Linked to swimming pools?
Or linked to third worlders that now use those swimming pools for more than swimming and aquatic sports?
Nah...just observe all the homeless in San Francisco, Seattle, etc. They are all local born folks, strung out on dope, booze.
Bingo.
I had a five month old German Shepherd puppy get crypto once.
Just getting the diagnosis stumped the vet for months. The obvious guess was giardia. Nope. The pup was tested for everything.
A tech *finally* thought to test for crypto, though it seemed far fetched.
We lived in SoCal back then; but, he was never anywhere near a pool, lake, river, or any public water source.
He tested positive.
The vet doesn’t keep the meds, so I had to get them at a people pharmacy. They aren’t kept in stock there either, it was a special order.
The cost: $150 for five pills. And this was over 15 years ago.
The only possible source I can think of was the mud he has a swell time playing in at a friends’ place when her well pump basically exploded. She has a really unique set up on four acres in Los Angeles. Hmph.
