 The transformation is slow, as the spores must first adapt the body to suit the growth of a leech.The only other means of infection are from direct transmission or bodily fluids from a vampire (usually sex or biting), or by absorbing a leech’s egg, and becoming a full-blown "eggson" (or –daughter), or to be born the BloodSon/BloodDaughter of a vampire.The process is slow, and the actual time between infection and full-blown vampirism varies greatly from host to host.
