I agree with snake lab and Winged Wolf. IBD is exceeding rare in pythons and has a very long dormancy (potentially 7 years) it is a bit of a boogyman but virus can live a long time away from the host. It isn't so much a physical distance but a mental one. NOTHING must contact an animal that is in Q contact another snake from the collection. If tools are shared they need to be hard surfaced and disinfected long enough to kill virus (if you looked up the disinfectant used and check times and dilutions to kill something like MRSA it should be fine) Remember few if any chemical disinfectants work on contact most require some time to work generally 20-30 min with the chemical damp is long enough.
