This may have been asked before, so I apologize if it has. If everyone is infected with the virus, and will change regardless of the cause of death, why does a non lethal scratch या bite cause one to turn into a zombie?
They have the virus inside of them... After having a 'encounter' with an infected and kill it आप still get the infection so if you're sick and die from the sickness आप get आप turn into a walker... Simple as that they कहा it last season when Shane turned. After being stabbed.
