Scabies question - any mite experts out there?

Factual Questions
1

I’ve hesitated to ask this question because I keep figuring if I just ask Google the right way, my anwer will magically appear. So far, no luck.

Some info I’ve picked up from here suggests that scabies and mange are closely related:

What I’m trying to figure out is: If a person is exposed to mange, would that person be vulnerable to having scabies appear in several days, instead of the 4-6 weeks for a person who has never had scabies?

Long story behind the question, but it has driven me nearly as nutsy as the scabies did!!!

Scabies is mange, so the answer is yes, I guess. The dog one will infect humans, but doesn’t like us as host and is eventually gone, while the human variant loves us and will stay as a parasite unless treated.

Thank you for your answer, Karl. I’ve thought that, also, but then I keep coming back to…

Dog mange and human scabies are, I believe, same genus, different species. Humans can develop a reaction with exposure to Rhus radicans (Poison Ivy) but are not sensitized to it by exposure to Rhus typhina (staghorn sumac)

How similar is it in the mite world?

Secondary question came to me in the middle of the night - could a compromised immune system make a person develop a reaction to scabies as if they had been exposed before?

To the second question, you mean that the reaction will occur faster as compared to someone who is not immunocompromised?

Probably yes, and a stronger reaction too.
