If scratched by a suspected stray cat or dog, depending on the severity of the wound, if there is a break in the skin as well as bleeding, it is best to receive rabies vaccination within 24 hours. If scratched by a cat or dog, the wound should be immediately flushed with soap and water or other weak alkaline cleansing agents, disinfected with iodine-containing preparations or other disinfectants with virus-inactivating potency, and go to an epidemic prevention station for rabies vaccination and rabies globulin within 24 hours. Beyond 24 hours, the rabies virus that may be carried can infect the surrounding nerves through the broken skin tissue, and once the peripheral nerves are infected, they enter the incubation period. When the virus enters the central nervous system, the patient will experience symptoms of a seizure, such as irritability, anxiety, fear of water, fear of wind, muscle spasms, and finally respiratory failure, with a 100% mortality rate due to the fact that there is no cure for rabies. If the patient has been scratched by dogs and cats for a long time, passive immunization preparations such as rabies human immunoglobulin or anti-rabies serum can be considered for direct injection. Passive immunization preparations can be given at the same time as the rabies vaccine, but passive immunization preparations are no longer used 7 days after the first dose of rabies vaccine.
