[pct-l] Giardia

[Shauna]

I never bother to filter in water Olympic  National Park  before I drink
it.  I ignore the warnings at the trail heads.  I'm a bit picky about where
I collect it from as in not downstream from campgrounds.   I've never
gotten sick from drinking unfiltered water.

>The prevalence of giardia seems to be relatively small. I hiked until 
>the late 80s never filtering water or using iodine. When filter 
>manufacturers started producing filters they needed a market, and hence, 
>the big scare about giardia. As Brick said, 4% - 7% of us are carriers.
