How does physical illness affect vampyres?
It has been proposed that vampires are subject to illnesses, viruses, and other nasty bugs much the way mortals are. At the very least, the victims of an infected vampire will contract the illness or virus. However (and this is only my opinion), because the mythology generally considers the vampire to be ‘undead,’ a vampire would be an unsuitable host for any nasty bugs, which tend to prefer warm, wet and living tissue, unlike vampire flesh. The category of nasty bugs should include (again, in my opinion) the AIDS virus and any organism that is incapable of living outside of a host for a long period of time.
