If you have cats and dogs at home, you will inevitably get bitten or scratched when you play with them or discipline them. Sometimes I feel that the injury is not serious, so I don't pay attention, causing the wound to become inflamed and infected, or even infected with some serious or fatal diseases, such as rabies. Therefore, after being scratched or bitten by a cat or dog, you must not take it lightly and must deal with it immediately. If you are bitten by a dog, immediately wash the injured area with soap and plenty of water to remove the dog's saliva, and then carefully disinfect the wound and surrounding area with hydrogen peroxide or iodine. If the dog belongs to your own family and has regular vaccinations every year, just pay attention to applying medicine to the wound. If it is a dog outside or without anti-epidemic measures, the injured person must be sent to the hospital for diagnosis and treatment and injected with rabies vaccine. At the same time, the biting dog must be isolated and observed, and a rabies examination must be performed. Generally speaking, cats rarely bite people, and there is a greater chance of being scratched by a cat. If you are scratched by a cat, you should not ignore the small scratches. You must first wash them with soap and water, and then carefully disinfect them with hydrogen peroxide and iodine. If you are bitten by a cat, especially a stray cat outside, the cat may also carry rabies bacteria, so the treatment method is the same as that of a dog bite.
