a mixture of powdered silver and dittany applied to a fresh bite will seal the wound and allow the victim to live on as a werewolf, although tragic tales are told of knowing victims begging for death rather than becoming werewolves. the wolfsbane potion, invented by damocles, allows the werewolf to keep their human mind during transformation.
a werewolf cannot choose whether or not to transform and will no longer remember who they are and would kill even their best friend given the opportunity once transformed. despite this, they are able to recall everything they have experienced throughout their transformation upon reverting to their human form
lycanthropy is a magical illness known to be spread by contact between saliva and blood; thus, when a transformed werewolf bites a human, the bitten will become a werewolf themselves. most muggles, however, will die from the extent of their injuries in the instance of a werewolf attack as noted by professor marlowe forfang, though some do survive to become werewolves themselves.
