In the exposure level of rabies, the bare skin is slightly bitten or scratched or scraped without bleeding, which obviously belongs to this level. It is judged that people exposed to rabies should immediately treat the wound and vaccinate against rabies. If it is confirmed as Class II exposure and the immune function is low, or Class II exposure is located in the head and face and the health of the injured animal cannot be determined, it shall be treated as Class III exposure.
Therefore, whether the skin is damaged is the key to whether vaccination is needed.
