Are you interested in the science behind the H1N1 outbreak?  If so, you need to check out the Science Insider Blog.  It has a very interesting interview about the H1N1 virus causing our current outbreak with Virologist Ruben Donis, chief of the molecular virology and vaccines branch at the CDC.

CDC’s early investigation raises several thought-provoking possibilities. It appears that this outbreak may have been a decade in the making and was not a sudden burst onto the viral stage…apparently flu viruses in swine have been “hooking up” and combining strains from several species. In fact they are speculating that the first infected human may not even have been in North America, let alone Mexico. Patient samples from Mexico taken over the past several months reveal that this swine flu clearly exploded in late March – leading to the theory that it was not rapidly spreading in that country, undetected, for very long.
