Hygene Question

[Dirty]

Hello everyone. I recently had a tragedy with a disease/virus that killed all three of my ball pythons. I'm thinking it was IBD judging from my snake's symptoms (stargazing, regurgitating, sudden death), and that all my other animals seem to be fine. I don't have a qualified vet in my area to do a necropsy to find out for sure. My question is this...My balls tubs were next to my Tokay's cage and I was wondering if it were posssible the disease/virus could be lingering on the tokay, it's cage furniture, or cage itself? I don't want to get any more animals at all until I'm POSITIVE my reptile room is 100% clean. Any help is appreciated. Thank you very much in advance.
