As the number of confirmed cases of swine flu around the globe increases, we grow closer and closer to having a pandemic on our hands. In preparation against that possibility, governments are emphasizing prevention of further human-to-human transmission and treatment for those who are ill. Talk about greater distribution of filter masks, vaccine production, and limitations on international travel abounds. Surprisingly, however, there is very little discussion about how swine flu got started in the first place.
