Researchers think that the 1918 virus was avian in origin, but research is not conclusive. I’ve read that the current strain has avian, porcine, and human markers. Strange stuff.
Here’s a CDC paper published in Jan., 2006, prior to the current panic and political situation:

A very interesting read.
Whatever the origin, I think we all want it to just go away.
See post 40, who also mentions the pig component. Sure I saw it on a documentary on 1 of those Discovery Channels or such.
Anyway, I still question WHY we’re so worried about this.
