If you are scratched by a cat and the skin is not broken, you do not need to go to the nearest immunization station for vaccination, but if you are scratched by an unvaccinated cat, you may be infected with rabies virus. The rabies virus mainly enters the subcutaneous nerve tissue through the broken skin, and then enters the central nervous system and develops. Rabies is a malignant infectious disease with no cure and a mortality rate of up to 100%. Therefore, if you are scratched by an unvaccinated cat, you need to go to the nearest vaccination station within 24 hours for rabies vaccination. The rabies vaccination requires five injections over a period of one month, and through the entire vaccination process, the rabies virus can be effectively prevented from infection.
