They aren't entirely sure all of the ways it can be transfered. A few ways is through reproduction between an infected animal, sharing water sources, fecal contamination, mites, saliva, etc. So, in theory, you probably wouldn't transfer the IBD, but it is possible.
I seriously wouldn't risk handling strange animals without sending yourself through a sterilization of sorts.
After visiting someone else's collection, I remove all contaminated clothes and they go directly into the washer. After that, I bathe. I do this same procedure after visiting pet stores, etc.
