Treatment

Bite wounds are washed, ideally with povidone-iodine soap and water. The injury is then loosely bandaged, but is not sutured due to risk of infection.

Animal bites inflicted by carnivores (other than rodents) are considered possible cases of rabies. The animal is caught alive or dead with its head preserved, so the head can later be analyzed to detect the disease. Signs of rabies include foaming at the mouth, self-mutilation, growling, jerky behavior, and red eyes. If the animal lives for ten days and does not develop rabies, then it is probable that no infection has occurred.

If the animal is gone, prophylactic rabies treatment is recommended.

The route of administration depends on the depth and severity of the wound, as well as the time that has passed since the bite.
