A bite injury occurs when the skin is punctured or broken by the teeth of an animal or human. This type of injury can lead to pain, swelling, and bleeding. Depending on the severity, bites can also cause infections, especially if bacteria enter the wound. Common sources of bite injuries include pets like dogs and cats, as well as wild animals. Treatment for bite injuries typically involves cleaning the wound to prevent infection and may require medical attention. In some cases, a healthcare provider may recommend a tetanus shot or antibiotics. It's important to monitor the bite for signs of infection, such as increased redness or pus.
