Is there a better way to say "steal a disease"? I feel like "steal a disease" doesn't make much sense, but there's really no better way of saying it. By "steal a disease" I mean transfer the disease from another person and into yourself, thereby curing the person you stole from. I really can't think of a better way to say this.
There is an alleged process of transferring the disease in voodoo practices. For example
