You actually literally can’t kill prions, they aren’t alive, they’re basically the virus debate’s bastard older brother with a rap sheet that’s just a list of all the people they’ve sent to the hospital, and then followed up bankrupting the hospital because literally everything that victim touched has to be scrapped because hospitals usually don’t have the tools required to break down prions enough for it to be safe to keep anything that might have gotten the patient’s prions on it.
