A Brief Introduction to Influenza A Virus in Swine
Influenza A viruses (IAV) of the Orthomyxoviridae virus family cause one of the most important respiratory diseases in pigs as well as humans. Repeated outbreaks and rapid spread of genetically and antigenically distinct IAVs represent a considerable challenge for animal production and public health. This overlap between human and animal health is a prime example of the “One Health” concept. Although only subtypes of H1N1, H1N2, and H3N2 are endemic in swine around the world, considerable diversity can be found not only in the hemagglutinin (HA) and neuraminidase (NA) genes, but in the other 6 genes as well.

CDC Health Advisory: Variant Influenza Virus (H3N2v) Infections
This Health Alert Network Health Advisory provides an update on H3N2 variant virus (or “H3N2v”) activity and summarizes CDC’s updated H3N2v case definitions and recommendations for H3N2v surveillance for the summer and fall of 2013. It supersedes the last H3N2v-related HAN Health Advisory, HAN 325, which was issued August 3, 2012. (Source: PandemicFlu.gov RSS Feed for News Releases)

Study Identifies Influenza Viruses Circulating In Pigs And Birds That Could Pose A Risk To Humans
In the summer of 1968, a new strain of influenza appeared in Hong Kong. This strain, known as H3N2, spread around the globe and eventually killed an estimated 1 million people. A new study from MIT reveals that there are many strains of H3N2 circulating in birds and pigs that are genetically similar to the 1968 strain and have the potential to generate a pandemic if they leap to humans. The researchers, led by Ram Sasisekharan, the Alfred H. Caspary Professor of Biological Engineering at MIT, also found that current flu vaccines might not offer protection against these strains...

Threat Of Flu Pandemic Is Real, Say MIT Researchers
Many H3N2 virus strains which are circulating in pigs and birds are genetically very similar to the 1968 "Hong Kong" flu, also an H3N2 strain that spread around the world and eventually killed approximately one million people, a new study carried out at MIT (Massachusetts Institute of Technology) has found. The researchers added that current flu vaccines may not be effective against these H3N2 strains that currently circulate only in animals. Their study has been published in the journal Scientific Reports (May 10th, 2013 issue)... (Source: Health News from Medical News Today)
