After being bitten by someone else’s dog, the first thing that must be done is to deal with the wound strictly, usually after repeatedly rinsing the wound with hydrogen peroxide and saline, and then applying iodine, so that it is considered normal and regular disinfection of the wound. Secondly, it must be understood that the dog has not been regularly vaccinated against rabies, if it is regularly vaccinated against rabies, then the chances of the human body being infected with rabies after being bitten are very low, and there is no need to go to the hospital for rabies vaccination in this case. But if the dog is not properly immunized, the person who was bitten must immediately go to the hospital to inject rabies vaccine, because once the rabies attack, then the mortality rate is close to 100%.
