Pet bites can cause infection. The most dangerous is the bite of a rabid animal. The rabies virus is transmitted through the saliva of an infected animal, such as a dog, cat, fox, or sometimes farm animals. If a person is bitten by an animal, it is necessary to take the victim to a safe place, stop the bleeding, and apply a bandage to the wound. The bitten animal must be examined for rabies. If necessary, the person who is bitten is vaccinated against rabies.
