The common idiom states that pigs cannot fly. I don’t think this statement can be easily debated. However, the swine flu viruses now seem to have flown around the globe quickly (with cases in New Zealand, New York, Canada, California, and of course Mexico). As always, with such things that one cannot easily interpret, both news agencies and conspiracy theorists are always ahead of scientists with a mixture of quasi-scientific, scientifically inaccurate, and entertaining stories (or maybe not).
It is hard with conditions such as the current eventual flu pandemic to get the facts straight. I cannot claim having any additional knowledge, but I would rather read what the World Health Organization (WHO) and the US Centers for Disease Control and prevention (CDC) have to say first:
WHO:
- 24 April 2009: Influenza-like illness in the United States and Mexico
- 26 April 2009: Swine flu illness in the United States and Mexico – update 2
CDC:
- MMWR April 24, 2009 / 58 (Dispatch);1-3
Update: Swine Influenza A (H1N1) Infections — California and Texas, April 2009 - MMWR April 24, 2009 / 58(15);400-402: A case report
Swine Influenza A (H1N1) Infection in Two Children — Southern California, March–April 2009
