Unprovoked animal bites are particularly dangerous. The possibility of a cat, dog, or wild animal having rabies is high, especially in less-developed countries. Bites from humans, dogs, and cats often lead to severe infections. Puncture wounds are very dangerous because they inject bacteria deep into the tissues. Bites to the hand, wrist, foot, or joint are very dangerous and require immediate medical attention.
Infection is a major concern with bites.
Local wound infection may develop in as little as 24 hours. All bite wounds require immediate, copious cleansing with fresh tap water. Gently scrub the wound with soap and water to remove foreign material. If a syringe is available, it should be used to provide high-pressure irrigation. Remove dead tissue from the wound with a sterile scissors or scalpel.
