Yup.
Had it twice.
The first time it was theorized that while MTBing in the Tahoe area and doing a lot of water crossings, water probably splashed up onto my water bottles and then I transferred it to my mouth.
The second time I had been surfing around the mouth of one of our local rivers. (this last winter) County Health called me. They figured that was where I got it. The stuff can apparently survive in salt water. The other possibility was a restaurant worker that was positive and not washing his hands. Doubtful.
Both times took me out of the water for some time just because of the time it took to get a diagnosis.
On the MTBing thing....
My brother in Oregon got a deer related illness. Not sure what it was, just that it had 'hemorrhagic' in the title. Wasn't giardia though.
Before he came down with it, had been out biking in the coastal range and when the lab results came in the docs said it was some sort of zoonotic transmission from a deer of said germ (found primary in deer or other hoofed animals). They asked him he had hunted or eaten undercooked deer recently and when told, "No", one of the docs suggested that he could have run over deer poop and flicked it up onto himself or aerosolized it, and thence into his body.
Like the ocean, the woods are always willing to kill you for the fun of it.
