[pct-l] Anyone gotten Giardia on the PCT?

[Kevin Cook]

I've not thru hiked yet, but from every report I've read, it seems like the
illness are always traced back to where large numbers of hikers converged,
ie KM or a hostel/trail angel spot. Obviously one person at least is getting
it elsewhere, but my impression is that most of the cases are being passed
between hikers. I've never carried any hand sanitizer on a backpacking trip,
but I plan to make sure I have some on my thru hike this year.
