I think you'll get mixed opinions on this but I learned the following standards:
- Quarantine has to be done in a different room from the other animals.
- Use a different enclosure from the one you will be using later. A suitable plastic box with holes is fine.
- Minimalistic setup with just paper towels, a water bowl, hides and the technical setup (heat mat, thermostat, etc.)
- Use different tools that don't come in contact with your other snake. If they don't stay in the enclosure of the new snake, clean them with boiling water after they've come in contact with the animal and/or the enclosure.
- Always clean your hands afterwards. If you can, disinfect them. Maybe even use disposable gloves.
- Only interact with the quarantine enclosure when you're done interacting with your other pets (reptiles) for the day.
- The animal should be quarantined for at least 3 months.
- You should do least 2 fecals in that time frame. They should be done at an interval of at least 2 weeks. (German standard)
- Change the water daily.
- Change the paper towels daily or every second day.
- Check for mites daily.
- Look for signs of IBD (especially with a Boa).
--> It can be that snake will display no signs of IBD even if it's already ill. Boas can have IBD years before
developing symptoms. It's a bit like AIDS in that regard.
This is what I learned. Hope this is helpful to you.
