Influenza type A viruses affect humans and other animals and cause significant morbidity, mortality and economic impact. Influenza A viruses are well adapted to cross species barriers and evade host immunity. Viruses that cause no clinical signs in wild aquatic birds may adapt in domestic poultry to become highly pathogenic avian influenza viruses which decimate poultry flocks. Viruses that cause asymptomatic infection in poultry (e.g. the recently emerged A/H7N9 virus) may cause severe…

Challenges of influenza A viruses in humans and animals and current animal vaccines as an effective control measure
TLDR
Several challenges in control of IAVs faced by human and animals are summarized and IAV vaccines for animal use with those application in susceptible populations are discussed.
Outbreak of Swine-origin Influenza A ( H 1 N 1 ) Virus
TLDR
A brief overview on swine flu is presented highlighting the characteristics of the causative virus, the disease and its advances made in its diagnosis, vaccine and control to be adapted in the wake of an outbreak.
SWINE-ORIGIN INFLUENZA A (H1N1) VIRUS: A REVIEW
TLDR
Recommendations for antiviral susceptibility testing, reporting results, and management of patients infected with 2009 pandemic influenza A H1N1, and the use of Oseltamivir (Tamiflu) or ZanamivIR (Relenza) for the treatment are proposed.
SWINE-ORIGIN INFLUENZA A (H1N1) VIRUS: AN OVERVIEW
TLDR
A brief overview on swine flu is presented highlighting the characteristics of the causative virus, the disease and its advances made in its diagnosis, vaccine and control to be adapted in the wake of an outbreak.
SWINE-ORIGIN INFLUENZA A ( H 1 N 1 ) VIRUS : AN OVERVIEW
TLDR
A brief overview on swine flu is presented highlighting the characteristics of the causative virus, the disease and its advances made in its diagnosis, vaccine and control to be adapted in the wake of an outbreak.
Predicting Zoonotic Risk of Influenza A Viruses from Host Tropism Protein Signature Using Random Forest
TLDR
The swift identification of potentialZoonotic strains in the animal population using the zoonotic strain prediction model could provide us with an early indication of an imminent influenza outbreak.
The Thrift of Avian Influenza in Indonesia
TLDR
New reassortant between H PAIV H5N1 and LPAIV H3N8 with resulting virulence attenuation in chicken is reported, indicating possible threat to humans.
Hemagglutinin Stability and Its Impact on Influenza A Virus Infectivity, Pathogenicity, and Transmissibility in Avians, Mice, Swine, Seals, Ferrets, and Humans
TLDR
A stabilized HA protein appears to be necessary for human pandemic potential and should be considered when assessing humanPandemic risk, according to studies reviewed.
Intense circulation of A/H5N1 and other avian influenza viruses in Cambodian live-bird markets with serological evidence of sub-clinical human infections
TLDR
Knowing of periods of increased circulation of avian influenza in markets should inform intervention measures such as market cleaning and closures to reduce risk of human infections and emergence of novel AIVs.
The ecology and adaptive evolution of influenza A interspecies transmission
TLDR
An overview of the ecology and evolutionary adaptations of IAVs is provided, with a focus on a review of the molecular factors that enable interspecies transmission of the various virus gene segments.

Avian influenza viruses in humans.
TLDR
The zoonotic transmission of avian influenza is a rare occurrence, but the greater public health concern is the adaptation of such viruses to efficient human transmission, which could lead to a pandemic.
Evolution and ecology of influenza A viruses.
TLDR
Wild aquatic bird populations have long been considered the natural reservoir for influenza A viruses with virus transmission from these birds seeding other avian and mammalian hosts, but recent studies in bats have suggested other reservoir species may also exist.
Perspectives on influenza evolution and the role of research
TLDR
Future directions in influenza research that will help resolve each of the knowledge gaps include complete genomic and proteomic analysis of both the virus and the host with the prospect of designing new control strategies and the development of genetically resistant hosts.
Equine and canine influenza: a review of current events
TLDR
While these viruses do not appear to be zoonotic, the close association between humans and dogs, and to a lesser extent horses, demands that better surveillance and control strategies for emerging diseases in companion animals within the context of One World, One Health.
History of Swine influenza viruses in Asia.
TLDR
Understanding the long-term evolution and history of SIV in Asia would provide insights into the emergence of influenza viruses with epidemic potential in swine and humans.
Persistent Host Markers in Pandemic and H5N1 Influenza Viruses
TLDR
It is found that a subset of these persistent host markers exist in all human pandemic influenza virus sequences from 1918, 1957, and 1968, while others are acquired as the virus becomes a seasonal influenza virus.
Highly Pathogenic Avian Influenza (H5N1): Pathways of Exposure at the Animal‐Human Interface, a Systematic Review
TLDR
It is demonstrated that despite frequent and widespread contact with poultry, transmission of the H5N1 virus from poultry to humans is rare and collaboration between human and animal health sectors for surveillance, case investigation, virus sharing, and risk assessment is essential to provide the best possible chance for effective mitigation of the impact of H5n1 in both poultry and humans.
Infectivity, Transmission, and Pathology of Human-Isolated H7N9 Influenza Virus in Ferrets and Pigs
TLDR
A ferret model was used to evaluate the infectivity and transmissibility of A/Shanghai/2/2013 (SH2), a human H7N9 virus isolate, which showed limited capacity for airborne infectivity but efficiently transmitted between ferrets via direct contact, but less efficiently by airborne exposure.

TLDR
Enhanced bio-security, active surveillance together with targeted and evidence-based interventions in the poultry production, and marketing system together with poultry vaccination has prevented further human H5N1 disease and minimized outbreaks of poultry disease in Hong Kong.
Multiple reassortment between pandemic (H1N1) 2009 and endemic influenza viruses in pigs, United States.
TLDR
Novel reassortant viruses detected in commercial pig farms in the United States highlight the increasing complexity of influenza viruses within pig populations and the frequency at which viral diversification occurs in this ecologically important viral reservoir.
