After being bitten by an animal such as a dog or cat, the sooner the rabies vaccine is given, the better, preferably within 24 hours. At present, there is no effective treatment for rabies, prevention is the only way, and once the disease develops, its mortality rate is almost 100%, so if bitten by an animal such as a dog or cat, the first time you are bitten, you should treat the wound by alternately washing and rinsing the bite and scratch thoroughly with 20% soapy water (or other weakly alkaline detergent) and flowing water at a certain pressure for at least 15 minutes. The wound should then be washed with saline (or water instead) and finally the residual fluid should be absorbed with sterile skimmed cotton to avoid residual soap and water or detergent in the wound. For deeper wound irrigation, a syringe or high-pressure pulse instrument is used to reach into the deeper part of the wound for irrigation and cleaning, and then alcohol and iodophor are used for local disinfection treatment. Also assess the wound and be sure to administer rabies vaccine as soon as there is a break in the skin. However, if there is no time to inject within 24 hours, it is still important to get vaccinated so that the vaccine will produce antibodies and immunity in the bite victim’s body and the chances of rabies developing in the bite victim will be reduced. Depending on the condition of the wound, rabies immunoglobulin is sometimes also required to achieve a comprehensive defense. In addition, side effects such as allergy, fever, nausea and vomiting may occur after rabies vaccination, and serious cases require prompt symptomatic treatment at a hospital.
