Fine. So there are filty conditions existing there at these pig rearing facilities.
Influenza doesn’t develope in manure ponds or filthy conditions: it developes inside biological entities, like ducks (avian flu), pigs (swine flu), and humans.
This particular influenza contains snippets of dna from European swine flu, Asian swine flu, avian flu, and two types of human flu.
The idea that it sprang, fully formed, from pig farms in La Glora, Veracuz, Mexico is suspicious.
