How infectious is a human bite?

The likelihood of infection after a human bite is determined by the depth and location of the wound and host factors; the infection rate ranges from 2 percent for superficial wounds, less than 10 percent for occlusal bites, to over 25 percent for clenched-fist wounds or other wounds on the hand [2-4].
