There's only one reason the bears scratch backs; Baylisascaris transfuga of bear.
This species of helminthes/nematode leave eggs in hide not intestinal tract/stool/feces.
And if you know this, you know to stay far away from any site were they perform this activity of scratching.
Eggs of, take a possible 1200 degrees to destroy.
Life expectancy of mature Baylisascaris transfuga a possible 300 years.
diagnostic testing to find infection, none.
Man is a large enough host to allow species to live for about 20 - 25 yrs after being infected.
@ 20-25 yrs burden is large enough to cause man great discomfort.
The fluids released by Baylisascaris transfuga to help in travels through host & others to promote the life of off spring, cause mental problems in man that will make him take his own life or at least make him wish he was dead.
No Joke, No kidding around - I have the Key to this puzzling question .
