Sacriphthisis is a fictional medical technology that allows for the completed transfer of illnesses from one person (a giver) to another (a receiver). the transfer cures the giver completely. Receivers can volunteer to absorb multiple illnesses, but only from one giver and cannot be killed intentionally as part of the process. The proposed program would resemble blood or organ donation systems, with a public registry of volunteers who opt in to receive illnesses from people who request to be cured.
