The so-called tertiary exposure to rabies includes contaminated skin mucous membranes, bleeding visible to the naked eye, broken skin, and bat bites. 1. Mucosal contamination: If the mucous membranes of human skin are contaminated by animal saliva, such as dogs, cats and bats. 2. Bleeding visible to the naked eye: One or more parts of the body have been scratched or bitten, which may even cause damage to blood vessels and the dermis, resulting in bleeding visible to the naked eye or exposure of subcutaneous tissue. 3. Skin breaks: generally include tiny skin breaks induced by scratching and cracking of the skin. 4. Bat bites: Post-exposure prophylaxis is needed when there is contact between humans and bats, unless scratches or bites can be ruled out. In addition, rabies is a dangerous disease, so once the patient has been bitten or scratched by dogs or cats, he or she must actively receive rabies vaccination.
