4. Wolf attack.
A wolf attacking and biting you is what is said to make you turn into a werewolf. Not many wolf attacks have ever been reported though. One that is on the record is of an Indian village situated in Uttar Pradesh. The report was about a pack of wolves that kept on attacking their village and the people doubted them to be werewolves. Every time the wolves entered the village they were sure to eat a few children, and children are what they seemed to want.
