Rabies is an acute infectious disease caused by the rabies virus, which can cause rabies infection in humans after an animal has been injured by this virus. Wounds that do not require rabies vaccination include the following cases: 1. When contacting a rabid animal host or a patient with a rabies attack, there is only simple physical contact, and there are no breaks or scratches on the skin, which is a Class I exposure. 2. According to the WHO rabies vaccination guidance program, if a full rabies vaccination has been given within 3 months, a minor bite or scratch by a dog or cat again can be done without rabies vaccination because this is a Class II exposure, and the protection period of the vaccine is valid for at least six months, but the wound still needs to be cleared and disinfected; 3. Animal bites do not require rabies vaccination, regardless of the type of wound. In addition, after being bitten by an animal, timely wound disinfection and injection of the first dose of rabies vaccine, within 10 days of observation of the wounded animal did not occur rabies, can not be vaccinated with subsequent doses of rabies vaccine. For groups that have frequent contact with animals, such as cats and dogs, or who often work in the field, early vaccination is recommended.
