Journal of Applied Ecology 07/11/16 Challenging the conceptual framework of maintenance hosts for influenza A viruses in wild birds. THE LANCET 19/05/17 Stopping emerging influenza viruses at their origin. During the past 100 years, two of four influenza virus pandemics originated in Asia.
Additionally, many of the emerging influenza viruses that are deemed to have pandemic potential, including H5N1, H5N6, H6N1, H7N9, and H10N8, have crossed the species barrier from animals to human beings in Asia.1, 2, 3, 4, 5, 6 One reason for this might be the extensive interface between human beings, domestic poultry, and wild waterfowl, which is generated by the high human population density, the high density of domestic poultry, and ample opportunities for domestic birds to be exposed to wild waterfowl in some regions of Asia.
This environment provides avian influenza viruses with the opportunity to evolve, reassort, and, ultimately, infect human beings. Although zoonotic infections might have high case-fatality rates, it is unlikely that a fully avian virus will cause the next pandemic. Efforts to create vaccines against avian influenza viruses of concern have mainly focused on H5 and H7 viruses. VIRUS EVOLUTION 18/03/17 Adaptation of avian influenza virus to a swine host.

PLOS 09/03/17 Discordant detection of avian influenza virus subtypes in time and space between poultry and wild birds; Towards improvement of surveillance programs. Abstract Avian influenza viruses from wild birds can cause outbreaks in poultry, and occasionally infect humans upon exposure to infected poultry.
Identification and characterization of viral reservoirs and transmission routes is important to develop strategies that prevent infection of poultry, and subsequently virus transmission between poultry holdings and to humans. Int. J. Environ. Res. Public Health 2017, 14(3), 263; Comparative Epidemiology of Human Fatal Infections with Novel, High (H5N6 and H5N1) and Low (H7N9 and H9N2) Pathogenicity Avian Influenza A Viruses. This study aimed to assess the mortality risks for human infection with high (HPAI) and low (LPAI) pathogenicity avian influenza viruses.
The HPAI case fatality rate (CFR) was far higher than the LPAI CFR [66.0% (293/444) vs. 68.75% (11/16) vs. 40.4% (265/656) vs. 0.0% (0/18) in the cases with H5N1, H5N6, H7N9, and H9N2 viruses, respectively; p < 0.001]. Similarly, the CFR of the index cases was greater than the secondary cases with H5N1 [100% (43/43) vs. 43.3% (42/97), p < 0.001]. Old age [22.5 vs. 17 years for H5N1, p = 0.018; 61 vs. 49 years for H7H9, p < 0.001], concurrent diseases [18.8% (15/80) vs. 8.33% (9/108) for H5N1, p = 0.046; 58.6% (156/266) vs. 34.8% (135/388) for H7H9, p < 0.001], delayed confirmation [13 vs. 6 days for H5N1, p < 0.001; 10 vs. 8 days for H7N9, p = 0.011] in the fatalities and survivors, were risk factors for deaths.

PLOS 23/11/16 Avian Influenza Risk Surveillance in North America with Online Media. Abstract The use of Internet-based sources of information for health surveillance applications has increased in recent years, as a greater share of social and media activity happens through online channels.
The potential surveillance value in online sources of information about emergent health events include early warning, situational awareness, risk perception and evaluation of health messaging among others. The challenge in harnessing these sources of data is the vast number of potential sources to monitor and developing the tools to translate dynamic unstructured content into actionable information. In this paper we investigated the use of one social media outlet, Twitter, for surveillance of avian influenza risk in North America. We collected AI-related messages over a five-month period and compared these to official surveillance records of AI outbreaks.

Infectious Diseases of Poverty (2015) 4:50 Prediction of the next highly pathogenic avian influenza pandemic that can cause illness in humans. During the past decade, an endless stream of avian influenza viruses (AIVs), including H1N1, H5N1, and H7N9, has emerged, leading to humans developing malignant respiratory diseases.
The variation trend of influenza viruses needs to be urgently studied. In 1918, the Spanish flu, which was later confirmed as the H1N1 influenza virus, caused at least 20 million deaths worldwide (incomplete statistic) [1, 2]. Why was the Spanish flu so dangerous, and is there a possibility that there could be another outbreak like this in the future?
These questions cannot be sufficiently answered using the current studies. In this paper, we attempt to answer these questions using new bioinformatic systems.

Anna Gillman, MD, PhD1,2* 1Section for Infectious Diseases, Department of Medical Sciences, Uppsala University, Uppsala, Sweden; 2Zoonosis Science Centre, Department of Medical Biochemistry and Microbiology, Uppsala University, Uppsala, Sweden Oseltamivir is the best available anti-influenza drug and has therefore been stockpiled worldwide in large quantities as part of influenza pandemic preparedness planning.
The active metabolite oseltamivir carboxylate (OC) is stable and is not removed by conventional sewage treatment. Active OC has been detected in river water at concentrations up to 0.86 µg/L. Although the natural reservoir hosts of influenza A virus (IAV) are wild waterfowl that reside in aquatic environments, the ecologic risks associated with environmental OC release and its potential to generate resistant viral variants among wild birds has largely been unknown.

Applied Biosafety Vol. 16, No. 1, 2011 Effect of Drying and Exposure to Vaporous Hydrogen Peroxide on the Inactivation of Highly Pathogenic Avian Influenza (H5N1) on Non-porous Surfaces.
This study demonstrated the combined effect of drying and vaporous hydrogen peroxide exposure on inactivating highly pathogenic avian influenza (H5N1) on the non-porous materials glass, Hypalon® rubber glove, and stainless steel. Approximately 7.7 log10 TCID50 (median 50% tissue culture infectious dose)/mL of A/Vietnam/1203/2004 H5N1 in allantoic fluid was dried on coupons of each type of test surface and exposed to vaporous hydrogen peroxide fumigation within a ∼15 m3 chamber.
A significant reduction in the total log10 TCID50 of H5N1 on all test materials was observed between the controls evaluated after a 1-hour drying time and unexposed controls evaluated after decontamination. The H5N1 exhibited a 2–3 log decrease in viability, and vaporous hydrogen peroxide further inactivated the virus to below detectable levels. In parallel Geobacillus stearothermophilus biological indicators exposed to vaporous hydrogen peroxide exhibited no growth after 1 and 7 days' incubation.

VETERINARY RESEARCH - 2014 - The NS segment of H5N1 avian influenza viruses (AIV) enhances the virulence of an H7N1 AIV in chickens. The pathogenic potential of some strains of IAV has been related to multiple factors, including viral determinants and an excessive host immune response [32–41]. Since most of these descriptions have been done in mammals, in the present study we tried to extend these studies to natural hosts of AIV. More specifically, we focused our studies on the understanding of the role that the AIV NS-segment of two different H5- HPAIV strains plays during pathogenesis in birds.
To this end, an experimental infection in SPF-chickens was designed with an H7N1 HPAIV (FPV) and two reassortants carrying the NS-segment of H5N1 HPAIV from either GD (FPV NS GD) or VN (FPV NS VN). Amino acid changes in the viral hemagglutinin and polymorphisms in the polymerase subunit have been shown to contribute to the virulence of AIV . Amino acid differences or substitutions in the NS1 protein are described to alter its subcellular localization [44, 45].

WebImagesPlus… JOURNAL OF INFECTIOUS DISEASE 29/10/14 How Low Is the Risk of Influenza A(H5N1) Infection? For over a decade, we have heard predictions that avian influenza A(H5N1) may be nearing pandemicity and that the pandemic will be catastrophic when it arrives.
These predictions derive from a belief that A(H5N1) may be only a few mutations away from full adaptation to transmissibility  and from its allegedly high propensity to infect and to kill people. The World Health Organization (WHO) has recorded a case-fatality ratio of 59% among the 650 human cases reported to date , which some interpret to mean that approximately 60% of everyone infected by A(H5N1) will die. In the current climate of alarm, routine and decades-old virologic research approaches, such as examining the effects of engineered mutations on phenotypic properties like experimental virulence and transmissibility, recently termed “gain of function” studies, have been called “absolutely crazy” and “exceedingly dangerous” (Robert May, as quoted in Ref. ).

H5N1 influenza continues to smolder in Southeast Asia over the past 5 years, but the emergence of H7N9 in China in 2012 raised concerns for a new avian influenza threat. In contrast with H5N1 with over 650 confirmed cases over 11 years, H7N9 has infected over 450 persons within 2 years. The case fatality rate for H7N9 (35 %) is lower than for H5N1 (60 %) or H10N8 (67 %) but is comparable to that for the Middle East respiratory syndrome coronavirus (MERS CoV), another emerging zoonosis with travel-associated importations.
