Pigs can be infected with both human and avian influenza viruses in addition to swine influenza viruses. Infected pigs get symptoms similar to humans, such as cough, fever, and runny nose. Because pigs are susceptible to avian, human and swine influenza viruses, they potentially may be infected with influenza viruses from different species (e.g., ducks and humans) at the same time.[citation needed] If this happens, it is possible for the genes of these viruses to mix and create a new virus.

For example, if a pig were infected with a human influenza virus and an avian influenza virus at the same time, an antigenic shift could occur, producing a new virus that had most of the genes from the human virus, but a hemagglutinin or neuraminidase from the avian virus. The resulting new virus would likely be able to infect humans and spread from person to person, but it would have surface proteins (hemagglutinin and/or neuraminidase) not previously seen in influenza viruses that infect humans, and therefore to which most people have little or no immune protection. If this new virus causes illness in people and can be transmitted easily from person to person, an influenza pandemic can occur

Where did This Mysterious New Animal-Human Flu Strain Come From?

Alongside the fear-mongering headlines, I've also seen increasing numbers of reports questioning the true nature of this virus. And rightfully so.

Could a mixed animal-human mutant like this occur naturally? And if not, who made it, and how was it released?

Not one to dabble too deep in conspiracy theories, I don't have to strain very hard to find actual facts to support the notion that this may not be a natural mutation, and that those who stand to gain have the wherewithal to pull off such a stunt.

Just last month I reported on the story that the American pharmaceutical company Baxter was under investigation for distributing the deadly avian flu virus to 18 different countries as part of a seasonal flu vaccine shipment. Czech reporters were probing to see if it may have been part of a deliberate attempt to start a pandemic; as such a "mistake" would be virtually impossible under the security protocols of that virus.

The H5N1 virus on its own is not very airborne. However, when combined with seasonal flu viruses, which are more easily spread, the effect could be a potent, airborne, deadly, biological weapon. If this batch of live bird flu and seasonal flu viruses had reached the public, it could have resulted in dire consequences.

There is a name for this mixing of viruses; it's called "reassortment," and it is one of two ways pandemic viruses are created in the lab. Some scientists say the most recent global outbreak -- the 1977 Russian flu -- was started by a virus created and leaked from a laboratory.

Another example of the less sterling integrity of Big Pharma is the case of Bayer, who sold millions of dollars worth of an injectable blood-clotting medicine to Asian, Latin American, and some European countries in the mid-1980s, even though they knew it was tainted with the AIDS virus.

So while it is morally unthinkable that a drug company would knowingly contaminate flu vaccines with a deadly flu virus such as the bird- or swine flu, it is certainly not impossible. It has already happened more than once.

Antigenic shift is the process by which at least two different strains of a virus, (or different viruses), especially influenza, combine to form a new subtype having a mixture of the surface antigens of the two original strains. The term antigenic shift is more often applied specifically, (but is not limited) to the influenza literature, as it is the best known example (e.g. visna virus in sheep[1]). Antigenetic shift is a specific case of reassortment or viral shift that confers a phenotypic change.
