What is this bug I found on my maple tree in Pennsylvania

I think you might be thinking of a close relative, called a kissing bug. Looks just like assassin bugs. They will draw blood around people's mouths whilst sleeping (hence the kissing moniker).
I believe the disease is called chagas disease. And I think the way they test for it is by having a clean control kissing bug bite the suspected infected person, then test the bug's feces for chagas.
But, I could be wrong about everything.

Hello; I believe you are correct. I likely got the two bugs mixed up. Good catch.
