"The female lays a vast number of eggs, some of which pass into the host’s urine or stool"
Not only the eggs from fluke parasites, but other parasites too with actual microscopic or visual worms can be seen in urine. Hmmm... what about those using urine therapy (I'm not one) - has it never occurred to them about reinfection?
"There have been reports from doctors in Australia of treating people with schistosomiasis who had contracted the disease forty years earlier in Africa. In other words, the flukes were still coupled and still producing eggs."
I actually had a doctor tell me that worms don't live in the body for very long - they were serious! LOL!
