“…For this reason, there is high probability of the emergence of humans and animal influenza viruses reassortants, as well as emergence of local outbreaks of human morbidity caused by uncommon variants of influenza viruses. Furthermore, Novosibirsk is the largest transport hub in this part of Russia with numerous international connections, that is important for the spread of ARIs [19,20].…”

BackgroundAcute respiratory infections (ARIs) cause a considerable morbidity and mortality worldwide especially in children. However, there are few studies of the etiological structure of ARIs in Russia. In this work, we analyzed the etiology of ARIs in children (0–15 years old) admitted to Novosibirsk Children’s Municipal Clinical Hospital in 2013–2017.MethodsWe tested nasal and throat swabs of 1560 children with upper or lower respiratory infection for main respiratory viruses (influenza viruses A and B, parainfluenza virus types 1–4, respiratory syncytial virus, metapneumovirus, four human coronaviruses, rhinovirus, adenovirus and bocavirus) using a RT-PCR Kit.ResultsWe detected 1128 (72.3%) samples were positive for at least one virus. The most frequently detected pathogens were respiratory syncytial virus (358/1560, 23.0%), influenza virus (344/1560, 22.1%), and rhinovirus (235/1560, 15.1%). Viral co-infections were found in 163 out of the 1128 (14.5%) positive samples. We detected significant decrease of the respiratory syncytial virus-infection incidence in children with increasing age, while the reverse relationship was observed for influenza viruses.ConclusionsWe evaluated the distribution of respiratory viruses in children with ARIs and showed the prevalence of respiratory syncytial virus and influenza virus in the etiological structure of infections. This study is important for the improvement and optimization of diagnostic tactics, control and prevention of the respiratory viral infections.

“…In particular bioexclusion includes also the separation between wild birds and domestic poultry, due to the risk of introduction of new AIV into the poultry production sector (De Marco et al, 2014;Marché et al, 2014). To achieve bioexclusion in free range poultry (Koch and Elbers, 2006) proposed: (i) Double fencing and roofing (Wintergarten) of the free-range area, excluding access of possibly infected wild birds and other animals to the free-range area, and preventing possible contamination of the area by faecal material from infected wild birds and other animals.…”

An extensive literature review was performed to provide insights on the effect of biosecurity and control measures on the risk of introduction and spread of avian influenza in the domestic poultry sector, whether there are gaps in surveillance on wild birds, and to investigate the trigger thresholds for early detection activities through passive surveillance. A total of 1390 articles were retrieved from on-line databases, including Thomson-Reuters Web of Knowledge, PubMed, Ovid and Medline. After removing duplicates 788 studies were screened, and 194 papers were fully read to evaluate whether they could provide reliable information. Twenty-seven papers were considered relevant for assessing the effect of biosecurity and control measures, 7 were included in the assessment of early detection thresholds, and 66 provided information on surveillance gaps in wild birds. Due to the different types of studies included in the review, it resulted impossible to make direct comparison between the results obtained in the articles, as many of them did not report quantitative assessments of the effects of interest. Instead of a formal comparison between studies, the results were reported to provide recommendations on the research questions, also supplying evidences obtained through quantitative analysis and mathematical modeling. Nevertheless it was possible to assess the likely effects of control measures such as pre-emptive culling of farms nearby infected premises, ring vaccination and compartmentalization. Insights on early detection measures provided useful information to reconsider the passive surveillance thresholds to be accounted for to avoid the undetected circulation of avian influenza. The reporting of surveillance on wild birds allowed to identify species to be integrated within the commonly considered target species, and procedures to optimize activities by focusing on defined areas and temporal periods, in the context of a fine tuned Risk Based Surveillance plan. © IZSVe, 2016Key words: avian influenza, biosecurity, surveillance, early detection, introduction, spread Disclaimer: The present document has been produced and adopted by the bodies identified above as authors.

Background: The aim of the study was to explore the ecological diversity of wild birds in Siberia, which are the natural reservoir of avian influenza virus (AIV). Methods:Cloacal swabs and intestinal fragments were collected from wild migratory birds from 2007-2014. Isolated viruses were grown in the allantoic cavity of embryonated chicken eggs. The presence of virus was determined using hemagglutination assays. Primary identification and subtyping of influenza viruses was confirmed by RT-PCR. Conclusions:Wild migratory waterfowl of orders Anseriformes and Charadriiformes are the main reservoir of AIV in the south of Western Siberia. This area plays a key role in persistence, evolution, and geographical distribution of avian influenza.
