Animal bites occur when an animal's teeth break the skin, potentially causing injury or infection. Common animals that may bite include dogs, cats, snakes, and wild animals. The severity of a bite can vary, ranging from minor scratches to deep wounds that require medical attention. Preventing animal bites involves understanding animal behavior and avoiding situations that may provoke an animal. If bitten, it is important to clean the wound thoroughly and seek medical care, especially if the animal is unknown or unvaccinated. Vaccinations, such as for rabies, can help protect against serious infections.
