There is no clear statement of the safety period after being bitten by a cat, the human body may be infected with rabies after being bitten by a cat, and the patient should actively go to the hospital for rabies vaccine injection within 24 hours, so the risk period of being scratched by a cat refers to the incubation period of rabies, which is generally ranging from 1 to 3 months. After a cat carrying the rabies virus bites the human body, the rabies virus can enter the human body with the broken skin and mucous membranes, and after entering the human body, the glycoprotein contained in the virus can bind with the human body’s acetylcholine receptor and replicate in the muscle tissue. Thereafter, it enters the bloodstream and invades the peripheral nervous system and central neurons of the body. This process generally takes anywhere from 1 to 3 months, and this is the period of danger for the patient. Patients bitten by cats should actively go to the hospital within 24 hours for rabies vaccination, and use iodophor or alcohol to disinfect the wound repeatedly, during this period to ensure that the affected area is clean and dry, and do not eat spicy and irritating food. Because once rabies, the mortality rate can reach 100%, so after being bitten by a cat, you should go to the hospital in time to do wound debridement, and go to the CDC for rabies vaccine and rabies immune globulin injection within 24 hours.
