Description
- 3rd most common bite (after dogs and cats)
- Most bites (up to 75%) occur during aggressive acts.

- 2 types of bites:
- Occlusional bites: Laceration or crush injury to affected body part:
- Occurs when human teeth bite into the skin
- More prone to infection than animal bites

- Sustained from a clenched fist striking the mouth and teeth of another person
- Occlusional bites: Laceration or crush injury to affected body part:
- With joint relaxation from the clenched position:
- Puncture site sealed
- Oral bacteria inoculated in the anaerobic setting within the joint
- Bacterial inoculation carried by the tendons deeper into the potential spaces of the hand
- Increases chances for a more extensive infection
