After being scratched by a cat, especially with blood exposure, there is a certain risk of rabies virus infection. After being scratched by animals, including not only sick dogs, but also other animals such as cats and pigs, sufficient attention must be paid to these animals, which may carry certain viruses in their bodies, especially rabies virus, which can cause infection through broken skin mucous membranes. Once rabies develops, the mortality rate will reach 100%, and there is still no special treatment option, so rabies prevention should be taken seriously. After being scratched by a cat, especially if there is blood exposure, the wound must be treated promptly and formally, strictly disinfected, and then vaccinated throughout, with immunoglobulin if necessary. After such treatment, the incidence of rabies can be reduced to a minimum or even to zero before a safer outcome can be guaranteed.
