Pigs might have spread the current strain of influenza to humans, attracting worldwide attention, but new Canadian-led research suggests that we might have given pigs the flu in the first place, during the 1918 Spanish flu pandemic.

A group of Canadian and U.S. researchers, writing in the May issue of the Journal of Virology, say experimental testing of how pigs responded to the 1918 Spanish flu supports the theory that the virus was passed on from humans to pigs in 1918, during the Spanish flu pandemic.
