Bites of the hand generally have a high risk for infection because of the relatively poor blood supply of many structures in the hand and anatomical considerations that make adequate cleansing of the wound difficult. In general, the better the vascular supply and the easier the wound is to clean (ie, laceration vs puncture), the lower the risk for infection.
