I was over dramatizing the situation a bit since I see most viruses from drinking water looks to be vomiting and faulty back door complaints. I was trying to remember the AquaMira name last night and couldn't that's why I threw in Iodine as a possibility.
AquaMira sounds like the way to go. The Sawyer should filter out all the beaver fever and other nasties and if the AqauaMira kills viruses in minutes then a few drops a few minutes before filtering the water seems like the way to go to me. I was more or less wondering if it was a common thing to get viruses in the backwoods which doesn't seem to be the case so I may very well take my chances since most of hiking is done in areas leading away from human habitation.
