-the Food Agriculture Organization the United Nations (FAO), World Health (WHO), Organisation for Animal (WOAH)-have been collaborating over two decades. inclusion Environment Program (UNEP) with Tripartite, forming 'Quadripartite' in 2021, creates a new important avenue to engage environment sectors development additional tools resources One...
Global disease suitability models are essential tools to inform surveillance systems and enable early detection. We present the first global model of highly pathogenic avian influenza (HPAI) H5N1 demonstrate that reliable predictions can be obtained at scale. Best using spatial predictor variables describing host distributions, rather than land use or eco-climatic variables, with a strong association domestic duck extensively raised chicken densities. Our results also support more systematic...
The fifth epidemic wave of avian influenza A(H7N9) virus in China during 2016-2017 demonstrated a geographic range expansion and caused more human cases than any previous wave. factors that may explain the recent surge incidence remain unknown. We investigated effect anthropogenic, poultry, wetland variables on all waves. Poultry predictor became much important last 2 waves they were previously, supporting assumption wider H7N9 transmission chicken reservoir. show future to northern increase...
Avian influenza (AI) is a highly contagious viral disease affecting poultry and wild water birds, posing significant global challenges due to its high mortality rates economic impacts. Highly pathogenic avian (HPAI) outbreaks, particularly those caused by H5N1 variants, have surged since their first occurrence in 1959. The HPAI clade 2.3.4.4b viruses notably expanded geographical reach, numerous countries, diverse species, now domestic mammals. Using an ecological niche modelling approach,...

A workforce with the adequate field epidemiology knowledge, skills and abilities is foundation of a strong effective animal health system. Field training conducted in several countries to meet increased global demand for such workforce. However, core competencies veterinary have not been identified agreed upon globally, leading development different curricula. Having set can harmonize training. The Food Agriculture Organization United Nations (FAO) initiated collective, iterative,...
In Bangladesh, the poultry industry is an economically and socially important sector, but it persistently threatened by effects of H5N1 highly pathogenic avian influenza. Thus, identifying optimal control policy in response to emerging disease outbreak a key challenge for policy-makers. To inform this aim, common approach carry out simulation studies comparing plausible strategies, while accounting known capacity restrictions. study we perform simulations previously developed influenza...
Highly pathogenic avian influenza H5N1 remains a persistent public health threat, capable of causing infection in humans with high mortality rate while simultaneously negatively impacting the livestock industry. A central question is to determine regions that are likely sources newly emerging strains pandemic potential. suitable candidate Bangladesh, being one most densely populated countries world and having an intensifying farming system. It therefore vital establish key factors, specific...
The Avian Influenza A (H5N1) virus is endemic in poultry Egypt. winter of 2014/2015 was particularly worrying as new clusters HPAI emerged, leading to an important number AI outbreaks farms and sporadic human cases. To date, few studies have investigated the distribution Egypt relation protective / risk factors at farm level, a gap we intend fill. aim study analyse passive surveillance data that were based on observation sudden high mortality or drop duck chicken egg production, basis better...
In the last two decades, important avian influenza viruses infecting humans emerged in China, highly pathogenic (HPAI) H5N1 virus late nineties, and low (LPAI) H7N9 2013. China is home to largest population of chickens (4.83 billion) ducks (0.694 billion), representing, respectively 23.1 58.6% 2013 world stock, with a significant part poultry sold through live-poultry markets potentially contributing spread viruses. Previous models have looked at factors associated HPAI LPAI markets....
SARS-CoV-2 has demonstrated the ability to infect a wide range of animal species. Here, we investigated infection in livestock species Oman and provided serological evidence cattle, sheep, goats, dromedary camel using surrogate virus neutralization plaque reduction tests. To better understand extent animals associated risks, "One Health" epidemiological investigations targeting exposed COVID-19 human cases should be implemented with integrated data analysis epidemiologically linked cases.
In the last few years, several reassortant subtypes of highly pathogenic avian influenza viruses (HPAI H5Nx) have emerged in East Asia. These new viruses, mostly subtype H5N1, H5N2, H5N6 and H5N8 belonging to clade 2.3.4.4, been found Asian countries caused outbreaks poultry China, South Korea, Vietnam. HPAI H5Nx also spread over considerable distances with introduction same 2.3.4.4 U.S. (2014-2015) Europe (2014-2015 2016-2017). this paper, we examine emergence these Asia relation published...
Abstract The highly pathogenic avian influenza (HPAI) H5N1 virus has been circulating in Asia since 2003 and diversified into several genetic lineages, or clades. Although the spatial distribution of its outbreaks was extensively studied, differences clades were never previously taken account. We developed models to quantify associations over time space between different HPAI viruses from clade 1, 2.3.4 2.3.2 agro-ecological factors. found that Mekong region 2004 2013 strongly regionalised,...
Growth in the livestock sector is associated with heightened risk for epidemic diseases. The increasing spillover of new diseases from wildlife being driven by wide-scale anthropogenic changes allowing more frequent and closer wildlife–human wildlife–livestock contacts. An number epidemics are rapid transition systems extensive to intensive, local global movement their products through value chain networks weak biosecurity. Major past two decades have had substantial economic impacts,...
Significant global efforts have been directed towards understanding the epidemiology of highly pathogenic avian influenza (HPAI) across poultry production systems and in wild-bird reservoirs, yet disease dynamics village setting remains limited. This article provides a detailed account first laboratory-confirmed outbreak HPAI south-eastern provinces Lao PDR, which occurred Sekong Province October 2018. Perspectives from an anthropologist conducting fieldwork at time outbreak, clinical...
Lumpy skin disease is one of the fast-spreading viral diseases cattle and buffalo that can potentially cause severe economic impact. Lesotho experienced LSD for first time in 1947 episodes outbreaks occurred throughout decades. In this study, eighteen specimens were collected from LSD-clinically diseased between 2020 2022 Mafeteng, Leribe, Maseru, Berea, Mohales’ Hoek districts Lesotho. A total 11 DNA samples analyzed by PCR sequencing extracellular enveloped virus (EEV) glycoprotein,...
The distribution of farm locations and sizes is paramount to characterize patterns disease spread. With some regions undergoing rapid intensification livestock production, resulting in increased clustering farms peri-urban areas, measuring changes the spatial crucial design effective interventions. However, those data are not available many countries, their generation being resource-intensive. Here, we develop a model (FDM), which allows prediction poultry countries with scarce data....
